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

	QUnit https://qunitjs.com/	JUnit https://junit.org/junit5/
Programming language	JavaScript	Java
Category	Unit Testing	Unit Testing, Regression Testing
General info	QUnit is a JS Unit testing framework. QUnit is especially useful for regression testing of jQuery, jQuery UI and jQuery Mobile projects	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
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes Yes, it is a xUnit style framework	Yes It is an instance of the xUnit architecture for unit testing frameworks.
Client-side Allows testing code execution on the client, such as a web browser	Yes QUnit is commonly used by jQuery, jQuery UI and jQuery Mobile It can test front-end components and functionality	Yes You can test front-end components such as individual classes and functions that create the front-end
Server-side Allows testing the bahovior of a server-side code	Yes Qunit can test any JavaScript code(including itself), this includes server-side components and functionality. Supports NodeJs	Yes You can test classes and functions that compose the back-end such as database connections and so on
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes By using the qunit-fixture element which is a container for some HTML that your tests can assert against.	Yes JUnit contains a setUp() method, which runs before every test invocation and a tearDown() method, which runs after every test method.
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 group fixtures together with QUnit	Yes You can use setUp() and tearDown() inbuilt functions as group fixtures.
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
Licence Licence type governing the use and redistribution of the software	MIT License
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)	You can use third party libraries like jQuery's Mockjax plugin	JUnit does not support mocking internally but you can use a mock framework like Mockito to generate mock objects.
Grouping Allows organizing tests in groups	Yes You can use the QUnit.module() function to group tests together	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.
