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

	SimpleTest https://github.com/simpletest/simpletest	Kiwi https://github.com/kiwi-bdd/Kiwi
Programming language	PHP	Swift
Category	Unit Testing, Web Testing	Unit Testing
General info	SimpleTest is a unit test and web test framework for PHP It has JWebUnit style functionality and support for SSL, forms, frames, proxies and basic authentication	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.	No	Yes Kiwi is an xUnit style framework
Client-side Allows testing code execution on the client, such as a web browser	Yes With SimpleTest common but fiddly PHP tasks, such as logging into a site, can be tested easily	Yes You can test front-end components with kiwi
Server-side Allows testing the bahovior of a server-side code	Yes Server-side behaviour can be tested by writing simple unit tests to test functionality and behaviour of single components.	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 It can import fixtures using a mixin like 'given()' 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 It allows grouping of 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.	Yes Simpletest has support for generators	Yes through the beforeAll(aBlock) and afterAll(aBlock) functions.

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 It allows for one to build Mock objects.To create a mock version of a class we need to include the mock object library and run the generator. This will create a clone class which we use to create new instances(objects) in our test cases.	Yes Kiwi has inbuilt support for stubs and mocks,including null mocks, class mocks, protocol mocks
Grouping Allows organizing tests in groups	Yes There are several ways of grouping tests; one is to simply place multiple test cases into a single file, another is to mark any base test cases that should not be run as abstract, Simpletest gives you a couple of options	Yes Kiwi uses the block syntax in iOS to define groups of assertions and share setup state between collections of tests
