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

	Kiwi https://github.com/kiwi-bdd/Kiwi	Peridot http://peridot-php.github.io/
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.	Peridot is a lightweight, extensible testing framework for PHP It features an event-driven architecture that allows testers to easily customize the framework via plugins and reporters, and uses the 'describe-it', syntax making the testing language clear and readable
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 Front-end components can be tested with Peridot
Server-side Allows testing the bahovior of a server-side code	Yes You can test back-end components with kiwi	Yes Back-end componets and behaviours can be tested as small units
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test		Yes Peridot has several methods that allow one to create and 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 There are methods to create group fixtures in Peridot
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.	N/A
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	Peridot does not include mocking out of the box but there are some great tools like 'Mockery' and 'Prophecy' which Peridot intergrates very well with
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 By use of describe and context blocks and it has a Runner which is responsible for running a given Suite.
