Test automation has changed the rules for writing codes and the speed at which codes are tested during the software development life cycle.

Unit Testing is magic in Automated Testing

In the testing cycle, unit testing is one of the first testing processes developers run while creating the application’s source code. Each code is designed and tested in such a way to determine its functionality and performance while the developer creates other codes for the application.

You can imagine how easy it is for developers to get their unit tests running when the entire test cycle is automated before moving to integration testing.

And this is done by Selenium, it made automation testing an easy task. All you need to do is discover the right unit testing framework and test all the modules of your web application. So, let’s take a look at some well-tested and well-matched unit testing automation frameworks that you can integrate with Selenium Test Automation.

 Different Unit testing frameworks for Selenium

1. JUnit

JUnit is an open-source Unit testing framework for Java applications. It is useful for developers to write and run repeatable tests. Developers who follow test-driven methodology must write and run unit tests first before any code.

Once you are writing with code, you should run all tests, and it should pass. Every time any code is added, you need to rerun all test cases and make sure nothing is broken.

JUnit runs tests quickly and identifies the bugs in a separate block for debugging, and this property makes JUnit popular among the rest of the Java frameworks for Selenium.

2. TestNG

TestNG is one of the open-source testing frameworks for Java which covers a broad category of tests and integrates very well with Selenium. It is designed to overcome the limitations of the JUnit framework. It is robust and offers unique features that make it easy for developers to use multiple annotations, test dependencies, grouping, and prioritization.

TestNG lets developers run multiple test cases simultaneously, making the test execution process faster compared to other frameworks. It also handles exceptions automatically, tagging them as failed steps in the test report.

Automation with Selenium WebDriver (Java)


Performing unit tests on source codes is the primary step towards quality assurance that determines the application’s functionality, performance, and security. While the burden is on developers to check each code separately, it greatly helps if the tests are automated. Automation is the key to the challenge, as speed has become the essence of software development.

Apart from Java, multiple frameworks supporting JS, Python, C#, Perl, and Ruby integrate seamlessly with Selenium test automation. The success of the testing cycle is determined by the integration of the appropriate frameworks.
