Java has always been used as the first language for developing dynamic and robust web applications. It provides the flexibility that developers need to create effective web apps. So, when it comes to unit testing of Java-based web apps, there are minimal Unit Test Frameworks available, such as:
JUnit has always been the first choice of developers to automate unit testing of a java-based application. It was developed by Erich Gamma and Kent Beck as an instance of xUnit. JUnit was specially developed for scripting and performing repetitive test cases. But, it can also be utilized to automate testing of web applications by integrating it with selenium webdriver.
TestNG is an open-source testing framework created by Cedric Beust. TestNG covers a wide range of test categories which includes unit, functional, end-to-end, integration. It is being widely used by Java developers to unit test developed web applications. It was designed to overcome the competencies of JUnit. That’s why it is more robust, reliable, and featureful than JUnit. It provides developers with various functionalities, such as grouping, sequencing, and parameterizing, which allow them to create more flexible test cases while eliminating the drawbacks of JUnit and to automate unit tests.
PyTest is an excellent python-based automation testing framework that can be used for all types of software testing. Apart from being an open-source Unit Test Framework, it is easy to learn and implement on any workstation. With features like assert writing, PyTest has become the first choice of major projects on the internet, such as Dropbox, Mozilla, etc.
Also known as UnitTest – PyUnit is the standard unit testing framework for Python-based applications. In PyUnit, the base class ‘TestCase’ is used for all the assertion methods, code cleanup, and set up routines. Other than that, you can also use the load methods and the ‘TestSuite’ class for grouping and loading of test cases. And if you use them together, then you can build customized test runners.
MSTest comes with an in-built testing framework provided by Microsoft known as Visual Studio. So, it doesn’t require additional downloading or installation on your system, as you will get it out of the box in your IDE. It is particularly used to run tests on .NET applications. And if you’re using TestComplete, then you can easily integrate the MSTest tests in your test scripts and execute them as a part of your testing process.
NUnit is an open-source unit testing framework that is entirely written in C#. It belongs to the xUnit family and can be used for almost every .Net application. Having user-friendly attributes, NUnit offers a simple and easy working process for developers. Moreover, it doesn’t require a specific project type; you can add a class library to differentiate your code from the unit tests.
