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

	Kiwi https://github.com/kiwi-bdd/Kiwi	Minitest https://github.com/seattlerb/minitest
Programming language	Swift	Ruby
Category	Unit Testing	Unit Testing
General info	Kiwi is a Behavior Driven Development library for iOS development The goal behind Kiwi is to provide a BDD library that is simple to setup and use, and create tests that are more readable than what is possible with the bundled test framework.	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 Kiwi is an xUnit style framework	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 kiwi	No
Server-side Allows testing the bahovior of a server-side code	Yes You can test back-end components with kiwi	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 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 kiwi has a beforeEach(aBlock) which is run before every 'it' block in all enclosed contexts. Code that sets up the particular context should go here and afterEach(aBlock) which is run after every it block in all enclosed contexts	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.	Yes through the beforeAll(aBlock) and afterAll(aBlock) functions.
Licence Licence type governing the use and redistribution of the software	Proprietary, Open source	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 Kiwi has inbuilt support for stubs and mocks,including null mocks, class mocks, protocol 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 Kiwi uses the block syntax in iOS to define groups of assertions and share setup state between collections of tests	Yes Allows grouping by nested Ruby classes. RSpec-like "context" method is available for spec syntax through the minitest-spec-context extension gem
