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

	Kiwi https://github.com/kiwi-bdd/Kiwi	PHPSpec https://www.phpspec.net/en/stable/
Programming language	Swift	PHP
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.	PhpSpec is a testing tool based on the concept of emergent design using specification PhpSpec is a tool to use at the spec level or SpecBDD, a type of BDD; It's process generates code for you and guides you through the SpecBDD process through the command line
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes Kiwi is an xUnit style framework	No
Client-side Allows testing code execution on the client, such as a web browser	Yes You can test front-end components with kiwi	Yes By testing your PHP classes that run your front-end
Server-side Allows testing the bahovior of a server-side code	Yes You can test back-end components with kiwi	Yes You can use PHPSpec to test your PHP classes that run your back-end
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test		Yes You can define fixtures
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 You can define 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.	Yes There are methods that act as generators
Licence Licence type governing the use and redistribution of the software	Proprietary, Open source	Free
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 It has built in support for Mocks
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	In PHPspec, you can group specification files by a certain namespace in a suite
