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

	Fixie http://fixie.github.io/	Kiwi https://github.com/kiwi-bdd/Kiwi
Programming language	.NET	Swift
Category	Unit Testing	Unit Testing
General info	Fixie is a .NET test framework similar to NUnit and xUnit Fixie allows test methods to be created and executed like other test frameworks, but takes a takes a conventions-based approach, which is a benefit as we do not need to use attributes to mark classes and methods as tests	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 fixie is an xUnit type testing framework	Yes Kiwi is an xUnit style framework
Client-side Allows testing code execution on the client, such as a web browser	Yes You can unit test front-end components of youra pplications with fixie	Yes You can test front-end components with kiwi
Server-side Allows testing the bahovior of a server-side code	Yes You can unit test back-end components of your applications with fixie	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 Yes, fixie has fixture methods for setting up tests and at the end of tests to destroy them
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.	N/A	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.	N/A	Yes through the beforeAll(aBlock) and afterAll(aBlock) functions.
Licence Licence type governing the use and redistribution of the software	MIT License	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)	N/A	Yes Kiwi has inbuilt support for stubs and mocks,including null mocks, class mocks, protocol mocks
Grouping Allows organizing tests in groups	Yes You can group tests into suites	Yes Kiwi uses the block syntax in iOS to define groups of assertions and share setup state between collections of tests
