QA vs. Software Testing: What's the Difference and Why It Matters

In the world of software development, terms like Quality Assurance (QA) and Software Testing are often used interchangeably. However, while both contribute to software quality, they serve distinct purposes.

Think of QA as the blueprint that ensures a house is built correctly, while software testing is the process of inspecting the finished house to ensure there are no cracks, leaks, or faulty wiring. QA is proactive—preventing defects before they occur, whereas software testing is reactive—detecting and fixing bugs before deployment.

Understanding the difference between QA and software testing is crucial for organizations to build reliable, high-performing, and customer-friendly software. This blog explores their differences, roles, and why both are essential in modern software development.

What is Quality Assurance (QA)?

Quality Assurance (QA) is a systematic approach to ensuring that software meets defined quality standards throughout the development lifecycle. It focuses on process improvement, defect prevention, and maintaining industry standards to deliver a high-quality product.

Instead of identifying defects after they appear, QA ensures that the development process is optimized to reduce the likelihood of defects from the beginning.

Key Characteristics of QA:

Process-Oriented: QA defines and improves the software development processes to minimize errors.

Preventive Approach: It prevents defects before they arise rather than finding and fixing them later.

Covers the Entire Software Development Lifecycle (SDLC): QA is involved from requirement gathering to software maintenance.

Compliance with Industry Standards: QA ensures the software adheres to ISO, CMMI, Six Sigma, and other quality benchmarks.

Key QA Activities:

Defining Standards & Guidelines – Establishing coding best practices, documentation protocols, and process frameworks.

Process Audits & Reviews – Conducting regular audits to ensure software teams follow industry standards.

Automation & Optimization – Implementing CI/CD (Continuous Integration/Continuous Deployment) to streamline development.

Risk Management – Identifying potential risks and mitigating them before they become major issues.

Example of QA in Action:

A company implementing peer code reviews and automated CI/CD pipelines to ensure all new code follows quality guidelines is an example of QA. This process prevents poor-quality code from reaching the testing phase.

What is Software Testing?

Software Testing is a subset of QA that focuses on evaluating the actual software product to identify defects, errors, and performance issues. It ensures that the software behaves as expected and meets business and user requirements.

Testing is performed after the development phase to verify the correctness, functionality, security, and performance of the application.

Key Characteristics of Software Testing:

Product-Oriented: Testing ensures the final product works as expected and meets user requirements.

Defect Detection & Fixing: The main goal is to identify and fix bugs before software release.

Different Testing Methods: Includes manual and automated testing, covering functionality, usability, performance, security, and compatibility.

Part of the Software Testing Life Cycle (STLC): Testing occurs after development and follows a structured cycle of planning, execution, and bug tracking.

Types of Software Testing:

Functional Testing: Verifies that the software functions as per the requirements.

Unit Testing: Checks individual components or modules.

Integration Testing: Ensures different modules work together correctly.

System Testing: Tests the complete application to validate its behavior.

Performance Testing: Measures speed, scalability, and responsiveness.

Security Testing: Identifies vulnerabilities to prevent security breaches.

Example of Software Testing in Action:

Running automated UI tests to check if a login form accepts correct credentials and rejects incorrect ones is an example of software testing. This ensures that the application meets user expectations.

Key Differences Between QA and Software Testing

Focus: Quality Assurance (QA) is a process-oriented approach that ensures the entire software development process follows best practices and quality standards to prevent defects. In contrast, software testing is product-oriented and focuses on detecting and fixing bugs in the developed software.

Goal: The primary goal of QA is to prevent defects from occurring in the first place by refining development and testing methodologies. On the other hand, software testing aims to identify and fix defects before the software is released to users.

Scope: QA encompasses the entire Software Development Life Cycle (SDLC), ensuring that each phase—from requirement analysis to deployment—adheres to quality standards. In contrast, software testing is a subset of QA and is mainly concerned with validating the functionality, performance, security, and reliability of the software.

Approach: QA follows a proactive approach by setting up quality checkpoints, code reviews, and documentation processes to reduce the chances of defects. Software testing, however, takes a reactive approach, meaning it focuses on identifying existing issues in the software after the development phase.

Activities Involved: QA activities include process audits, documentation reviews, defining coding standards, implementing CI/CD pipelines, and process optimization. In contrast, software testing involves executing test cases, performing unit testing, integration testing, functional testing, performance testing, and security testing to ensure the software meets the required specifications.

Example of Implementation: A company implementing peer code reviews, automated build testing, and compliance audits as part of its development process is engaging in QA. On the other hand, running test cases on a login page to check if valid credentials allow access while invalid ones do not is an example of software testing.

By understanding these differences, organizations can ensure they integrate both QA and testing effectively, leading to higher software quality, fewer defects, and a better user experience.

Why Both QA and Software Testing Matter

Some organizations mistakenly focus only on testing, believing that identifying and fixing bugs is enough. However, without strong QA practices, defects will continue to arise, increasing development costs and delaying software delivery. Here’s why both QA and testing are crucial:

1. Ensures High-Quality Software

QA minimizes errors from the start, while testing ensures no critical issues reach the end-user.

Organizations following robust QA practices tend to have fewer post-release defects, leading to better product stability.

2. Reduces Cost and Time

Finding a bug during requirement analysis is 10x cheaper than fixing it after deployment.

QA ensures that software defects are avoided, reducing the need for excessive testing and bug-fixing later.

3. Enhances User Experience

A well-tested software application performs smoothly without crashes or failures.

Poor QA and testing can result in negative user feedback, harming a company’s reputation.

4. Supports Agile and DevOps Practices

In Agile development, continuous QA ensures each sprint delivers a high-quality product.

DevOps integrates QA automation and continuous testing to speed up deployments.

5. Helps Meet Industry Standards & Compliance

Industries like finance, healthcare, and cybersecurity have strict quality standards.

QA ensures compliance with GDPR, HIPAA, ISO, and PCI DSS regulations.

How to Balance QA and Testing in Your Software Development Process

Implement a Shift-Left Approach: Start QA activities early in the development cycle to identify defects sooner.

Adopt CI/CD Pipelines: Continuous integration and automated testing help streamline both QA and testing efforts.

Use Test Automation Wisely: Automate repetitive test cases but retain manual testing for exploratory and usability testing.

Invest in Quality Culture: Encourage developers to take ownership of quality and follow best practices.

Leverage AI & Machine Learning in Testing: AI-driven test automation tools can improve defect detection and speed up testing.

Conclusion

While QA and software testing are closely related, they are not the same. QA is a preventive, process-oriented approach that ensures quality is built into the development lifecycle. In contrast, software testing is a reactive, product-focused activity that finds and fixes defects before deployment.

Organizations that balance both QA and testing effectively will consistently build high-quality, defect-free software that meets user expectations. By implementing strong QA processes alongside thorough testing, companies can save costs, speed up development, and enhance customer satisfaction.

Best Practices of Regression Testing to Follow

Regression testing ensures that changes in code do not introduce new bugs or break existing functionality. By following best practices for regression testing, teams can maintain high-quality software throughout its lifecycle.

Here are some essential best practices:

1. Automate Regression Tests

Why: Manually running tests is time-consuming and prone to error. Automation speeds up the process and ensures consistency.

How: Use test automation tools (e.g., Selenium, JUnit, TestNG) to script and execute repetitive regression tests. Focus on automating stable, high-priority tests.

2. Prioritize Test Cases

Why: Not all test cases are equally critical. Running every test is often impractical, especially for large systems.

How: Prioritize test cases based on factors like the impact of the changes, criticality of the feature, and frequency of usage. Run critical tests first (e.g., smoke tests) before expanding to others.

3. Maintain an Updated Test Suite

Why: The regression test suite should reflect the current state of the application. As features evolve or are deprecated, the test suite should be updated accordingly.

How: Regularly review and refactor your test cases. Remove obsolete tests, update tests for modified functionality, and add tests for new features.

4. Use Continuous Integration (CI)

Why: Continuous integration helps identify issues as soon as code is changed or merged, ensuring immediate feedback.

How: Integrate regression testing into the CI pipeline (using Jenkins, GitLab CI, CircleCI, etc.), so tests are run automatically after every code change.

5. Perform Smoke Testing Before Full Regression

Why: A smoke test checks the critical functionality before running the full suite. This can save time by ensuring that major components work before diving into detailed tests.

How: Run a small subset of high-priority tests that cover the most critical paths after each build. If the smoke test passes, proceed to full regression testing.

6. Monitor Test Coverage

Why: It’s crucial to ensure that your regression tests provide sufficient coverage across different parts of the application.

How: Use tools to measure test coverage (e.g., code coverage tools like JaCoCo for Java). Ensure that new features or bug fixes are backed by tests that sufficiently cover the affected code paths.

7. Perform Risk-Based Testing

Why: Some areas of your codebase might be more prone to bugs than others.

How: Focus regression tests on high-risk areas, including modules with frequent changes or historically high defect rates. Also, consider testing integrations with other components.

8. Parallelize Tests for Faster Execution

Why: Running tests sequentially can be slow, especially with a large test suite.

How: Use parallel execution techniques where possible. Tools like Selenium Grid or cloud-based platforms like BrowserStack allow tests to be run in parallel across different environments.

9. Incorporate Exploratory Testing

Why: Automation may not catch all issues, especially subtle bugs or issues stemming from unusual user behavior.

How: Complement your regression testing with exploratory testing, where testers manually explore the application without predefined test cases to discover potential problems.

10. Monitor and Report Test Results

Why: Knowing the outcome of each regression test cycle is crucial to understanding application health.

How: Ensure that test results are logged and reported clearly to the development team. Many CI tools can generate detailed reports that highlight failed tests and provide insights into why they failed.

11. Optimize for Performance

Why: Over time, regression suites can grow and become unwieldy. Long execution times slow down the development cycle.

How: Continuously review and optimize the suite by removing redundant tests, breaking large test cases into smaller, more efficient ones, and using techniques like test parallelization.

12. Use Version Control and Baseline Comparisons

Why: Regression testing compares the current state of the application to its previous state, so you need clear records of past behaviors.

How: Use version control systems (e.g., Git) to manage test scripts, and maintain baselines for regression tests so you can compare results after each change.

13. Incorporate Different Test Environments

Why: Testing in different environments (operating systems, browsers, hardware) ensures broader coverage.

How: Use tools like Docker for environment consistency or cloud-based services for testing across different environments. This ensures your application works as expected under varied conditions.

14. Regularly Analyze and Refine Test Strategy

Why: Software development is iterative, and so should your testing strategy.

How: Regularly revisit your regression testing approach to ensure it’s still aligned with project needs, technology stack changes, and product goals.

By following these best practices, regression testing can become a powerful tool for maintaining software quality over time, ensuring both efficiency and reliability in the development process.

In today’s fast-paced software development world, manual test design fails to keep up with rapid releases and evolving application features. Test automation has become essential, but automating test design itself is the next big step in ensuring high-quality software with minimal effort. 

Automated test design reduces human errors, improves test coverage, and integrates seamlessly with modern DevOps and workflows. This is where GhostQA plays a key role by offering an AI-powered test automation solution that generates, optimizes, and executes test cases efficiently. 

In this blog, we’ll explore the importance of automating test design, key approaches, benefits, and how GhostQA is transforming the landscape of test automation. 

Why Automate Test Design? 

Automating test design is about removing manual bottlenecks and allowing software teams to: 

Speed Up Test Case Generation – Automated tools like GhostQA create test cases within minutes, reducing manual effort. 

Enhance Test Coverage – AI-driven automation ensures all critical scenarios are tested, including edge cases. 

Improve Accuracy – Eliminates human errors in designing test cases, resulting in more reliable testing. 

Support Scalability – Automated test design adapts to continuous changes in Agile and DevOps pipelines.

With AI and machine learning transforming QA, GhostQA simplifies test automation by providing smart test design solutions that accelerate testing processes. 

Key Approaches to Automating Test Design 

1. Model-Based Test Design (MBT) 

Model-Based Testing (MBT) automates test generation by creating visual models of an application’s behavior. Instead of manually writing test cases, testers define models that automatically generate test cases. 

How GhostQA Helps: 

GhostQA simplifies model-based test generation by analyzing application workflows and creating automated test cases. 

Optimized test selection ensures maximum coverage while avoiding redundant tests. 

2. AI and Machine Learning in Test Design 

AI-driven test design uses historical test data, user behavior, and risk analysis to predict and generate the most relevant test cases. 

How GhostQA Helps: 

AI-Powered Test Creation – GhostQA analyzes test data patterns to generate the most impactful test cases. 

Self-Healing Test Scripts – If the UI changes, GhostQA automatically updates scripts to reduce maintenance effort. 

3. Scriptless Test Automation 

Traditional test scripting requires programming knowledge, but scriptless automation allows testers to create automated tests without coding. 

How GhostQA Helps: 

Drag-and-Drop Interface – GhostQA offers a scriptless test design, making it accessible for both testers and developers. 

Faster Execution – Automates repetitive tasks, reducing test creation time by up to 70%. 

4. Risk-Based Test Design 

Not all tests have the same impact; some are more critical than others. Risk-based test automation prioritizes tests based on business impact and risk analysis. 

How GhostQA Helps: 

AI-Powered Risk Analysis – GhostQA automatically identifies high-risk areas and prioritizes test execution accordingly. 

Intelligent Test Selection – Reduces test execution time while maintaining high software quality. 

Challenges in Automating Test Design 

Even with automation, test design comes with challenges: 

Choosing the Right Tools – Selecting an automation tool that integrates well. 

Initial Setup Effort – Configuring AI-driven automation requires a learning curve. 

Maintenance Overhead – Automated tests require updates when application logic changes. 

GhostQA addresses these challenges by offering:  ✔ Seamless Integration with DevOps pipelines.  ✔ AI-Driven Adaptive Testing to minimize test maintenance.  ✔ Pre-Built Testing Frameworks to reduce setup efforts.

What are software testing techniques

Application testing is an important phase in the software development life cycle, whose main goal is to verify the functionality of a piece of software and its compliance with the required specifications. The basic purpose of many techniques is to assess some facet of the software to reveal problems, validate operations, and measure performance. Here’s an overview of the key software testing techniques: 

  1. Black Box Testing  Black box testing is a method of software testing whereby the person testing does not require any information about how the examined application works. In this process, the tester only inputs data into the software and only reads processing results without knowing the program code and its structure. The primary goal here is the usage of the application and its ability to perform in a desired manner. Common black box testing techniques include: 

  Equivalence Partitioning: Partition testing is a technique that checks one element in each of the divisions of the input data where the reaction of the software is supposed to be similar.  Boundary Value Analysis: Checking the edges and the line in between the partitions there most probably would be mistakes.  Decision Table Testing: Develop a decision table that includes all possible input combinations of the problem and decides in advance the outcome that each combination should produce to exhaust all possibilities.  State Transition Testing: Verifying the movement of the software from one state to another to determine its behavior where the system’s behavior is relative to the current state. 

2. White Box Testing 

Clear box, glass box, or white box testing is a kind of testing in which the internal workings of an application are tested. The tester is aware of the internal code and architecture and designs tests to make certain that the inside operations run as they are supposed to. Key techniques under white box testing include: 

Unit Testing: The process of verifying an individual module or portion of the entire software so that that particular section of it works properly. 

Code Coverage Analysis: Calculating the ratio of the code sizes as covered by the tests, to have high coverage, thus getting better tests for most parts of the code. 

Statement Coverage: The need to guarantee that all the statements in the program code are run at least once. 

Branch Coverage: It means checking all the possible branches (true or false) in the code. 

Path Coverage: Making Sure all paths of the code have been covered by the test. 

Control Flow Testing: Controlling the flow of the software through explicit and repetitive tests to identify control structures such as loops and conditions. 

3. Grey Box Testing 

Grey box testing is considered as an infiltration of black box and white box testing. Here, the tester has a limited understanding of the app’s flow and how it is structured, which makes the testing process better. The technique is particularly useful in integration testing where all the internal elements as well as the interfaces are tested. 

4. Static Testing 

Static testing is a software testing method in which the software’s code, documentation, and any other tangible requirements are inspected without the usage of the application. This technique is usually applied to find out different defects at the initial stage of development. Common static testing techniques include: 

Code Reviews: Code reviews by other students or programmers to find problems ranging from pentad logic mistakes or operational errors, violations of guidance for coding practices, or the presence of flaws that are likely to emerge as bugs. 

Static Analysis Tools: Static analysis tools that crawl through the source code looking for issues such as vulnerabilities, code smells, and other defects but do not run the program. 

Walkthroughs and Inspections: Pre-scheduled sessions in which the development team reviews the design of the software, implementation code, or any other entity that has been developed to find faults. 

5. Dynamic Testing 

In dynamic testing, one runs the software and looks for problems, and ensures that the software operates correctly. It applies to all levels of testing which includes unit testing, integrated testing, system testing, and even acceptance testing. Key dynamic testing techniques include: 

Functional Testing: Mainly, the testing is done to ensure that the software operates as it is required to do as per the specifications provided. 

Non-Functional Testing: This is the exercise of the software to check on its non-functional features like speed, ease of use, and insecurity. 

Performance Testing: Evaluating the performance of the software: The ability of software to respond to various situations, its stability, and how it utilizes the available resources. 

Load Testing: Benchmarking of the application to check how the software works when a high amount of load is applied. 

Stress Testing: The process of putting the software through pressure to determine its ability to deal with stress or overloading. 

Regression Testing: Performing regression testing where an application is run again to confirm that the changes that have been made do not introduce new faults. 

6. Exploratory Testing 

Exploratory testing is an informal, ad-hoc testing technique in which the tester tends to test the application without any prior prepared scripts. The tester is experienced and applies his/her logic to determine situations that may likely have defects and then creates and runs tests on the spot. This technique is very helpful in finding unknown problems and getting better insight into the software system when it is used in the real environment. 

7. Acceptance Testing 

Acceptance testing is done with the purpose of testing the software to its business requirements and its suitability for deployment. This testing is mostly done by the customers or the end-users to ascertain that the software offers the required value. Key types of acceptance testing include: 

User Acceptance Testing (UAT): Verifying the developed software against the requirements of the users, as to whether they have been met. 

Operational Acceptance Testing (OAT): Affirming that all software is ‘production ready’, that is, backup/restore disaster recovery, and maintenance. 

Conclusion 

Software testing is a vital and integral component of the whole software development life cycle as it helps to determine that the delivered product is both safe to use and operator-friendly. Using methods like black box, white box, grey box, static and dynamic, exploratory and acceptance tests, testers can be sure in the product quality determination and in early defects’ detection for contributing to the product success solely. All the technique has specific uses and altogether they build a comprehensive coverage of the software testing.

Never forget a test

Testing is the process of evaluating a system or its component(s) with the intent to find whether it satisfies the specified requirements or not. Testing is executing a system in order to identify any gaps, errors, or missing requirements contrary to the actual requirements. This tutorial will give you a basic understanding of software testing, its types, methods, levels, and other related terminologies.

Code that is not tested can’t be trusted

Bad reputation

“Testing is Too Expensive”: Pay less for testing during software development => pay more for maintenance or correction later. Early testing saves both time and cost in many aspects. However, reducing the cost without testing may result in improper design of a software application, rendering the product useless.

“Testing is Time-Consuming”: Testing is never a time-consuming process. However diagnosing and fixing the errors identified during proper testing is a time-consuming but productive activity.

“Only Fully Developed Products are Tested”: No doubt, testing depends on the source code but reviewing requirements and developing test cases is independent from the developed code. However, iterative or incremental approaches to a development life cycle model may reduce the requirement of testing on the fully developed software.

“Complete Testing is Possible”: It becomes an issue when a client or tester thinks that complete testing is possible. It is possible that all paths have been tested by the team but occurrence of complete testing is never possible. There might be some scenarios that are never executed by the test team or the client during the software development life cycle and may be executed once the project has been deployed.

“A Tested Software is Bug-Free”: No one can claim with absolute certainty that a software application is 100% bug-free even if a tester with superb testing skills has tested the application.

“Testers are Responsible for Quality of Product”: It is a very common misinterpretation that only testers or the testing team should be responsible for product quality. Testers’ responsibilities include the identification of bugs to the stakeholders and then it is their decision whether they will fix the bug or release the software. Releasing the software at the time puts more pressure on the testers, as they will be blamed for any error.

“Test Automation should be used wherever possible to Reduce Time”: Yes, it is true that Test Automation reduces the testing time, but it is not possible to start test automation at any time during software development. Test automaton should be started when the software has been manually tested and is stable to some extent. Moreover, test automation can never be used if requirements keep changing.

Basic

This standard deals with the following aspects to determine the quality of a software application:

Quality model

External metrics

Internal metrics

Quality in use metrics

This standard presents some set of quality attributes for any software such as:

Functionality

Reliability

Usability

Efficiency

Maintainability

Portability

Functional Testing

This is a type of black-box testing that is based on the specifications of the software that is to be tested. The application is tested by providing input and then the results are examined that need to conform to the functionality it was intended for. Functional testing of a software is conducted on a complete, integrated system to evaluate the system’s compliance with its specified requirements.

There are five steps that are involved while testing an application for functionality:

The determination of the functionality that the intended application is meant to perform.

The creation of test data based on the specifications of the application.

The output based on the test data and the specifications of the application.

The writing of test scenarios and the execution of test cases.

The comparison of actual and expected results based on the executed test cases.

An effective testing practice will see the above steps applied to the testing policies of every organization and hence it will make sure that the organization maintains the strictest of standards when it comes to software quality.

Unit Testing

This type of testing is performed by developers before the setup is handed over to the testing team to formally execute the test cases. Unit testing is performed by the respective developers on the individual units of source code assigned areas. The developers use test data that is different from the test data of the quality assurance team.

The goal of unit testing is to isolate each part of the program and show that individual parts are correct in terms of requirements and functionality.

Limitations of Unit Testing:

Testing cannot catch each and every bug in an application. It is impossible to evaluate every execution path in every software application. The same is the case with unit testing.

There is a limit to the number of scenarios and test data that a developer can use to verify a source code. After having exhausted all the options, there is no choice but to stop unit testing and merge the code segment with other units.

Integration Testing

Integration testing is defined as the testing of combined parts of an application to determine if they function correctly. Integration testing can be done in two ways: Bottom-up integration testing and Top-down integration testing.

Bottom-up integration: This testing begins with unit testing, followed by tests of progressively higher-level combinations of units called modules or builds.

Top-down integration: In this testing, the highest-level modules are tested first and progressively, lower-level modules are tested thereafter.

In a comprehensive software development environment, bottom-up testing is usually done first, followed by top-down testing. The process concludes with multiple tests of the complete application, preferably in scenarios designed to mimic actual situations.

System Testing

System testing tests the system as a whole. Once all the components are integrated, the application as a whole is tested rigorously to see that it meets the specified Quality Standards. This type of testing is performed by a specialized testing team.

System testing is important because of the following reasons:

System testing is the first step in the Software Development Life Cycle, where the application is tested as a whole.

The application is tested thoroughly to verify that it meets the functional and technical specifications.

The application is tested in an environment that is very close to the production environment where the application will be deployed.

System testing enables us to test, verify, and validate both the business requirements as well as the application architecture.

Regression Testing

Whenever a change in a software application is made, it is quite possible that other areas within the application have been affected by this change. Regression testing is performed to verify that a fixed bug hasn’t resulted in another functionality or business rule violation. The intent of regression testing is to ensure that a change, such as a bug fix should not result in another fault being uncovered in the application.

Regression testing is important because of the following reasons:

Minimize the gaps in testing when an application with changes made has to be tested.

Testing the new changes to verify that the changes made did not affect any other area of the application.

Mitigates risks when regression testing is performed on the application.

Test coverage is increased without compromising timelines.

Increase speed to market the product.

Acceptance Testing

This is arguably the most important type of testing, as it is conducted by the Quality Assurance Team who will gauge whether the application meets the intended specifications and satisfies the client’s requirement. The QA team will have a set of pre-written scenarios and test cases that will be used to test the application.

More ideas will be shared about the application and more tests can be performed on it to gauge its accuracy and the reasons why the project was initiated. Acceptance tests are not only intended to point out simple spelling mistakes, cosmetic errors, or interface gaps, but also to point out any bugs in the application that will result in system crashes or major errors in the application.

By performing acceptance tests on an application, the testing team will deduce how the application will perform in production. There are also legal and contractual requirements for acceptance of the system.

Alpha Testing

This test is the first stage of testing and will be performed amongst the teams (developer and QA teams). Unit testing, integration testing and system testing when combined together is known as alpha testing. During this phase, the following aspects will be tested in the application:

Spelling Mistakes

Broken Links

Cloudy Directions

The Application will be tested on machines with the lowest specification to test loading times and any latency problems.

Beta Testing

This test is performed after alpha testing has been successfully performed. In beta testing, a sample of the intended audience tests the application. Beta testing is also known as pre-release testing. Beta test versions of software are ideally distributed to a wide audience on the Web, partly to give the program a “real-world” test and partly to provide a preview of the next release. In this phase, the audience will be testing the following:

Users will install, run the application and send their feedback to the project team.

Typographical errors, confusing application flow, and even crashes.

Getting the feedback, the project team can fix the problems before releasing the software to the actual users.

The more issues you fix that solve real user problems, the higher the quality of your application will be.

Having a higher-quality application when you release it to the general public will increase customer satisfaction.

Non-Functional Testing

This section is based upon testing an application from its non-functional attributes. Non-functional testing involves testing a software from the requirements which are nonfunctional in nature but important such as performance, security, user interface, etc.

Some of the important and commonly used non-functional testing types are discussed below.

Performance Testing

It is mostly used to identify any bottlenecks or performance issues rather than finding bugs in a software. There are different causes that contribute in lowering the performance of a software:

Network delay

Client-side processing

Database transaction processing

Load balancing between servers

Data rendering

Performance testing is considered as one of the important and mandatory testing type in terms of the following aspects:

Speed (i.e. Response Time, data rendering and accessing)

Capacity

Stability

Scalability

Performance testing can be either qualitative or quantitative and can be divided into different sub-types such as Load testing and Stress testing.

Load Testing

It is a process of testing the behavior of a software by applying maximum load in terms of software accessing and manipulating large input data. It can be done at both normal and peak load conditions. This type of testing identifies the maximum capacity of software and its behavior at peak time.

Most of the time, load testing is performed with the help of automated tools such as Load Runner, AppLoader, IBM Rational Performance Tester, Apache JMeter, Silk Performer, Visual Studio Load Test, etc.

Virtual users (VUsers) are defined in the automated testing tool and the script is executed to verify the load testing for the software. The number of users can be increased or decreased concurrently or incrementally based upon the requirements.

Stress Testing

Stress testing includes testing the behavior of a software under abnormal conditions. For example, it may include taking away some resources or applying a load beyond the actual load limit.

The aim of stress testing is to test the software by applying the load to the system and taking over the resources used by the software to identify the breaking point. This testing can be performed by testing different scenarios such as:

Shutdown or restart of network ports randomly

Turning the database on or off

Running different processes that consume resources such as CPU, memory, server, etc.

Usability Testing

Usability testing is a black-box technique and is used to identify any error(s) and improvements in the software by observing the users through their usage and operation.

According to Nielsen, usability can be defined in terms of five factors, i.e. efficiency of use, learn-ability, memory-ability, errors/safety, and satisfaction. According to him, the usability of a product will be good and the system is usable if it possesses the above factors.

Nigel Bevan and Macleod considered that usability is the quality requirement that can be measured as the outcome of interactions with a computer system. This requirement can be fulfilled and the end-user will be satisfied if the intended goals are achieved effectively with the use of proper resources.

Molich in 2000 stated that a user-friendly system should fulfill the following five goals, i.e., easy to Learn, easy to remember, efficient to use, satisfactory to use, and easy to understand.

In addition to the different definitions of usability, there are some standards and quality models and methods that define usability in the form of attributes and sub-attributes such as ISO-9126, ISO-9241-11, ISO-13407, and IEEE std.610.12, etc.

UI vs Usability Testing

UI testing involves testing the Graphical User Interface of the Software. UI testing ensures that the GUI functions according to the requirements and tested in terms of color, alignment, size, and other properties.

On the other hand, usability testing ensures a good and user-friendly GUI that can be easily handled. UI testing can be considered as a sub-part of usability testing.

Security Testing

Security testing involves testing a software in order to identify any flaws and gaps from security and vulnerability point of view. Listed below are the main aspects that security testing should ensure:

Confidentiality

Integrity

Authentication

Availability

Authorization

Non-repudiation

Software is secure against known and unknown vulnerabilities

Software data is secure

Software is according to all security regulations

Input checking and validation

SQL insertion attacks

Injection flaws

Session management issues

Cross-site scripting attacks

Buffer overflows vulnerabilities

Directory traversal attacks

Portability Testing

Portability testing includes testing a software with the aim to ensure its reusability and that it can be moved from another software as well. Following are the strategies that can be used for portability testing:

Transferring an installed software from one computer to another.

Building executable (.exe) to run the software on different platforms.

Portability testing can be considered as one of the sub-parts of system testing, as this testing type includes overall testing of a software with respect to its usage over different environments. Computer hardware, operating systems, and browsers are the major focus of portability testing. Some of the pre-conditions for portability testing are as follows:

Software should be designed and coded, keeping in mind the portability requirements.

Unit testing has been performed on the associated components.

Integration testing has been performed.

Test environment has been established.

Test Plan

A test plan outlines the strategy that will be used to test an application, the resources that will be used, the test environment in which testing will be performed, and the limitations of the testing and the schedule of testing activities. Typically the Quality Assurance Team Lead will be responsible for writing a Test Plan.

A test plan includes the following:

Introduction to the Test Plan document

Assumptions while testing the application

List of test cases included in testing the application

List of features to be tested

What sort of approach to use while testing the software

List of deliverables that need to be tested

The resources allocated for testing the application

Any risks involved during the testing process

A schedule of tasks and milestones to be achieved

Test Scenario

It is a one line statement that notifies what area in the application will be tested. Test scenarios are used to ensure that all process flows are tested from end to end. A particular area of an application can have as little as one test scenario to a few hundred scenarios depending on the magnitude and complexity of the application.

The terms ‘test scenario’ and ‘test cases’ are used interchangeably, however a test scenario has several steps, whereas a test case has a single step. Viewed from this perspective, test scenarios are test cases, but they include several test cases and the sequence that they should be executed. Apart from this, each test is dependent on the output from the previous test.

Test Case

Test cases involve a set of steps, conditions, and inputs that can be used while performing testing tasks. The main intent of this activity is to ensure whether a software passes or fails in terms of its functionality and other aspects. There are many types of test cases such as functional, negative, error, logical test cases, physical test cases, UI test cases, etc.

Furthermore, test cases are written to keep track of the testing coverage of a software. Generally, there are no formal templates that can be used during test case writing. However, the following components are always available and included in every test case:

Test case ID

Product module

Product version

Revision history

Purpose

Assumptions

Pre-conditions

Steps

Expected outcome

Actual outcome

Post-conditions

Many test cases can be derived from a single test scenario. In addition, sometimes multiple test cases are written for a single software which are collectively known as test suites.
