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

	JUnit https://junit.org/junit5/	Kiwi https://github.com/kiwi-bdd/Kiwi
Programming language	Java	Swift
Category	Unit Testing, Regression Testing	Unit Testing
General info	JUnit is an open source Unit testing framework for java JUnit is useful for developers to write and run repeatable tests. JUnit has been crucial in the development of test driven development and is partof the xUnit family of unit testing frameworks	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.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes It is an instance of the xUnit architecture for unit testing frameworks.	Yes Kiwi is an xUnit style framework
Client-side Allows testing code execution on the client, such as a web browser	Yes You can test front-end components such as individual classes and functions that create the front-end	Yes You can test front-end components with kiwi
Server-side Allows testing the bahovior of a server-side code	Yes You can test classes and functions that compose the back-end such as database connections and so on	Yes You can test back-end components with kiwi
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes JUnit contains a setUp() method, which runs before every test invocation and a tearDown() method, which runs after every test method.
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 You can use setUp() and tearDown() inbuilt functions as group fixtures.	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
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.	You can use JUnit-quickcheck to generate test data	Yes through the beforeAll(aBlock) and afterAll(aBlock) functions.
Licence Licence type governing the use and redistribution of the software		Proprietary, Open source
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)	JUnit does not support mocking internally but you can use a mock framework like Mockito to generate mock objects.	Yes Kiwi has inbuilt support for stubs and mocks,including null mocks, class mocks, protocol mocks
Grouping Allows organizing tests in groups	Yes In JUnit you can create a test suite that bundles a few unit test cases and runs them together. You use both @RunWith and @Suite annotation are used to run the suite test.	Yes Kiwi uses the block syntax in iOS to define groups of assertions and share setup state between collections of tests
