JUnit vs Selenium comparison of testing frameworks
What are the differences between JUnit and Selenium?

	JUnit https://junit.org/junit5/	Selenium https://pypi.org/project/selenium/
Programming language	Java	Python
Category	Unit Testing, Regression Testing	Web Automation
General info	JUnit is an open source Unit testing framework for java JUnit is useful for developers to write and run repeatable tests. JUnit has been crucial in the development of test driven development and is partof the xUnit family of unit testing frameworks	Selenium is an open source tool used to test web applications Selenium is a powerful testing tool which can send standard Python commands to different browsers, despite variations in browser design. It also provides extensions to emulate user interaction with browsers, a distribution server for scaling browser allocation, and the infrastructure for implementations of the W3C WebDriver specification that lets you write interchangeable code for all major web browsers
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes It is an instance of the xUnit architecture for unit testing frameworks.	No
Client-side Allows testing code execution on the client, such as a web browser	Yes You can test front-end components such as individual classes and functions that create the front-end	Yes It is primarily a browser automation tool which tests front-end components and functionality
Server-side Allows testing the bahovior of a server-side code	Yes You can test classes and functions that compose the back-end such as database connections and so on	Yes It can perform Unit tests and can test various components and behaviours in the backend using a BDD or TDD approach
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes JUnit contains a setUp() method, which runs before every test invocation and a tearDown() method, which runs after every test method.	Yes By writing your Selenium WebDriver tests in PyTest, this gives you access to Pytest's powerful fixture model
Group fixtures Allows defining a fixed, specific states of data for a group of tests (group-fixtures). This ensures specific environment for a given group of tests.	Yes You can use setUp() and tearDown() inbuilt functions as group fixtures.	Yes One can group fixtures if accessing Pytest's fixture model
Generators Supports data generators for tests. Data generators generate input data for test. The test is then run for each input data produced in this way.	You can use JUnit-quickcheck to generate test data	Yes By using a library such as Faker or Fake-factory

Mocks Mocks are objects that simulate the behavior of real objects. Using mocks allows testing some part of the code in isolation (with other parts mocked when needed)	JUnit does not support mocking internally but you can use a mock framework like Mockito to generate mock objects.	Yes It includes support for mocking
Grouping Allows organizing tests in groups	Yes In JUnit you can create a test suite that bundles a few unit test cases and runs them together. You use both @RunWith and @Suite annotation are used to run the suite test.	Yes By using the TestNG feature with which we can create groups and maintain them easily
