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

	Minitest https://github.com/seattlerb/minitest	teenytest https://github.com/testdouble/teenytest
Programming language	Ruby	JavaScript
Category	Unit Testing
General info	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.	Teenytest is a simple, zero-config test runner for NodeJS Teenytest's CLI will run tests with zero public-API and zero configuration
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes MiniTest is an xUnit style framework in that is has assertion functions in the style of xUnit/TDD	Yes It supports xUnit output
Client-side Allows testing code execution on the client, such as a web browser	No	No
Server-side Allows testing the bahovior of a server-side code	Yes You can test various back-end components	Yes Teenytest tests database connections and other server-side components and behaviour
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes Minitest supports test fixture functions	Yes It provides fixtures with the methods beforeAll(),afterEach() and afterAll()beforeAll() creates the browser and gives you a newPage() globalafterEach() will close any pages you created with newPage()afterAll() closes the browser
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 Minitest has group fixtures	Yes Teeny test supports grouping of 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.
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)	Yes Mocking is available through the Minitest::Mock class which is a simple and clean mock object framework	N/A
Grouping Allows organizing tests in groups	Yes Allows grouping by nested Ruby classes. RSpec-like "context" method is available for spec syntax through the minitest-spec-context extension gem	Yes Grouping is supported through nested tests in which any object can contain any combination of hooks, test functions, and additional sub-test objects.
