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

	Intern https://github.com/theintern/intern	Minitest https://github.com/seattlerb/minitest
Programming language	JavaScript	Ruby
Category	Unit Testing, Functional Testing	Unit Testing
General info	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	Complete suite of testing facilities Minitest is small, fast, and it aims to make tests clean and readable. It supports test-driven development (TDD), behavior-driven development (BDD), mocking, and benchmarking.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes MiniTest is an xUnit style framework in that is has assertion functions in the style of xUnit/TDD
Client-side Allows testing code execution on the client, such as a web browser	Yes Intern is a complete test system for JavaScript It Runs in the browser and can test any front-end component and functionality	No
Server-side Allows testing the bahovior of a server-side code	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	Yes You can test various back-end components
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	N/A	Yes Minitest supports test fixture functions
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.	N/A	Yes Minitest has 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)	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	Yes Mocking is available through the Minitest::Mock class which is a simple and clean mock object framework
Grouping Allows organizing tests in groups	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.	Yes Allows grouping by nested Ruby classes. RSpec-like "context" method is available for spec syntax through the minitest-spec-context extension gem
