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

	QUnit https://qunitjs.com/	Intern https://github.com/theintern/intern
Programming language	JavaScript	JavaScript
Category	Unit Testing	Unit Testing, Functional 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	Intern is minimal test system for JavaScript designed to write and run consistent. Intern is a complete test system for JavaScript designed to help you write and run consistent, high-quality test cases for your JavaScript libraries and applications. Using Intern we can write tests in JavaScript and TypeScript using any style like TDD, and BDD. Intern can run unit tests in most browsers that support ECMAScript
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 Intern is a complete test system for JavaScript It Runs in the browser and can test any front-end component and functionality
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 Since it is a complete testing system that can test any type of JavaScript code, it can test server-side behaviour and components as well
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.	N/A
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	N/A
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.
Licence Licence type governing the use and redistribution of the software	MIT License	FreeBSD 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	Intern uses the Dojo Toolkit’s AMD loader. To mock, you should be able to just use the standard AMD 'map' feature, else you can use third party libraries like sinon.js
Grouping Allows organizing tests in groups	Yes You can use the QUnit.module() function to group tests together	Yes You can group tests into Suites which may be specified as file paths or using glob expressions, there is typically one top-level suite per module.
