Best Selenium Frameworks for Automating Unit Testing for Web Applications

Selenium is the most preferred tool of all times when it comes to automating web applications. Selenium supports many unit testing Frameworks based on multiple programming languages like JAVA, C#, PHP, Ruby, Perl, JavaScript, Python; used for executing test scripts on web applications on platforms like Windows, MacOS, Linux, etc. Any successful automation process is based on powerful Testing Frameworks that help the QA team optimize their agile processes, reduce maintenance cost, testing efforts, and provide a higher return on investment.

Selenium Framework and Unit Testing

What is Unit Testing?

Before moving on to the framework in Selenium, let us discuss what Unit Testing means. The term is simpler than what we think it is. It is simply a process where the developer breaks down the entire web application code into smaller units and tests them separately. This process of breaking and testing each unit is often known as Unit testing. Unit testing is the first stage of Web app testing in every Software Development Life Cycle process (SDLC). Some developers skip unit testing which later leads to higher bugs and other problems at the later stages. Early detection of errors always saves users from facing any serious issues later. It is performed before integration testing and ensures that every feature of the app functions as planned. Although unit testing can be performed manually, it delays the final release timelines at extreme levels.

  • Allow reviewing the test cases and rewrite them in case there are any glitches
  • Understanding if every code line is within the scope and as intended
  • Helping in executing the code with the help of Selenium Grid

Selenium Automation Framework

What is a framework in selenium? Usually, if users place the code and data in the same place, they can’t reuse or read them so, they use frameworks. Selenium Framework is a code structure that eases code maintenance, code readability, code usage, re-usage, and allows multiple users to work on the same code. Based on the programming language, developers choose a particular Unit Testing Framework. The strategy goes like this — Developer develops the application code; a unit test is created simultaneously for the same code, and the present unit test automatically runs via a chosen Unit test framework on already developed code. It parallelly ensures that the new code is not breaking the earlier one. The entire process is automatic, so it creates more space for the developers to focus on developing new code rather than wasting time manually testing the earlier written code.

  • Maintain a Separate group system for the test cases.
  • Prioritize which test case should run first in the series.
  • Managing tests in such a way that the same test can run multiple times with different data sets
  • Capable of reading the content from external sources, for example, Excel Files, etc.
  • Saves time by allowing multiple tests to run parallelly
  • Creates text logs to track changes that happened while the tests were running
  • Report generation to analyze test results for each test execution
  • PyTest is the second most used open-source Unit Testing framework for Python-based applications, supporting API and complex functional testing. Additionally, PyTest has eased testing databases, UIs and APIs. Its ability to integrate easily with third-party plugins and assert writing has made it a popular choice among the projects like Mozilla and Dropbox.
  • It was introduced to overcome the shortcomings of the MSTest framework. It is again an open-source framework written in C# language. This XUnit component can test any type of .Net application. You can differentiate your codes from unit tests by simply adding a class library, which means it doesn’t need a specific project type. However, developers will need an in-depth knowledge of the .Net frameworks to be able to reap the maximum benefits of this framework.

E.Selenium Framework for unit test automation in Perl:

Perl is a general-purpose language developed mainly for text manipulation. It is also used for web and GUI development, system administration, etc., in recent times. Larry Wall created this language; it is very stable and works in a cross-platform scenario. This language is a bit complicated to learn and implement; that is why there are not many unit testing frameworks available relating to Perl. However, PerlUnit is a savior in this game.

Conclusion

Unit testing helps the QA team create a competitive end product and ensures its faster release to the market. It also confirms that every unit of the code is thoroughly tested as soon as it is created. In this way, the chances of critical bug issues are reduced and do not impact the later stages of SDLC. There are language-based frameworks for JAVA, C#, PHP, Ruby, JavaScript, Python, available for testing web apps that easily integrate with Selenium Automation Testing. Developers can choose from various options available based on what language the web apps are built-in.
