#How TDD Differs from Traditional Development

[atliqtechnologies]

Test-Driven Development: Unlocking the Key to Clean and Maintainable Code

In the fast-paced world of software development, delivering high-quality code quickly is more critical than ever. Yet, according to a Consortium for IT Software Quality study, the cost of poor software quality in the US alone exceeded $2 trillion in 2022. Bugs that slip through the cracks during development can lead to skyrocketing costs, frustrated users, and even catastrophic system failures.

This is where Test-Driven Development (TDD) comes in—a methodical approach that flips traditional coding on its head by prioritizing testing before development. More than just a coding practice, TDD is a philosophy that fosters clean, reliable, and scalable software. But why does it matter so much? And how can it transform the way we build software today?

Let’s explore how TDD is reshaping development and why it should be essential to your workflow.

What is Test-Driven Development?

Test-Driven Development (TDD) is a software development methodology that emphasizes writing tests before writing the actual code. By flipping the traditional approach, TDD ensures that every piece of code serves a specific purpose and works as intended right from the start. At its core, TDD follows a simple yet powerful mantra: Red, Green, Refactor.

Key Principles: The Red, Green, Refactor Cycle

Red: Write a test for a specific functionality. Since the functionality doesn’t exist yet, the test will fail—indicated by a red signal.

Green: Write the minimum amount of code needed to pass the test. This phase ensures the test turns green, signifying that the functionality works.

Refactor: Improve the code’s structure and readability without changing its behavior. The test acts as a safety net, ensuring nothing breaks during optimization.

This cycle is repeated for every new feature or piece of functionality, promoting incremental and iterative development.

How TDD Differs from Traditional Development

Traditional Development: Developers typically write code first, then create tests afterward (if tests are written at all). This often leads to testing being deprioritized or skipped entirely.

TDD Approach: Testing is integral to the process, not an afterthought. Tests define the functionality before any code is written, ensuring clarity and purpose.

TDD fosters a test-first mindset, reducing the risk of errors and encouraging the development of modular, maintainable code. Unlike traditional methods, TDD makes debugging easier and provides immediate feedback on whether the code meets its requirements.

By championing these principles, TDD lays a strong foundation for robust software development, offering benefits that extend beyond just code quality.

Benefits of Test-Driven Development (TDD)

Test-Driven Development offers a wealth of advantages that extend beyond just testing and coding. By integrating TDD into your development process, you can achieve better software quality, seamless collaboration, and greater confidence in your codebase. Here’s a closer look at its key benefits:

1. Improved Code Quality: TDD emphasizes writing clean, modular, and testable code. Since every piece of functionality is driven by pre-written tests, the resulting code is often more structured and easier to maintain. Developers are also encouraged to break down complex problems into smaller, manageable components, leading to a more robust and scalable codebase.

2. Early Detection of Bugs: Detecting and addressing defects early in the development cycle can significantly reduce costs. A 2020 study by the Systems Sciences Institute found that fixing a bug during the testing phase costs 10 times more than addressing it during development. With TDD, tests are written upfront, making it easier to identify and resolve potential issues before they escalate.

3. Better Collaboration: TDD fosters alignment between developers, testers, and other stakeholders by clearly defining functionality through tests. These tests serve as a shared understanding of requirements, bridging the gap between development and QA teams. As a result, the entire team works cohesively toward a common goal.

4. Confidence in Refactoring: One of the biggest challenges in software development is refactoring code without unintentionally breaking existing functionality. TDD alleviates this concern by providing a safety net of tests. Developers can confidently refactor, knowing that the tests will immediately flag any regressions or inconsistencies.

5. Documentation by Tests: In TDD, the tests themselves act as living documentation for the code. Unlike traditional documentation, which can quickly become outdated, TDD’s test cases reflect the current state of the codebase. They describe how the code should behave, making it easier for new team members to understand the system.

By embracing TDD, development teams can enjoy not only better code but also smoother workflows, reduced technical debt, and higher overall productivity. It’s a win-win for developers and stakeholders alike.

Challenges of Adopting Test-Driven Development (TDD)

While Test-Driven Development offers numerous benefits, its adoption comes with challenges that teams must navigate to unlock its full potential. Here are some common hurdles organizations face when implementing TDD:

1. Steeper Learning Curve for Teams New to TDD: For developers and teams unfamiliar with TDD, the methodology can initially feel counterintuitive. Writing tests before code, adhering to the Red-Green-Refactor cycle, and maintaining test coverage require a shift in mindset. This learning curve may lead to slower progress at the beginning as teams adapt to the new workflow.

2. Perceived Increase in Initial Development Time: TDD often requires developers to spend more time upfront writing tests, which may give the impression of slower development. Teams might feel pressure to meet deadlines and perceive TDD as a roadblock. However, the time invested in writing tests early often pays off in the long run by reducing bugs and minimizing rework.

3. Possible Resistance from Developers Unfamiliar with the Approach: Change can be challenging, especially when it requires breaking long-standing habits. Developers accustomed to traditional coding methods may resist adopting TDD, viewing it as an unnecessary or overly rigid process. Overcoming this resistance requires leadership support, training, and clear communication of TDD’s long-term benefits.

How to Overcome These Challenges? 

Training and Resources: Provide workshops, tutorials, and mentoring to ease the learning process.

Gradual Implementation: Start with small projects or critical features to demonstrate TDD’s value without overwhelming the team.

Leadership Advocacy: Encourage leadership to champion TDD and emphasize its role in achieving long-term success.

Though the road to TDD adoption may be challenging, the payoff in code quality, team collaboration, and reduced technical debt makes the effort worthwhile.

Test-Driven Development is more than just a development methodology—it’s a mindset that prioritizes quality, collaboration, and confidence in code. By writing tests before implementation, teams can produce cleaner, more maintainable software while minimizing costly bugs and improving overall efficiency.

While adopting TDD may come with its challenges, the long-term benefits far outweigh the initial learning curve. It empowers developers to refactor confidently, aligns teams around clear requirements, and even provides living documentation for the codebase.

If you're looking to elevate your development process and create reliable, scalable software, TDD is a practice worth investing in. Ready to take the leap?

Advanced Software Testing Techniques for Quality

Introduction

In the rapidly evolving tech landscape, software quality is no longer a luxury—it’s a necessity. As consumers demand seamless, secure, and high-performing software, companies must adopt more advanced testing techniques to ensure quality across all aspects of development. Traditional testing methods, while effective in their own right, may not suffice in modern, complex environments.

This blog delves into advanced software testing techniques that go beyond the basics to help you maintain and enhance software quality. By leveraging these methods, businesses can stay competitive while ensuring that their software products meet both performance and security standards.

Why Advanced Testing Techniques are Critical

Modern software is more complex, interconnected, and diverse than ever before. Traditional testing techniques like manual testing and basic automated testing cover functionality, but they might miss deeper issues like performance bottlenecks, security vulnerabilities, or integration bugs. Advanced testing techniques address these challenges by offering more nuanced, powerful, and targeted solutions for specific testing needs.

Key Advanced Software Testing Techniques

1. Model-Based Testing (MBT)

Model-Based Testing (MBT) is a technique that automates test case design by using formal models that represent the system’s expected behavior. MBT generates tests based on the model, helping ensure that all functional requirements are covered.

How It Works: The tester creates a model (flowcharts, state diagrams, etc.) to represent software behavior. The model is then used to generate automated test cases that check the actual system against the expected outcomes.

Benefits:

Automated test case generation based on system models

High coverage of functional paths

Easily maintainable as models are updated with software changes

Use Cases:

Complex applications with numerous inputs and interactions

Embedded systems where manual testing is inefficient

2. Mutation Testing

Mutation testing is an advanced technique used to evaluate the quality of your test cases. The concept revolves around introducing small changes (mutations) in the program code and then running the test suite to see if the tests can detect the mutations.

How It Works: A "mutant" version of the program is created by making minor changes to the code, such as changing an arithmetic operator or a conditional statement. If the test suite detects the bug (i.e., the mutant), it is considered effective. If it doesn’t, the test suite is revised.

Benefits:

Measures the robustness of test cases

Motivates developers to create tests that are more efficient

Helps find "silent" bugs that might be missed by regular testing

Use Cases:

Testing critical systems where high fault detection is mandatory

Evaluating the effectiveness of existing test cases

3. Behavior-Driven Development (BDD)

Behavior-Driven Development (BDD) extends the idea of Test-Driven Development (TDD) by focusing on the behavior of an application from the user’s perspective. BDD uses simple, natural language (usually in the form of "Given-When-Then" statements) to describe system behavior, allowing all stakeholders to contribute to the test creation process.

How It Works: Developers, testers, and business stakeholders collaborate to create "scenarios" in plain language that describe how the software should behave. These scenarios are used as the basis for automated tests.

Benefits:

Promotes cooperation between members of the technical and non-technical teams

Reduces ambiguity in requirements by using plain language

Allows early detection of requirement mismatches

Use Cases:

Agile environments where rapid iterations require clear communication

Projects with non-technical stakeholders who need visibility into testing

4. Risk-Based Testing

Risk-Based Testing (RBT) prioritizes test cases based on the risk associated with different parts of the software. This technique focuses testing efforts on the areas most likely to fail and those that would cause the most damage if they did.

How It Works: The risk is evaluated based on two factors: the likelihood of failure and the impact of failure. Test cases are created and prioritized based on this risk assessment, ensuring that high-risk areas are tested thoroughly.

Benefits:

Efficient use of resources by focusing on critical areas

Helps prioritize testing in large, complex systems

Reduces the chance of critical failures slipping through

Use Cases:

Large, complex applications with limited testing time

Mission-critical systems where the cost of failure is high

5. Chaos Engineering

Chaos Engineering is a more radical and innovative approach, where software systems are deliberately subjected to stress or "chaos" to identify weaknesses and improve their resilience. By intentionally introducing disruptions, teams can observe how systems react and improve their fault tolerance.

How It Works: Engineers introduce controlled failures or disruptions, such as shutting down services or simulating a spike in traffic. The goal is to expose weaknesses that could lead to system failures in a real-world scenario.

Benefits:

Identifies weaknesses in complex, distributed systems

Prepares teams for potential failures in production

Improves system resilience and recovery time

Use Cases:

Cloud-native applications and microservices architectures

Systems with high availability and low downtime tolerance

6. Performance Engineering

Unlike traditional performance testing, Performance Engineering is a more holistic approach that considers performance from the early stages of software development. Instead of treating performance as an afterthought, performance engineering ensures that performance metrics are integrated into every stage of the software development lifecycle.

How It Works: By monitoring the system's performance throughout development, engineers can identify and fix performance bottlenecks early. Tools like JMeter and Gatling are often used to simulate real-world loads and test the software’s ability to handle stress.

Benefits:

Proactively prevents performance issues

Reduces time to market by addressing performance issues early

Ensures scalable and high-performing software

Use Cases:

High-traffic websites or mobile apps

Real-time data processing systems

7. Regression Test Selection

Regression testing ensures that new changes don’t negatively impact existing functionality. Regression Test Selection optimizes this process by selecting only the most relevant test cases to execute after changes, reducing the overall testing time.

How It Works: Test cases are categorized into reusable, obsolete, and retestable sets based on the changes made to the software. Only the most relevant test cases are rerun to ensure the integrity of the affected areas.

Benefits:

Saves time by reducing the number of test cases run

Prioritizes the most impactful test cases

Increases test efficiency without sacrificing coverage

Use Cases:

Continuous integration and continuous delivery (CI/CD) environments

Large-scale software projects with frequent updates

Key Benefits of Advanced Testing Techniques

Enhanced Software Quality Advanced techniques like mutation testing and chaos engineering provide deeper insights into how your software performs under stress, improving overall quality and resilience.

Optimized Testing Efficiency By focusing on high-risk areas (as in risk-based testing) or generating automated tests (like model-based testing), teams can allocate resources more effectively, ensuring maximum coverage with less effort.

Improved Collaboration Techniques like BDD encourage collaboration between technical and non-technical stakeholders, helping to align expectations and catch potential miscommunications early in the development process.

Faster Time to Market Advanced testing techniques, especially those integrated with performance engineering and regression test selection, reduce the overall testing time, allowing for quicker software releases.

Challenges in Implementing Advanced Testing Techniques

1. Skill Set Requirements Some advanced techniques require specialized knowledge, such as creating models for model-based testing or implementing chaos engineering. This may necessitate additional training for the testing team.

2. Tooling and Infrastructure Advanced testing often requires sophisticated tools and infrastructure, such as simulators for performance testing or fault injectors for chaos engineering. Investing in the right tools is essential but can be costly.

3. Complexity Techniques like mutation testing and performance engineering can add complexity to your testing processes, making them harder to manage, especially in large organizations.

Conclusion

In an era where software quality is paramount, advanced testing techniques provide a way to go beyond basic functionality checks and ensure that your software is robust, secure, and high-performing. By adopting methods like risk-based testing, model-based testing, and chaos engineering, you can not only improve your testing efficiency but also mitigate the risks associated with complex, distributed systems.

By understanding the specific needs of your project and choosing the right advanced testing techniques, you can ensure that your software is prepared to meet user expectations and business goals, all while maintaining a high standard of quality.

This is where software testing emerges as the unsung hero, ensuring that applications not only meet but exceed user expectations. In this comprehensive guide, we delve into the world of software testing, exploring its significance, methodologies, and how it contributes to the delivery of exceptional applications.

The Significance of Software Testing

Software testing serves as the cornerstone of quality assurance in the development process. Its primary objective is to identify and rectify defects before the application is released into the hands of end-users. By meticulously evaluating each component and functionality of the software, testers can mitigate risks and enhance the overall user experience. From validating functionality and performance to ensuring compatibility across different platforms and devices, software testing plays a pivotal role in maintaining the credibility and reliability of applications.

Ensuring Functional Integrity

At the heart of software testing lies the validation of functional requirements. Testers meticulously examine each feature and functionality of the application to ensure that it performs as intended. This involves conducting various tests such as unit testing, integration testing, and system testing to validate individual components and their interactions within the system. By uncovering and addressing any discrepancies early in the development cycle, testers safeguard the functional integrity of the application, thereby enhancing its usability and effectiveness.

Enhancing Performance and Scalability

Beyond functional validation, software testing also encompasses performance testing and scalability testing. Performance testing evaluates the responsiveness, stability, and speed of the application under various conditions, ensuring optimal performance across different user scenarios. Scalability testing, on the other hand, assesses the application's ability to handle increasing workloads and user interactions without compromising performance or stability. By proactively addressing performance bottlenecks and scalability challenges, testers pave the way for the seamless and efficient operation of the application, even under heavy usage.

Methodologies of Software Testing

Software testing encompasses a diverse array of methodologies, each tailored to address specific aspects of quality assurance. From traditional approaches like waterfall testing to agile methodologies like test-driven development (TDD) and behavior-driven development (BDD), testers have a plethora of techniques at their disposal to ensure comprehensive test coverage and efficient defect detection.

Waterfall Testing

In the traditional waterfall model, testing occurs in distinct phases following the sequential development process. Requirements are gathered and documented upfront, followed by design, implementation, testing, and deployment. While this approach provides a structured framework for testing, it can be rigid and less adaptable to changes late in the development cycle.

Agile Testing

Agile methodologies, such as Scrum and Kanban, have revolutionized the software development landscape by emphasizing flexibility, collaboration, and iterative development. In agile testing, testing activities are integrated throughout the development process, with continuous feedback and adaptation driving quality improvements. Test-driven development (TDD) and behavior-driven development (BDD) are popular agile practices that prioritize testing early and frequently, ensuring that code is thoroughly validated against requirements and specifications.

The Role of Automation in Software Testing

Automation has emerged as a game-changer in software testing, enabling testers to streamline repetitive tasks, accelerate test cycles, and improve overall efficiency. Through the use of robust testing frameworks and tools, such as Selenium, Appium, and JUnit, testers can automate various testing activities, including regression testing, functional testing, and performance testing. By harnessing the power of automation, organizations can achieve faster time-to-market, reduced costs, and enhanced test coverage, thereby delivering high-quality applications that exceed user expectations.

Conclusion

In conclusion, software testing transcends the mere identification and resolution of bugs; it is a multifaceted discipline that underpins the delivery of exceptional applications. From ensuring functional integrity and performance optimization to embracing agile methodologies and automation, software testing encompasses a diverse array of practices and techniques aimed at achieving excellence in software development. By prioritizing quality assurance and investing in robust testing strategies, organizations can not only mitigate risks and minimize defects but also enhance user satisfaction and drive business success in today's competitive marketplace.

Cyberpunk!HypMic

This is an extension of the cyberpunk outfits from this AU.

Originally, these outfits did not have their own universe to exist in - they were just made to fit a theme - but it just so happens HypMic already has a lot of the components required for cyberpunk...(but yikes, this is the densest AU - in terms of worldbuilding - I've had yet...)

TDD, MCD, Kuujaku Posse and NB existed in the past, but not in the context of the DRB - they were just groups of unlikely friends with differing reputations that retroactively came to be known under popular monikers and they ended up accepting those names over time. After WW3 and Chuohku's take over, technology rapidly advanced but society as a whole was wrecked.

As a reminder, the base outfit in this world is a silver body suit which only exposes the head, hands and feet, with black combat boots and a black belt.

In this world, this outfit is typically issued by Chuohku via people like Ramuda, although as you can tell by the outfits given in the magical boy AU, what you put on top of the base outfit can vary wildly. The boots and the belt can be swapped with something else without any trouble - the only thing that can get you into trouble with the authorities is ditching the suit. The body suit is able to purify polluted air within a short distance of itself, but only for the user.

All suit users have an accent colour, typically found on places like the top edge of the boots and on buttons, and the accents glow faintly in the dark. The colours have been adjusted slightly from the magical boy AU to create better glow effects.

...For the outfits that aren't specified, known from the magical boy AU or the same as canon in cases where the character does not rely on the suit, I'll leave them to your imagination, dear readers.

BB:

A team of brothers and odd jobs workers who navigate the digital and the real world to help those in need.

Ichiro: The owner of Odd Jobs Yamada. Prone to poking around with the latest in virtual reality, as well as illegal or semi-legal cybernetics. Resents Samatoki because he interferes with the Yamadas' business often enough to be a nuisance. Accent colour: Bright red.

Jiro: A delinquent and the more physical member of Odd Jobs Yamada (i.e. instead of trying to shut down bad guys using digital trickery, he's more likely to punch them instead). Was going to high school before circumstances shut schools down. Accent colour: Bright (royal) blue.

Saburo: A genius hacker. Was going to middle school before circumstances shut schools down. Accent colour: Bright yellow.

MTC:

An ad hoc crew who, in this world, have much weaker relationships than they do in canon.

Samatoki: A yakuza second-in-command, currently in possession of a strange black cybernetic glove which covers his right arm from the hand up to the elbow. The glove is able to control the air purification feature of the suits, so it's a particularly nasty bit of contraband. Resents Ichiro because Ichiro made a prototype of the glove and that was the last chance Samatoki had of convincing Nemu not to join Chuohku, but she joined them anyway. Also came into possession of an humanoid mecha, via Riou, which became the base of the new Yotsutsuji. Wears his TDD jacket over his shoulders. Accent colour: Indigo.

(Nemu: Currently with Chuohku to improve the world from within the government. Sent the completed glove to her brother because she knew he would keep it safe. Accent colour: Magenta (aka "Chuohku pink").)

Jyuto: A corrupt cop, currently investigating the glove in Samatoki's possession. More overworked than his canon counterpart...Even his trademark glasses have been digitised - they have a small antenna on the left side and can display information on the lenses when Jyuto gives them a mental signal (the display is in his accent colour). Accent colour: Maroon.

Riou: A former navyman who lives in nature, despite it being irreparably wrecked, and would rather not deal with the digital world, considering he's a cyborg (this is how he gets around not having the suit - he was experimented on in Chuohku's pursuit of creating a new supersoldier). Gave Samatoki an ancient industrial military-grade humanoid mecha which is about as tall as he (Samatoki) is.

FP:

Gentaro doesn't know Ramuda and Dice in this world.

Ramuda: A fashion designer who hands out government-mandated suits (for a small fee) while trying to ask out as many ladies as possible. Also sells other items to go with the suits, as would be expected of a typical fashion designer. His allegiance to Chuohku is a lot clearer in this world, but he's not a clone in this - just a normal human with hair dyed pink. Accent colour: Light orange (as per the magical boy AU).

Gentaro: A writer who makes his stories "real" via virtual reality and partnerships with others, such as Odd Jobs Yamada. Has material in some of his stories which he can use to blackmail Chuohku with. Hides his suit under traditional Japanese clothes. Accent colour: Bright purple.

Dice: Officially, he's a gambler who gambles with digital money and can't afford the suit. (Ramuda is not only something like a debt collector to him, he's also Dice's minder and enabler of sorts.) Unofficially, he's the son of Otome, the leader of Chuohku, who, when he was disowned by his family, lost access to the suits. As a result, he occasionally struggles to breathe and has to be helped by someone every so often. (Maybe if Hitoya or Jakurai met him in this world, Dice would be properly saved...?)

MTR:

Jakurai: A doctor, albeit one who prefers to use old-fashioned (that's "modern" to us) methods where possible. Chuohku believes gathering data from his brainwaves is necessary for the progress of developing new medical technology (or so they say...), so he wears a strange device which loops around the back half of his head and sits over his hair, attached to his head by two round (glowing) suction cups just above his ears. Wears his doctor's coat over the suit. Acts as Doppo and Hifumi's therapist and/or meditates in his spare time. Accent colour: Cyan.

Yotsutsuji: Currently in a coma after Chuohku's experiments for new supersoldiers. With the help of the former TDD, Jakurai has placed what could be salvaged of Yotsutsuji's consciousness into a humanoid mecha.

Hifumi: The no. 1 host of Fragrance. Uses virtual reality, projection mapping and other technologies to create entertainment for his clients. Afraid of women, but rather than his jacket, in this world he uses the same technology that aids him in his work to escape them. Accent colour: Neon green.

Doppo: A salaryman with appallingly low pay, no matter how hard he works, due to the fact technology is advanced enough in this world to give him a run for his money...He's lucky he has Jakurai and Hifumi to keep him sane... Accent colour: Teal.

DH:

Rei knows about Sasara and Rosho in this world, but they don't know about him.

Sasara: A comedian, currently under the heel of Chuohku. To this end, there are only certain kinds of jokes he's allowed to say while performing in public, although Sasara tries to get around this as much as he can when he can and secretly wishes to tear down the system with the former TDD + MCD so he can say what he likes again. Remotely communicates with Rosho via a visor and wears a leather jacket similar to Samatoki's TDD jacket in memory of MCD. Accent colour: Bright pink (as per the magical boy AU).

Rosho: A teacher, who lost his job when the school system broke down. He relies on Sasara to provide his basic necessities, but also takes occasional jobs to teach children in small groups or one-on-one, even teaching them comedy skills if he deems it necessary for them to survive in this wartorn world. Remotely communicates with Sasara via a display built into his glasses (which he otherwise wears purely for cosmetic reasons). Accent colour: Purple.

Rei: The creator of various technologies and creations prior to the war, most notably the ubiquitous suits. Currently gathering Jakurai's brainwave data for his own purposes. Has a strange relationship with the upper management of Chuohku, particularly Otome. Instead of sunglasses, he wears a (purely cosmetic) sniper's monocle over his left eye. Accent colour: Orange.

BAT:

Kuko: Back to being a delinquent, after people stopped believing in religion in exchange for technology. However, he still holds on to his beliefs, with the idea that one day, he can bring Buddhism back to a world that needs something to believe in. To this end, he uses virtual reality to recreate the pre-war world as he remembers it. Wears a teal happi coat over his suit and his prayer beads dangle out of his pocket. Accent colour: Mint green. Also known to commonly ditch the government-mandated suit for a particular respirator system created by Hitoya, which has a mess of wires going from the back of his head and going to either his neck or his shoulders (it looks similar to how the robot from the cover art of In My Mind's Axwell Mix has it) - this is due to the fact it looks intimidating and cool, yet it can be a pain to move around with at times.

Jyushi: A visual kei musician who enhances his shows with virtual reality, projection mapping and so on. People get confused when they involve Amanda "coming to life", but they roll with it anyway. Accent colour: Gold (essentially, a darker yellow than Saburo's).

Hitoya: A former lawyer, whose services are no longer needed now that the rules of society the law should operate in do not apply. This freed up his time to pursue his own interests, including creating portable respirator technology which Kuko and Jyushi try out for him (he does this with some help from some connections in the medical field, including Jakurai).

Iunit testing code#

Writing unit tests after you have written the production code may be a more traditional way of doing it, but it is no less useful. TDD isn't new, but at this point it is still mostly for the go getters. TDD requires a completely different mind set from what most people are used to and the tenacity to deal with a learning curve that may slow you down at first. The idea is simple, but like most simple things, the execution is hard.

Iunit testing how to#

The idea is that with a tiny bit of assurance from that initial test, the programmer can feel free to refactor and refactor some more to get the cleanest code they know how to write. Test Driven Development, or TDD, is a code design technique where the programmer writes a test before any production code, and then writes the code that will make that test pass. They can do lots of different things, they should probably only do a few. But, there are especially well suited to putting nails through hard surfaces. Hammers are great tools and can help you with lots of different jobs - opening car windows or turning off alarm clocks. A few years ago I worked for a company where this crept into the test set, eventually we had thousands of tests, set up and tear down scrips for the database, and also a test suite that took hours to run. Strictly speaking, there isn't anything wrong with crossing systems, but there are consequences like gradually slowing your tests. Small tests also have the benefit of making it harder to cross systems - from code into a database, or 3rd party system. This example is overly simple, but it gives you an idea of what I mean by small. Using Ruby, those small tests might look something like this:Ĭlass smallTest

Iunit testing software#

Look a little further and you will find SUnit, the mother of all unit testing frameworks created by Kent Beck, and a reference in chapter 5 of The Art of Software Testing. Modern versions of unit testing can be found in frameworks like JUnit, or testing tools like TestComplete. In his book "Working Effectively with Legacy Code", author Michael Feathers states that such tests are not unit tests when they rely on external systems: “If it talks to the database, it talks across the network, it touches the file system, it requires system configuration, or it can't be run at the same time as any other test." The isolated part of the definition is important. In most programming languages, that is a function, a subroutine, a method or property. A unit test is a way of testing a unit - the smallest piece of code that can be logically isolated in a system.

De”Code”-ing Automation Testing…

Over the years, the role of software testing has gained a prominent place in SDLC. The major shift towards Agile & DevOps development methodologies has expedited adoption of Test Automation strategies to bring-in speed to meet the quick go to market strategies. Software testing until last two decades was a simple exercise which was performed manually. However, it has become more complex now owing to the emergence of new technologies, platforms, browsers, devices and new development methodologies. Companies in order to meet these complex software testing requirements and to reduce their overall cost and maintenance of test cycles have realized the need to replace their traditional testing approach with Test Automation. But then considering the need of agility and to reduce the dependencies on programming skills from Testers, and to improve the communication between technical and non-technical teams (Business Analysts), slowly Behavior-Driven Development (BDD) evolved from Test-Driven Development (TDD). Writing test cases in a common language led to collaboration efficiency. This increased the demand for Codeless Automation, making it more popular approach.

Codeless Automation – 101

Codeless Automation means automating your tests without really having any knowledge of coding. Testers can visually create automated tests using a drag and drop interface, and run them on multiple browsers and work environments, simultaneously. Some of the popular tools are developed on top of open source solution, Selenium and will require zero effort from the QA team, integrates with the third-party applications, makes building test cases easier than before, monitors your web page performance and will cost less than hiring a manual tester. A few examples are Katalon Studio, CloudQA, Leapwork, Tosca, Perfecto, Mabl, Usetrace, etc.  

For QA teams, Codeless Automation reduces the complexity of writing test scripts, so they can create and execute fully automated test scenarios without coding. For developers, Codeless Automation testing makes test creation and execution substantially faster thereby saving time and focus more on product development and innovation. If automating a test case using Selenium takes a minimum of 6 hours, whereas with Codeless Automation may take only an hour. In addition, some of the Codeless testing tools use AI / ML for automated error classification, self-healing, etc making it the future in DevOps environments.

Codeless Automation workings – how?

Codeless Automation Testing can work on different approaches. The most commonly used are the record and play and creating structured test flow diagrams using drag and drop interface. The testers can edit the scripts created by the tool to best suit their requirements. This enables them to meet the shorter time to market goal.

Codeless Automation Testing Tools:

CloudQA: Easy to use cloud-based tool for creating tests using a visual editor which creates an easily maintainable dynamic test model. With record & playback option, it records the tests and captures all the actions during site navigation. It also enables running tests in parallel across browsers.

Selenium IDE: It is one of the most commonly used record and playback automation testing tool. The test scripts created can be exported to Selenium WebDriver for test execution.  The tool can be extended through plugins.

LeapWork: It is one of the popular solution for no-code test automation enabled by their visual language of flowcharts. With simple, visual building blocks, data driven tests or end to end UI test cases can be created maximizing the test coverage. With intuitive management features and straight forward integration with CI/CD pipeline, it works across all technologies.

Not just limited to these tools, there are several other popular Codeless test automation tools like Ranorex, SimplifyQA, AutonomiIQ, etc available in the market. Codeless test automation being the future to improve test efficiency, reusability, maintainability and agility, there is a substantial increase in the new codeless test automation tools in the market, every day.

Key benefits of Codeless Automation:

The main benefit of Codeless Automation is self-maintenance. Using Artificial Intelligence powered technology which eliminates maintenance time and cost as it automatically monitors changes in the code. It creates a dynamic test model that can be easily updated to reflect the changes. Codeless Testing leverages Machine Learning to self-correct object maintenance issues within code, saving time and cost. Codeless Testing on Cloud allows the team to meet its speed, scalability and collaboration needs throughout the software development life cycle (SDLC). Increased reusability and test coverage make it the best candidate for Agile and DevOps environments.

The Future of Codeless Automation:

Test automation for sure will help in accelerating regression testing, reduction in repetitive testing efforts, but codeless test automation will ensure that we achieve the desired results faster. Codeless test automation is simpler, smarter and better way to automate and drive expected ROI. Care should be taken to identify the right codeless automation tool that supports the technology in which the application is built and make sure it comes with all the required features like cross-browser compatibility, integration with different bug tracking tools, multilingual support, scheduler, etc. that ensures reliable and efficient test automation.

End-to-End Testing in Agile: All You Need to Know

Most applications today are designed with a service-oriented architecture structure. So the application is interconnected with many subsystems that can be outside of the application environment.

If there’s a failure in any of the subsystems, it can cause the entire application to crash.

So to make sure everything is working fine, we need to test the entire flow of an application from start to finish (or end-to-end).

E2E testing mainly serves two purposes:

To test the entire application for major business components such as communicating with the other systems, interfaces, databases, networks, and other applications.

To create a complete production-like scenario and test happy flow, so that we can simulate real-time settings and environment and avoid any application crash.

Why do we need End-to-End testing in Agile?

In each sprint, both the dev and test teams focus on a single service out of all the integrated services used in an application. But there are chances that they missed out on the sub-systems or services that could potentially break.

Therefore, the QA team must make sure that specific changes in a single service don’t affect the entire workflow.

How is E2E testing different from traditional testing?

Traditional testing comprises Unit, Integration, System, and UAT. But End-to-end testing is started after System testing.

Sometimes we get confused between System/Unit/Integration testing and end-to-end testing. But these are quite different.

Here’s a short example for some clarity — let’s assume we have an application with three subsystems:

Search

Order

Payment

In the current sprint, requirement specification changes in the payment subsystem are: Adding new payment options should be visible to the customers.

So as per the requirement, System testing will take care of the functionality related only to the newly added payments option.

But end-to-end testing will have the scenarios starting from Search to Payment (with newly added payment option) with the Order confirmation.

The scope, complexity, and maintenance of E2E testing are higher than that of the Unit and Integration testings.

So while preparing test cases and automation scripts, it’s always better to first understand the application architecture with the complete happy flow so that it will be easy to define the coverage.

Who can perform E2E Testing?

E2E testing should be performed by someone who has in-depth knowledge of application and aware of the product architecture. So apart from QA, a business analyst, client, product owner or even technical manager are good candidates to perform E2E testing.

End-to-end Testing Methods:

Horizontal E2E testing

It works through every phase of business workflow and ensures that the functional requirement document maps with the developed application.

A horizontal end-to-end test verifies each and every workflow through individual applications from start to finish ensuring that each interrelated process works correctly. In general this type of testing takes place at the end of release cycle and in a stable environment setup. So with this approach we can get more coverage on the functional part but it cannot be performed until all release changes are fully implemented.

Vertical E2E testing

This method refers to testing in layers, tests happen in sequential, hierarchical order. Vertical testing used to test each component separately and thoroughly, and it is more part of SDLC. Most common approach to perform this is BDD, TDD and CI-CD.

The best way to achieve it by performing unit tests for each component and then perform testing on network infrastructure, API integration and UI layers. So by using this we can get high coverage of testing for the core code. As it can be implemented in stages so easy to find defects respective to each stage.

Steps for End to End Testing Process

These are the steps essential to E2E testing:

Requirements Analysis: Analyze the requirement thoroughly and cover major business components in the E2E workflow.

Environment Set-Up: Set up a test environment keeping the production environment details in mind. Try to make it as similar to the production in terms of software and hardware requirements.

Sub-Systems: Make sure that all the sub-systems are part of E2E flow.

TestCase Design: Design test cases with maximum coverage and add test data to test common user scenarios. Focus on functionality of high priority, and design more elaborate test cases to verify it.

Execution: Execute the entire E2E test suite and then analyze the results. Never forget to run a suite in the proper sequence. If required, execute the E2E scenario in multiple browsers.

Maintain Order: Since E2E testing comprises the entire application, test cases are more complex than functional test cases. Each component of the system has to be tested, which increases failure percentage. Structure and sequence of execution are very crucial in E2E testing. Conduct unit tests and integration tests first to resolve the initial level of errors. Once end to end testing begins, simultaneously run the smoke and sanity tests with high-risk user scenarios.

How to make E2E testing in Agile more efficient:

Try to automate the E2E test cases with maximum coverage.

Keep the E2E automation suite separate from Smoke, Sanity, and BVT.

Execute E2E suite before any sprint release to make sure that the happy flow of the application is working as expected and new changes don’t have any impact on subsystems of the product.

Integrate the E2E suite with CI/CD pipeline using any tool like Jenkins.

As E2E suites take time to execute so create Jenkins job and schedule it at night so that all the failed test cases can be analyzed in the working hours.

Every so often, E2E does contain some cross-browser and parallel testing too, so in that case, try to take advantage of Selenium Grid with Docker. Use Docker containers for different browsers and execute the test cases in parallel using TestNG.

While running the E2E automation suite, it is required to create an environment similar to production and need to avoid any environment level issue, so to achieve this, you can use Docker containers.

E2E Test Deliverables

The E2E test team will create the following work products:

Test cases with detailed steps for the E2E test suite.

Enterprise test automation framework configured for the application.

Automated test execution reports and defects encountered during the End-to-End test suite.

The requirement traceability matrix will ensure that the entire requirement on the E2E workflow.

Transactional test data generated during test execution.

Documentation and manuals.

Script coding and management standards.

Script Development/Execution tracker.

Functional Issue log tracker.

Workflow diagram of the application.

Ensure maximum coverage with data, process, and logic behind the functional workflow.

Benefits of end-to-end testing:

Ensures stability and quality of product

Since the application is tested at different layers like data, business, integration, and presentation, it ensures the stability and quality of the application.

Increases Confidence on E2E Business workflow

End-to-end testing increases the confidence in the functional flow and performance before its release as the application is validated across all endpoints for different devices, browsers, platforms.

Frequent Testing Reduces Risks

As the application is tested in every iteration and sprints, it reduces the chances of any major bugs.

Reduces Repetitive Testing Efforts

End-to-end testing reduces the occurrences of frequent breakdowns and thus reduces repetitive testing efforts.

Costs Effective & Less Time

Implementing E2E testing reduces error recurrence in the later stage of product development, so fixing those issues during the early phase of the SDLC saves lots of budgets. As in E2E we make sure of the major business flows so by performing it we can avoid all major issues which can be a blockage for sprint release. Automation of the end-to-end test allows quickly adapt changing business requirements and enhance agility to the testing project.

Conclusion

The objective of end-to-end is to verify system integration with the functional flow. Thus, while testing any application, it is important to note that the user interface or presentation layer is not the only area to be focused but the underlying data, processes, and logic behind the application’s behavior need to be verified too. The connected systems and integrations are equally relevant to assure the quality of the application in terms of frontend, backend, functional flow, and integration.

ALSO READ: Learn How To Code: Google's Go (golang) Programming Language 

Jump In and Build a Spring MVC App with Spring Boot!

We'll jump right into web development with the Spring Framework. I'll show you how to kick off a Spring Boot project by using the Spring Initializr. We will then go step by step to build a simple Book / Author web application. 

You will see how easy it is to use Spring Boot, Spring MVC, and Spring Data JPA to create a functional web application running under Tomcat with an H2 in-memory database.

Use Test-Driven Development!

In addition to teaching you Spring Framework 5, you will learn about modern best practices used in enterprise application development. 

As we build the applications, you'll see me using Test Driven Development (TDD) with JUnit and Mockito.

You will learn how to test Spring applications using JUnit 4 and JUnit 5. While JUnit 5 has been released for some time, many companies are still using JUnit 4.

See how using Mockito mocks will keep your Spring Framework unit tests light and fast!

You'll also see how the Spring context can be used for more complex integration tests.

These techniques are best practices used by companies all over the world to build and manage large scale Spring Framework applications.

GitHub Source Code

You will have complete access to all source code examples used in the course.

In each lesson where we write code, you will have a link to GitHub with two branches in the Github repository. 

The first branch is the starting state of the code. 

The second branch is the ending state of the code. 

You can see exactly what changed in each lesson. Each step of the way, you have a working example you can use for troubleshooting.

In fact, you will get access to 24 (and growing!) different GitHub repositories - each packed with Spring Framework programming examples. 

And, you're encouraged to fork my GitHub repositories so you can share the Spring Framework applications, which you built, to future employers! 

Continuous Integration Builds

Since we are using GitHub and have great test coverage, I also show you how easy it is to set up Continuous Integration builds with CircleCI. 

Continuous Integration builds are another best practice used by enterprise developers. 

Using CircleCI makes your CI build a snap!

Project Lombok

We all know Java development can require a lot of boilerplate code. It's just the nature of Java.

Would you like to see how to slash your boilerplate code using Project Lombok?

Spring Data JPA and Hibernate

Spring MVC and Hibernate have long been cornerstones of the Spring Framework. You will learn how to use Spring MVC, Spring Data JPA and Hibernate to build a real-world web application. You'll learn about Hibernate configuration, and about the mapping of JPA entities. 

The Thymeleaf template engine is hugely popular with the Spring community. You will see how easy Spring Boot makes using Thymeleaf with Spring MVC.

While Bootstrap CSS is not a focus of the course, we will leverage Bootstrap CSS to make our web pages look awesome!

Spring MVC

Spring MVC has a lot of robust capabilities.

I start you off showing you how to build recipe application (using TDD, of course). 

Initially, it's all happy path development. We go back and add custom exception handling, form validation, and internationalization.

In the course, you will also learn how to use Spring MVC to create RESTful APIs.

Reactive Programming

A big theme of Spring Framework 5 is Reactive Programming. 

Inside the course, we build a web application using Thymeleaf, Spring MVC, Spring Data MongoDB, and MongoDB.

We then take the MongoDB application we built and convert it into a Reactive application. You'll see how you can leverage the new Reactive types inside the Spring Framework from the data tier to the web tier.

You will get to see step by step how to convert a traditional Spring MVC application to an end to end reactive application using the WebFlux framework - which is brand new to Spring Framework 5.

Spring Pet Clinic

Spring Pet Clinic is a classic reference application used to demonstrate best practices. The Pet Clinic application actually has its origin within the J2EE/JEE community.

The Spring Framework team took the original Pet Clinic application and rebuilt it using Spring, to demonstrate best practices.

In this course, we will re-create the Spring Pet Clinic application.

You will get to see how to create a Spring Framework application from the ground up. Step by Step.

The approach used to develop the Spring Pet Clinic application is slightly different than the other applications developed in the course.

In addition to showing you how to build a Spring Framework application, you will see best practices in software development.

We start off the Pet Clinic project by creating a GitHub repository. Then using Spring Initializer to generate the basic shell of Spring Boot project.

Next, you see how to use GitHub to mimic Agile development practices, such as using issues and a backlog.

We plan the development of the Spring Pet Clinic using GitHub Issues. Planning work into issues creates a work backlog, which is an important Agile concept.

In fact, many organizations have a formal rule that no code is changed without having an issue or some type of ticket (in Github, Jira, or some other issue tracker)

From there, we use GitHub issues to complete programming assignments. Lessons start with a GitHub ticket, then we complete the programming assignment.

You will see how to build a Spring Framework application, step by step, using best practices in software development.

Description

Learn Spring with the most modern and comprehensive course available for Spring Framework 5 and Spring Boot 2. You will see how to build multiple real world applications using Spring Framework 5.

This is the only major Spring Framework course on Udemy developed completely on version 5 of the Spring Framework.

Be careful of Spring Framework 4 courses, which have just added some content for Spring Framework 5.

The in demand technologies you will use to build Spring Framework applications, include:

Spring Framework 5

Spring Boot 2

Spring Data JPA

Spring MVC

Spring MockMVC

Spring WebFlux

Spring Web Client

Spring Data MongoDB

Spring Security (Coming in Q1 2019)

Hibernate

Project Lombok

MapStruct

Maven

Gradle

JUnit 4 and JUnit 5

Mockito

All source code examples used in this course have been developed using the latest version of the Spring Framework – Spring Framework 5 and Spring Boot 2.

You will see how modern Spring Framework development is done by leveraging the features of Spring Boot 2.

Jump In and Build a Spring MVC App with Spring Boot!

We’ll jump right into web development with the Spring Framework. I’ll show you how kick off a Spring Boot project by using the Spring Initializr. We will then go step by step to build a simple Book / Author web application.

You will see how easy it is to use Spring Boot, Spring MVC, and Spring Data JPA to create a functional web application running under Tomcat with a H2 in-memory database.

Use Test Driven Development!

In addition to teaching you Spring Framework 5, you will learn about modern best practices used in enterprise application development.

As we build the applications, you’ll see me using Test Driven Development (TDD) with JUnit and Mockito.

You will learn how to test Spring applications using JUnit 4 and JUnit 5. While JUnit 5 has been released for some time, many companies are still using JUnit 4.

See how using Mockito mocks will keep your Spring Framework unit tests light and fast!

You’ll also see how the Spring context can be used for more complex integration tests.

These techniques are best practices used by companies all over the world to build and manage large scale Spring Framework applications.

GitHub Source Code

You will have complete access to all source code examples used in the course.

In each lesson where we write code, you will have a link to GitHub with two branches in the Github repository.

The first branch is the starting state of the code.

The second branch is the ending state of the code.

You can see exactly what changed in each lesson. Each step of the way, you have a working example you can use for troubleshooting.

In fact, you will get access to 24 (and growing!) different GitHub repositories – each packed with Spring Framework programming examples.

And, you’re encouraged to fork my GitHub repositories so you can share the Spring Framework applications, which you built, to future employers!

Continuous Integration Builds

Since we are using GitHub and have great test coverage, I also show you how easy it is to set up Continuous Integration builds with CircleCI.

Continuous Integration builds are another best practice used by enterprise developers.

Using CircleCI makes your CI builds a snap!

Project Lombok

We all know Java development can require a lot of boiler plate code. It’s just the nature of Java.

Would you like to see how to slash your boiler plate code using Project Lombok?

Spring Data JPA and Hibernate

Spring MVC and Hibernate have long been cornerstones of the Spring Framework. You will learn how to use Spring MVC, Spring Data JPA and Hibernate to build a real world web application. You’ll learn about Hibernate configuration, and about the mapping of JPA entities.

The Thymeleaf template engine is hugely popular with the Spring community. You will see how easy Spring Boot makes using Thymeleaf with Spring MVC.

While Bootstrap CSS is not a focus of the course, we will leverage Bootstrap CSS to make our web pages look awesome!

Spring MVC

Spring MVC has a lot of robust capabilities.

I start you off showing you how to build recipe application (using TDD, of course).

Initially, it’s all happy path development. We go back and add custom exception handling, form validation, and internationalization.

In the course you will also learn how to use Spring MVC to create RESTful APIs.

Reactive Programming

A big theme of Spring Framework 5 is Reactive Programming.

Inside the course we build a web application using Thymeleaf, Spring MVC, Spring Data MongoDB, and MongoDB.

We then take the MongoDB application we built and convert it to a Reactive application. You’ll see how you can leverage the new Reactive types inside the Spring Framework from the data tier to the web tier.

You will get to see step by step how to convert a traditional Spring MVC application to an end to end reactive application using the WebFlux framework – which is brand new to Spring Framework 5.

Spring Pet Clinic

Spring Pet Clinic is a classic reference application used to demonstrate best practices. The Pet Clinic application actually has it’s origin within the J2EE/JEE community.

The Spring Framework team took the original Pet Clinic application and rebuilt it using Spring, to demonstrate best practices.

In this course, we will re-create the Spring Pet Clinic application.

You will get to see how to create a Spring Framework application from the ground up. Step by Step.

The approach used to develop the Spring Pet Clinic application is slightly different than the other applications developed in the course.

In addition to showing you how to build a Spring Framework application, you will see best practices in software development.

We start off the Pet Clinic project by creating a GitHub repository. Then using Spring Initializer to generate the basic shell of Spring Boot project.

Next you see how to use GitHub to mimic Agile development practices, such as using issues and a backlog.

We plan development of the Spring Pet Clinic using GitHub Issues. Planning work into issues creates a work backlog, which is an important Agile concept.

In fact, many organizations have a formal rule that no code is changed without having an issue or some type of ticket (in Github, Jira, or some other issue tracker)

From there, we use GitHub issues to complete programming assignments. Lessons start with a GitHub ticket, then we complete the programming assignment.

You will see how to build a Spring Framework application, step by step, using best practices in software development.

Everything You Need to Know About 5G

Q: What is 5G?

A: 5G is the 5th generation mobile network. It will take a much larger role than previous generations.

5G will elevate the mobile network to not only interconnect people, but also interconnect and control machines, objects, and devices. It will deliver new levels of performance and efficiency that will empower new user experiences and connect new industries. 5G will deliver multi-Gbps peak rates, ultra-low latency, massive capacity, and more uniform user experience. For the latest information on 5G, you should visit our 5G website.

Q: What are the other generations of mobile networks?

A: The other mobile network generations are 1G, 2G, 3G, and 4G.

1G delivered analog voice.

2G introduced digital voice (e.g., CDMA).

3G brought mobile data (e.g., CDMA2000).

4G LTE ushered in the era of mobile Internet.

Q. What are the benefits of 5G?

A: 5G is a new kind of network: a platform for innovations that will not only enhances today’s mobile broadband services, but will also expand mobile networks to support a vast diversity of devices and services and connect new industries with improved performance, efficiency, and cost. 5G will redefine a broad range of industries with connected services from retail to education, transportation to entertainment, and everything in between. We see 5G as technology as transformative as the automobile and electricity.

Through a landmark 5G Economy study, we found that 5G’s full economic effect will be realized across the globe by 2035, supporting a wide range of industries and potentially producing up to $12 trillion worth of goods and services.

The study also revealed that the 5G value chain (OEMs, operators, content creators, app developers and consumers) could alone generate up to $3.5 trillion in overall aggregate revenue by 2035 and support up to 22 million jobs, or more than one job for every person in Beijing, China. Of course, there are many emerging and new applications that are yet to be completely defined or even known today. That is why only time will tell what the full “5G effect” is going to be.

Q: What services and use cases do you see for 5G?

A: In general, 5G use cases can be broadly categorized into three main types of connected services:

Enhanced Mobile Broadband: 5G will not only make our smartphones better, but it will also usher in new immersive experiences, such as VR and AR, with faster, more uniform data rates, lower latency, and cost-per-bit.

Mission-Critical communications: 5G will enable new services that can transform industries with ultra-reliable/available, low latency links — such as remote control of critical infrastructure, vehicles, and medical procedures.

Massive Internet of Things: 5G will seamlessly connect a massive number of embedded sensors in virtually everything through the ability to scale down in data rates, power and mobility to provide extremely lean/low-cost solutions.

A defining capability of 5G is also the design for forward compatibility — the ability to flexibly support future services that are unknown today.

Q: How fast is 5G?

A: Per IMT-2020 requirements, 5G is expected to deliver peak data rates up to 20 Gbps.

But 5G is more than about just how “fast” it is. In addition to higher peak data rates, 5G will provide much more network capacity by expanding into new spectrum, such as millimeter wave (mmWave). 5G will also deliver much lower latency for a quicker immediate response, and an overall more uniform user experience so that the data rates stay consistently high even when users are moving around. Moreover, the new 5G NR (New Radio) mobile network will be backed up by Gigabit LTE coverage foundation, which will provide ubiquitous Gigabit-class connectivity.

Q: What are the key differentiating 5G technologies?

A: 5G is bringing a wide range of technology inventions in both the 5G NR (New Radio) air interface design as well as the 5G NextGen core network.

The new 5G NR air interface introduces many foundational wireless inventions, and in our opinion, the top five are:

Scalable OFDM numerology with 2n scaling of subcarrier spacing

Flexible, dynamic, self-contained TDD subframe design

Advanced, flexible LDPC channel coding

Advanced massive MIMO antenna technologies

Advanced spectrum sharing techniques

For more details on these key 5G NR technologies, please read this 5G NR inventions blog post.

Q: How does 5G work?

A: Like 4G LTE, 5G is also OFDM-based and will operate based on the same mobile networking principles. However, the new 5G NR (New Radio) air interface will further enhance OFDM to deliver a much higher degree of flexibility and scalability. For more details on 5G waveform and multiple access techniques, please refer to this this 5G waveform whitepaper.

5G will not only deliver faster, better mobile broadband services compared to 4G LTE, but it will also expand into new service areas, such as mission-critical communications and connecting the massive IoT. This is enabled by many new 5G NR air interface design techniques, such as a new self-contained TDD subframe design; for more detailed information on 5G and to understand the specific 5G NR design components, please refer to this 5G NR whitepaper.

Q: When is 5G coming out?

A: 5G should be available in 2019. 3GPP (3rd Generation Partnership Project, the standards body that is helping define 5G) made a decision to accelerate the initial phase of 5G NR (New Radio) — the new global 5G standard — to begin in 2019.

It is important to note that initial 5G NR deployments will focus on enhanced mobile broadband (eMBB) use cases to boost capacity and provide an elevated mobile broadband experience (faster speeds, lower latencies, etc.).

As with previous generations of mobile networks, it will take time to proliferate the new 5G network. 4G LTE will continue to grow and serve as the anchor of the 5G mobile experience (via multi-connectivity) for many years to come by providing Gigabit data rates outside 5G coverage areas.

Q: How much is 5G?

A: 5G doesn’t have a price tag yet.

A key 5G objective is to lower the cost-per-bit (data cost) compared to 4G LTE, by leveraging new and wider spectrum in higher bands including the mmWave range.

This could potentially allow mobile operators to continue offer unlimited data plans even with increasing data consumption. This can also enable new use cases and make more applications economically viable for broader adoption in a 5G network. For example, 5G can help to proliferate immersive augmented and virtual reality, which is possible today with 4G LTE but may be limited by network capacity and data costs.

Q: Who is working on 5G?

A: 5G is being driven by 3GPP, which is the standard body that also oversaw the development of 3G UMTS (including HSPA) and 4G LTE standards. 3GPP is a group of companies across the entire mobile ecosystem, all working on 5G. It ranges from infrastructure vendors and component/device manufacturers to mobile network operators and vertical service providers. Qualcomm Technologies is at the heart of the 3GPP, driving many essential inventions across all aspects of the 5G design, from the air interface to the service layer.

We expect the impact of 5G will be much greater than previous network generations. The development requirements of the new 5G network are expanding beyond the traditional mobile networking players to industries such as the automotive industry. That is why 3GPP is seeing a surge of new members that cut across a wide range of industries. It will take close collaboration among 3GPP members to make 5G a reality.

Q: What is the difference between 4G and 5G?

A: There are several differences between 4G vs 5G:

5G is a unified platform that is more capable than 4G

5G uses spectrum better than 4G

5G is faster than 4G

5G has more capacity than 4G

5G has lower latency than 4G

5G is a unified platform that is more capable than 4G

While 4G LTE focused on delivering much faster mobile broadband services than 3G, 5G is designed to be a unified, more capable platform that will not only elevate mobile broadband experiences, but also support new services such as mission-critical communications and the massive IoT. 5G will also natively support all spectrum types (licensed, shared, unlicensed) and bands (low, mid, high), a wide range of deployment models (from traditional macro-cells to hotspots), as well as new ways to interconnect (such as device-to-device and multi-hop mesh).

5G uses spectrum better than 4G

5G will also get the most out of every bit of spectrum across a wide array of available spectrum regulatory paradigms and bands — from low bands below 1 GHz, to mid bands from 1 GHz to 6 GHz, to high bands known as millimeter-wave.

5G is faster than 4G

5G will be significantly faster than 4G, delivering up to 20 Gigabits-per-second peak data rates and 100+ Megabits-per-second average data rates.

5G has more capacity than 4G

5G will support a 100x increase in traffic capacity and network efficiency1.

5G has lower latency than 4G

5G has significantly lower latency to deliver more instantaneous, real-time access: a 10x decrease in end-to-end latency down to 1ms1.

Q: What is 5G Wi-Fi?

A: 5G Wi-Fi isn’t a thing.

5G is the next-generation mobile technology defined by 3GPP (3rd Generation Partnership Project) — the standard body that also overlooked the development of 3G UMTS (including HSPA) and 4G LTE standards.

Wi-Fi is defined/standardized by IEEE and promoted/certified by the Wi-Fi Alliance, not 3GPP.

A 5G user will be able to seamlessly use 5G, 4G, and Wi-Fi since 5G will interwork both with 4G and Wi-Fi, allowing a user to simultaneously be connected to 5G New Radio (NR), LTE or Wi-Fi. Similar to Wi-Fi, 5G NR will also be designed for unlicensed spectrum without requiring access to licensed spectrum, which allows more entities to deploy 5G and enjoy the benefits of 5G technology.

300+ TOP AGILE TESTING Interview Questions and Answers

AGILE TESTING Interview Questions for freshers experienced :-

1. What is Agile Testing? Agile Testing is a practice that a QA follows in a dynamic environment where testing requirements keep changing according to the customer needs. It is done parallel to the development activity where testing team receives frequent small codes from the development team for testing. 2. What is the difference between burn-up and burn-down chart? Burn-up and burn-down charts are used to keep track the progress of the project. Burn-up charts represent how much work has been completed in any project whereas Burn-down chart represents the remaining work in a project. 3. Define the roles in Scrum? There are mainly three roles that a Scrum team have: Project Owner – who has the responsibility of managing product backlog. Works with end users and customers and provide proper requirement to the team to build the proper product. Scrum Master – who works with scrum team to make sure each sprint gets complete on time. Scrum master ensure proper work flow to the team. Scrum Team – Each member in the team should be self-organized, dedicated and responsible for high quality of the work. 4. What is Product backlog & Sprint Backlog? Product backlog is maintained by the project owner which contains every feature and requirement of the product. Sprint backlog can be treated as subset of product backlog which contains features and requirements related to that particular sprint only. 5. Explain Velocity in Agile? Velocity is a metric that is calculated by addition of all efforts estimates associated with user stories completed in a iteration. It predicts how much work Agile can complete in a sprint and how much time will require to complete a project. 6. Explain the difference between traditional Waterfall model and Agile testing? Agile testing is done parallel to the development activity whereas in traditional waterfall model testing is done at the end of the development. As done in parallel, agile testing is done on small features whereas in waterfall model testing is done on whole application. 7. Explain Pair Programming and its benefits? Pair programming is a technique in which two programmer works as team in which one programmer writes code and other one reviews that code. They both can switch their roles. Benefits: Improved code quality: As second partner reviews the code simultaneously, it reduces the chances of mistake. Knowledge transfer is easy: One experience partner can teach other partner about the techniques and codes. 8. What is re-factoring? Modification of the code without changing its functionality to improve the performance is called re-factoring. 9. Explain the Iterative and Incremental Development in Agile? Iterative Development: Software is developed and delivered to customer and based on the feedback again developed in cycles or release and sprints. Say in Release 1 software is developed in 5 sprints and delivered to customer. Now customer wants some changes, then development team plan for 2nd release which can be completed in some sprints and so on. Incremental Development:Software is development in parts or increments. In each increment a portion of the complete requirement is delivered. 10. How do you deal when requirements change frequently? This question is to test the analytical capability of the candidate. Answer can be- Work with PO to understand the exact requirement to update test cases. Also understand the risk in changing the requirement. Apart from this one should be able to write generic test plan and test cases. Don’t go for the automation until requirements are finalized. 11. What is a test stub? A small code which mimics a specific component in the system and can replace it. Its output is same as the component it replaces. 12. What qualities should a good Agile tester have? Agile tester should be able to understand the requirements quickly. Agile tester should know Agile concepts and principals. As requirements keep changing, he should understand the risk involve in it. Agile tester should be able to prioritize the work based on the requirements. Communication is must for a Agile tester as it requires a lot of communication with developers and business associates. 13. What is difference between Epic, User stories & Tasks? User Stories:User Stories defines the actual business requirement. Generally created by Business owner. Task: To accomplish the business requirements development team create tasks. Epic: A group of related user stories is called an Epic. 14. What is a Task board in Agile? Task board is dash board which shows progress of the project. It contains: User Story: which has the actual business requirement. To Do: Tasks that can be worked on. In Progress: Tasks in progress. To Verify: Tasks pending for verification or testing Done: Completed tasks. 15. What is Test Driven Development (TDD)? It is Test-first development technique in which we add a test first before we write a complete production code. Next we run the test and based on the result refactor the code to fulfill the test requirement. 16. How QA can add a value to an agile team? QA can provide a value addition by thinking differently about the various scenarios to test a story. They can provide quick feedback to the developers whether new functionality is working fine or not. 17. What is Scrum ban? It is a software development model which is combination of scrum and kanban. Scrumban is considered for maintenance projects in which there are frequent changes or unexpected user stories. It can reduce the minimum completion time for user stories. 18. What is Application Binary Interface? Application Binary Interface or ABI defines an interface for complied application programs or we can say it describes the low level interface between an application and the operating system. 19. What is Zero sprint in Agile? It can be defined as pre step to the first sprint. Activities like setting development environment, preparing backlog etc needs to be done before starting of the first sprint and can be treated as Sprint zero. 20. What is Spike? There may be some technical issues or design problem in the project which needs to be resolved first. To provide the solution of these problem “Spikes” are created. Spikes are of two types- Functional and Technical. 21. Name some Agile quality strategies. Some Agile quality strategies are- Re-factoring Small feedback cycles Dynamic code analysis Iteration 22. What is importance of daily stand up meeting? Daily stand up meeting is essential for any team in which- Team discuss about how much work has been completed. What are the plans to resolve technical issues. What steps need to done to complete the projects etc. 23. What is tracer bullet? It can be defined as spike with the current architecture or the current set of best practices. The purpose of a tracer bullet is to examine how an end-to-end process will work and examine feasibility. 24. How the velocity of sprint is measured? If capacity is measured as a percentage of a 40 hours weeks then completed story points * team capacity If capacity is measured in man hours then Completed story points / team capacity 25. What is Agile manifesto? Agile manifesto defines an iterative and people-centric approach to software development. It has basically 4 key values and 12 principals. 26. What are the Tools that can be useful for screenshots while working on Agile projects? While working on Agile projects you can use tools like BugDigger BugShooting qTrace Snagit Bonfire Usersnap 27. What are the advantages of maintaining consistent iteration length throughout the project? The advantages are It helps team to objectively measure progress It provides a consistent means of measuring team velocity It helps to establish a consistent pattern of delivery 28. If a timebox plan needs to be reprioritized who should re-prioritise it? If a timebox plan needs to be reprioritized it should include whole team, product owner, and developers. 29. What should a burndown chart should highlight? The burn-down chart shows the remaining work to complete before the timebox (iteration) ends. 30. What is the difference between Scrum and Agile? Scrum: In the scrum, a sprint is a basic unit of development. Each sprint is followed by a planning meeting, where the tasks for the sprint are identified and estimated. During each sprint, the team creates finished portion of a product Agile: In Agile, each iteration involves a team working through a full software development cycle, including planning, design, coding, requirement analysis, unit testing, and acceptance testing when a product is demonstrated to stakeholders In simple words, Agile is the practice and scrum is the process to following this practice. 31. What are the challenges involved in AGILE software development? Challenges involved in Agile Software development includes It requires more testing and customers involvement It impacts management more than developers Each feature needs to be completed before moving on to the next All the code has to work fine to ensure application is in working state More planning is required 32. When not to use Agile? Before using Agile methodology, you must ask following questions Is functionality split-able Is customer available Are requirements flexible Is it really time constrained Is team skilled enough 33. How can you implement scrum in an easy way to your project? These are the tips which can be helpful to implement scrum in your project Get your backlog in order Get an idea of the size of your product backlog items Clarify sprint requirement and duration to complete the sprint backlog Calculate the team sprint budget and then break requirements into tasks Collaborate workspace- a center of all team discussion, which includes plans, roadmaps, key dates, sketches of functionality, issues, log, status reports, etc. Sprint- Make sure you complete one feature at a time before moving on to the next. A sprint should not be abort unless if there is no other option Attend a daily stand-up meeting: In meeting you need to mention, what have been achieved since the last meeting, what will they achieve before the next meeting and is anything holding up their progress Use burndown chart to track daily progress.

Teaching rigorous distributed systems with efficient model checking

Teaching rigorous distributed systems with efficient model checking Michael et al., EuroSys’19

On the surface you might think today’s paper selection an odd pick. It describes the labs environment, DSLabs, developed at the University of Washington to accompany a course in distributed systems. During the ten week course, students implement four different assignments: an exactly-once RPC protocol; a primary-backup system; Paxos; and a scalable, transactional key-value storage system. 175 undergraduates a year currently go through this course. Enabling students to build running performant versions of all of those systems in the time available is one challenge. Testing and grading their solutions is another!

Although we added tests to catch specific issues as we learned of them, we found it difficult to keep up with the diversity of possible student errors.

What I like about the paper is that (a) the DSLabs framework and all assignments are available in open source, and it looks like it would be a lot of fun to play with, and (b) the challenges students have to face in building reliable, testable, distributed systems under time pressure look pretty much like the challenges many practitioners have to face to me! So by focusing on what it takes to help students be successful in this context, we can also derive some inspiration for building systems in the wild too.

DSLabs combines traditional testing with model checking:

Faced with the challenges of building robust distributed systems and the inadequacies of other methodologies, both academic research and industry have increasingly turned to model checking to validate system correctness. Model checking overcomes the weakness of ad hoc testing by systematically exploring all possible executions, but without the high labor cost of formal verification.

At this point you might think of turning to TLA+. However, it’s difficult to master this environment and learn core distributed systems concepts in a single term, and moreover a model checked TLA+ specification still has to then be implemented in some language. Hence the DSLabs framework integrates model checking into a holistic distributed systems development environment (based on Java as the implementation language – it would be neat to see a Rust version!).

This paper introduces DSLabs, a framework for writing, testing, model checking, running, and debugging distributed systems, along with a sequence of assignments written to use the framework.

In the core programming model, students provide implementations of Node subclasses which specify the behaviour of individual nodes in their distributed systems. Each node runs in a single threaded event loop. The interface is pretty straightforward:

The only thing that looks slightly odd on first glance in that interface is the set timer method that takes a min duration and max duration. To make things easily testable, all handlers are required to be deterministic. But hang on a minute you may say, isn’t a little randomness very useful in constructing distributed systems? Yes it is! In the DSLabs environment the only allowable randomness is encapsulated in that timer call, which will expire the timer at a random time between the min and max parameter values.

Clients are also implemented as Nodes. Worker drivers are provided by the tutors and execute a pre-determined workload using clients written by students.

The networking model is asynchronous (allowing out of order, dropped, delayed, and duplicated messages), the failure model is crash-stop.

Testing and model checking

One of the goals of DSLabs is for students to create runnable distributed systems. We would like students to consider the performance characteristics of their systems, and our tests check that their designs attain reasonable run-time performance.

It’s hard to exhaustively test a distributed system with traditional testing techniques. So DSLabs also uses model checking. Consider the lab exercise to implement Paxos. One common implementation error (i.e., one observed being made by many students) is to accept a value being proposed without also checking the proposal number (see full explanation in §3.1 of the paper).

While this bug could cause a violation of linearizability, witnessing such a violation would be rare… In light of our goal of providing a thorough suite of tests, not being able to find a common bug like this one is problematic! On the other hand, model checking can find this bug reliably.

So we need an approachable model checking solution that doesn’t come with a steep learning curve, and can find common bugs in a timely fashion. These twin requirements led DSLabs to incorporate its own lightweight model checking solution. In addition, another lesson here is that once we accept model checking is necessary, we need to design systems that are amenable to model checking.

I would be nice if students did not have to take model checking into consideration (aside from ensuring their systems meet the basic requirements…). If this were true, the model checking tests we provide would simply be better tests which reliably caught distributed systems bugs. However, systems design decisions can have a large impact on the performance of the model checker, and thus its ability to find bugs within a reasonable amount of time.

The heuristic advice given to students is as follows:

Favour simplicity above all else

Do not keep or send unnecessary state

Explore performance optimisations, but not at the expense of significant added complexity

Consider the number of events it takes for your system to make progress from any state; ensure that number is reasonably close to the minimum.

Luckily, code that is readily model checkable usually corresponds to the kind of code we want students to write — code that is as simple as possible with respect to its state graph.

As we saw earlier, the DSLabs model checker requires deterministic handlers. It collapses equivalent states to avoid wasting work during model checking (in this case, based on equals and hashCode methods generated for students by Project Lombok). Even then, the state space can be huge (e.g. exponential in n, where n is the number of steps). The model checker needs to provide timely feedback rather than having it run for hours and hours every time. So DSLabs uses two basic strategies to focus the search in the areas most likely to be fruitful:

We’d like to know how deep into the graph we need to explore. One way to do this is to ensure the model checker has gone deep enough for the system to be able to make progress. So we can search for states in which progress has been made, and assume that this depth is also enough as a first pass to find not only states where we have made good progress, but also states where we take ‘bad’ actions.

There will still remain places where the model checker needs to probe deeper. For example, the Paxos bug alluded to earlier takes a minimum of 36 steps to trigger. DSLabs uses a guided search strategy here, using knowledge about each system’s specification to guide the model checker’s search to more interesting and error-prone parts of the state space. Prunes are predicates telling the model checker which states not to expand. Punctuated search first looks for states satisfying some intermediate constraint, and then restarts a (deeper) search from there.

DSLabs post-processes failing traces to present them in the easiest to understand form possible for students, with events laid out in causal order wherever possible.

A visual debugger/system explorer

DSLabs also includes a visual debugger called Oddity, which can be used to explore system behaviour. Oddity will also start automatically when the model checker finds an invariant violation. It looks like this:

Teaching distributed systems using DSLabs

The following table shows the LOC count for the reference implementations of each assignment in DSLabs.

A solution implemented in TLA+ would likely be smaller, but only modestly so, at the expense of students needing to learn a completely new language.

The table above also shows wall clock time for running the tests (including model checking). The DSLabs test suite can give useful feedback in six minutes or less (on the reference solutions), fast enough to be part of an iterative development process.

This supports our goal of giving students timely feedback… Prior to adding model checking, it was common for students to find bugs in their Paxos implementation only when they tried to use that implementation in a later lab. By catching student errors more quickly , we reduce the amount of rework needed.

For the Paxos bug described earlier, the DSLabs guided search can find it in 18 seconds. As a comparison, an unguided search took an average of 12 hours to do so.

The hardest part of the class for many students is learning to think about their code as inherently distributed. This in turn requires thinking about the invariants maintained by the system over all possible event sequences simultaneously. It highlights a case where students, perhaps trained on good TDD practices (do students get taught that these days??) and used to taking small incremental steps, fail to appreciate the need for some degree of up-front design. (Of course, we never make that mistake in industry;) ).

Students often march though test cases incrementally, fixing problems only once they occur. A particular student tried this for the primary-backup assignment and got stuck: the fix for a problem found by one test would often break the solution for previous tests. The student found he could find a version to pass each of the tests, just not the same version. After we encouraged him to start over with a clean design that met all of the criteria simultaneously, he was able to quickly converge on a solution.

The model checking was a big help here as it surfaced bugs students may not have realised were latent in their code.

The last word

Using the DSLabs framework and assignments, we have successfully guided hundreds of students through the process of building a fault-tolerant, scalable, distributed key–value store. Furthermore, these student-built systems are actually runnable, rather than mere specifications; they can be deployed in a fully distributed fashion and can achieve considerable performance.

I’ll leave you with another reminder that if you want to play with it, the labs environment and assignments can all be found on GitHub…

Be careful of Spring Framework 4 courses, which have just added some content for Spring Framework 5. The in demand technologies you will use to build Spring Framework applications, include: Spring Framework 5 Spring Boot 2 Spring Data JPA Spring MVC Spring MockMVC Spring WebFlux Spring Web Client Spring Data MongoDB Spring Security (Coming in Q4 2018) Hibernate Project Lombok MapStruct Maven Gradle JUnit 4 and JUnit 5 Mockito All source code examples used in this course have been developed using the latest version of the Spring Framework - Spring Framework 5 and Spring Boot 2. You will see how modern Spring Framework development is done by leveraging the features of Spring Boot 2.  Jump In and Build a Spring MVC App with Spring Boot! We’ll jump right into web development with the Spring Framework. I’ll show you how kick off a Spring Boot project by using the Spring Initializr. We will then go step by step to build a simple Book / Author web application.  You will see how easy it is to use Spring Boot, Spring MVC, and Spring Data JPA to create a functional web application running under Tomcat with a H2 in-memory database. Use Test Driven Development! In addition to teaching you Spring Framework 5, you will learn about modern best practices used in enterprise application development.  As we build the applications, you’ll see me using Test Driven Development (TDD) with JUnit and Mockito. You will learn how to test Spring applications using JUnit 4 and JUnit 5. While JUnit 5 has been released for some time, many companies are still using JUnit 4. See how using Mockito mocks will keep your Spring Framework unit tests light and fast! You’ll also see how the Spring context can be used for more complex integration tests. These techniques are best practices used by companies all over the world to build and manage large scale Spring Framework applications. GitHub Source Code You will have complete access to all source code examples used in the course. In each lesson where we write code, you will have a link to GitHub with two branches in the Github repository.  The first branch is the starting state of the code.  The second branch is the ending state of the code.  You can see exactly what changed in each lesson. Each step of the way, you have a working example you can use for troubleshooting. In fact, you will get access to 24 (and growing!) different GitHub repositories - each packed with Spring Framework programming examples.  And, you’re encouraged to fork my GitHub repositories so you can share the Spring Framework applications, which you built, to future employers!  Continuous Integration Builds Since we are using GitHub and have great test coverage, I also show you how easy it is to set up Continuous Integration builds with CircleCI.  Continuous Integration builds are another best practice used by enterprise developers.  Using CircleCI makes your CI builds a snap! Project Lombok We all know Java development can require a lot of boiler plate code. It’s just the nature of Java. Would you like to see how to slash your boiler plate code using Project Lombok? Spring Data JPA and Hibernate Spring MVC and Hibernate have long been cornerstones of the Spring Framework. You will learn how to use Spring MVC, Spring Data JPA and Hibernate to build a real world web application. You’ll learn about Hibernate configuration, and about the mapping of JPA entities.  The Thymeleaf template engine is hugely popular with the Spring community. You will see how easy Spring Boot makes using Thymeleaf with Spring MVC. While Bootstrap CSS is not a focus of the course, we will leverage Bootstrap CSS to make our web pages look awesome! Spring MVC Spring MVC has a lot of robust capabilities. I start you off showing you how to build recipe application (using TDD, of course).  Initially, it’s all happy path development. We go back and add custom exception handling, form validation, and internationalization. In the course you will also learn how to use Spring MVC to create RESTful APIs. Reactive Programming A big theme of Spring Framework 5 is Reactive Programming.  Inside the course we build a web application using Thymeleaf, Spring MVC, Spring Data MongoDB, and MongoDB. We then take the MongoDB application we built and convert it to a Reactive application. You’ll see how you can leverage the new Reactive types inside the Spring Framework from the data tier to the web tier. You will get to see step by step how to convert a traditional Spring MVC application to an end to end reactive application using the WebFlux framework - which is brand new to Spring Framework 5. Spring Pet Clinic Spring Pet Clinic is a classic reference application used to demonstrate best practices. The Pet Clinic application actually has it’s origin within the J2EE/JEE community. The Spring Framework team took the original Pet Clinic application and rebuilt it using Spring, to demonstrate best practices. In this course, we will re-create the Spring Pet Clinic application. You will get to see how to create a Spring Framework application from the ground up. Step by Step. The approach used to develop the Spring Pet Clinic application is slightly different than the other applications developed in the course. In addition to showing you how to build a Spring Framework application, you will see best practices in software development. We start off the Pet Clinic project by creating a GitHub repository. Then using Spring Initializer to generate the basic shell of Spring Boot project. Next you see how to use GitHub to mimic Agile development practices, such as using issues and a backlog. We plan development of the Spring Pet Clinic using GitHub Issues. Planning work into issues creates a work backlog, which is an important Agile concept. In fact, many organizations have a formal rule that no code is changed without having an issue or some type of ticket (in Github, Jira, or some other issue tracker) From there, we use GitHub issues to complete programming assignments. Lessons start with a GitHub ticket, then we complete the programming assignment. You will see how to build a Spring Framework application, step by step, using best practices in software development.
