Why critical Thinking is necessary for Software Testers?

Testing is not just about applying the fundamentals of testing, testing process or testing types. Yes it is very essential and important to understand the above but as we have seen all concepts when implemented or executed need more than just steps or procedures. The most important part in software testing is the way a tester puts the above concepts and then starts executing test cases with a thought process that will validate all kinds of scenarios. This basically can be summarized as Critical Thinking.

We implement “Critical Thinking” concept in our everyday lives as well for example before leaving from home to go to work we all think of alternatives for reaching the work faster, as well as make decisions on jumping signals, or overtake a person from the wrong side. The above though scary we still execute it based on our mindset and decisions.

How does Critical Thinking change the way a Tester works:

I think you agree on the part that why critical thinking is a must but let’s sees the same by practically implementing and putting it in action. Here we will be using a Test Case which is checking the functionality of “Attachments during sending emails”.

Typically the Test Case description would look like:

Testing the different ways of attaching images, documents, wav files while creating/sending emails.

The steps for the same will be:

1.    Test step #1 Click on New E-mail

·       Expected result: New E-mail option will open in new browser/tab

2.    Test Step #2 Enter mandatory fields

a.     Expected Result: the page highlights all mandatory fields in a different color and on not entering the fields the validation is done on the screen with an appropriate message.

3.    Test Step #3 Adding an attachment

a.     Expected result: the attachment is successfully added and the email is sent.

Now to execute the above test case for Step 3 we can come across multiple data types and situations if the tester has really thought this through correctly. I am listing down a few here:

# Data type: Attaching a word, excel, ppt, any wav files ( music), any images ( JPG, PNG…)

# Scenario 1: internet connectivity

# Scenario 2: restriction of file size

# Scenario 3: restriction for number of people we can send this email with attached

All the above scenarios and data types are part of how you think critically as a tester in executing the test cases. I hope the above content was usual if you are already working as a tester or thinking of joining the software testing industry.

Why Swift Is Taking Control In IOS App Development?

Programming languages keep on entering the world of technology to ease the way developers write code as well as solve critical functionalities through libraries and as a result we always have one or the other language supersede the other. We have see how Kotlin took over from Java as the official programming language for Android Mobile applications and now we will see how introduction of Swift, language developed by Google took over from Objective-C. People say swift brings out a lot of objective without the traditional “C”. We will see here in details what they mean by comparing the differences and how Swift as really made it easier for IOS appdevelopers to write code as well as maintain it.

Why did the need Arise?

So why another programming language for IOS App Development. So let’s quickly review what Objective-C kind of made developers move so easily:

1) Syntax of objective-C – for developers who have used this they will agree to the same. Objective-C’s syntax as well as use of [ ], @, *, **, is difficult if a developer is moving from another programming language to Objective-C

2) Lengthy – the code in Objective-C is lengthier than the newer programming language

3) Memory Management in objective-C

So now let’s look at how Swift does this better with and what else is good about Swift?

Swift was introduced in 2014 by Apple, and thereafter started getting popular very quickly because of its easily readable syntax as compared to objective – C and also easy of writing code. But its very important for developers to actually first learn Application development in Objective-C without moving directly to Swift. This will help them understand and upgrade faster to Swift rather than directly learning the newer language.

So lets look at the dynamic features of Swift to understand its popularity:

1) Clean Syntax – This is the biggest advantage of using Swift; the syntax is so clean and concise and it is easier to read and write code. We no longer have to use semi colons or parenthesis to work with loops. Swift works with plain English rather than complex use of punctuations which makes a developers world miserable. This functionality helps any developers having exposure with other programming languages easily migrate into Swift.

2) Fixes Code as you write: With Swift you don’t need to wait for run time compilation errors to rectify bad programming errors; you can fix it as you write code.

3) Less Lines of Code: Because of the ease of syntax and support of playing with text strings and data Swift provides lesser lines of code than Objective-C.

4) Fast Paced: With Swift we can see the commitment of Apple to improve the speed at which the Application logic is run. We have seen a lot of Application crashes under Objective-C which has been reduced considerably with Swift.

So by now, you all might be inquisitive to start working on Swift and get going. For all developers that have already implemented applications in Objective-C don’t worry; here are options that will help you easily get you on boarded with Swift. Switching to Swift from objective-C for an already implemented/executing project is doable and this activity is called bridging which is done by header files but this depends on the size of the project.

Secondly, XCode helps create the bridging file to ensure the code is compiled and executed correctly.

I hope this article was useful for users that are either curious to know about swift and/or for users that are planning to switch. TOPS Technologies provides training on latest versions of IOS with Swift with hands on practical and project exposure to make your learning easy and fast.
