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.

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
