Programming language	JavaScript	JavaScript
Category	Unit Testing	Unit 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	A Unit Testing framework focused on simplicity This is a Unit test framwork especially designed for the React.JS, Babel, TypeScript, Node, React, Angular and Vue projects. It usually worked with Enzyme(Integration testing)
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	No
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 easily test methods, properties, UI element actions and other front-end functionalities
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 Back-end server behaviour also can be tested with Jest much in the same way as the front-end tests.
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 Fixtures are supported, Jest has many helper functions such as: BeforeEach and afterEach If you have some work you need to do repeatedly for many tests, beforeAll and afterAll if you only need to do setup once, at the beginning of a file.
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 Jest supports 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.		N/A
Licence Licence type governing the use and redistribution of the software	MIT License	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	Jest uses a custom resolver for imports in your tests making it simple to mock any object outside of your test’s scope. You can use mocked imports with the rich Mock Functions API to spy on function calls with readable test syntax.
Grouping Allows organizing tests in groups	Yes You can use the QUnit.module() function to group tests together	Yes You can declare as many test suites as you want. Grouping of tests together is done using a describe block
