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

	Minitest https://github.com/seattlerb/minitest	ExUnit https://hexdocs.pm/ex_unit/ExUnit.html
Programming language	Ruby	Elixir
Category	Unit Testing	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.	Unit testing framework for Elixir. Elixir comes bundled with ExUnit allowing developers to use all elixir features without compromising unit tests. It uses a TDD workflow, and shows one message per test
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 xUnit has the ExUnit framework as an instance
Client-side Allows testing code execution on the client, such as a web browser	No	Yes Front-end code can be tested using ExUnit, Phoenix front-end framework for Elixir uses ExUnit as the default testing framework
Server-side Allows testing the bahovior of a server-side code	Yes You can test various back-end components	Yes ExUnit tests backend code. Typically Unit tests will be written not to interact with the browser, but with ExUnit you can test whichever part of your application
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 ExUnit has a library called ExUnitFixtures fixtures are functions that are run before a test is run to setup the test environment or provide the test with data
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 Group fixures are possible with this library
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.		Yes Generators are found in the StreamData module
Licence Licence type governing the use and redistribution of the software	MIT License	Apache License 2.0
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	Yes Mocks are available for use with ExUnit through the Mock module. Also available through the use of third party libraries like mecktest
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 Using the 'describe' function which goups tests together. Every describe block recieves a name which is used as a prefix for upcoming tests
