Test::Unit vs Minitest comparison of testing frameworks
What are the differences between Test::Unit and Minitest?

	Test::Unit https://test-unit.github.io/	Minitest https://github.com/seattlerb/minitest
Programming language	Ruby	Ruby
Category	Unit Testing, Intergration Testing	Unit Testing
General info	Test::Unit is a unit testing framework for Ruby Test::Unit is an implementation of the xUnit testing framework for ruby which is used for Unit Testing. However Test::Unit has been left in the standard library to support legacy test suites therefore if you are writing new test code use Minitest instead of Test::Unit	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.	Yes test-unit is a xUnit family unit testing framework for Ruby	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	It could have tested some front-end components but its now legacy hence wouldn't work with the many new front-end components	No
Server-side Allows testing the bahovior of a server-side code	Yes	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	Yes Fixture methods are available through its ClassMethods Module	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.	Yes Group fixture methods are supported	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.	No
Licence Licence type governing the use and redistribution of the software	LGPLv2.1, Ruby Licence	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)	No	Yes Mocking is available through the Minitest::Mock class which is a simple and clean mock object framework
Grouping Allows organizing tests in groups	No	Yes Allows grouping by nested Ruby classes. RSpec-like "context" method is available for spec syntax through the minitest-spec-context extension gem
