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

	Kotest https://github.com/kotest/kotest	Minitest https://github.com/seattlerb/minitest
Programming language	Kotlin	Ruby
Category	Unit Testing	Unit Testing
General info	kotest is a powerful, elegant and flexible test framework for Kotlin, formerly known as kotlintest Kotest has excellent support for data driven testing or table driven testing where it has the ability to quickly rerun the same test over and over with a predefined set of inputs and expected values	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 You can test front-end components with kotest	No
Server-side Allows testing the bahovior of a server-side code	Yes Yes, you can test back-end components with kotest	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 kotest contains fixtures, that is the setup / teardown functions	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 kotest has group fixtures available	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.	N/A

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 You can use a third party library like mockk to create mocks	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 create test suites with kotest	Yes Allows grouping by nested Ruby classes. RSpec-like "context" method is available for spec syntax through the minitest-spec-context extension gem
