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

	Kiwi https://github.com/kiwi-bdd/Kiwi	Sleipnir https://github.com/railsware/Sleipnir
Programming language	Swift	Swift
Category	Unit Testing	Unit Testing, Acceptance 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.	Sleipnir is a BDD-style framework for Swift Sleipnir is a pure Swift BDD testing framework inspired by cedar, that is not dependent on NSObject, and does not use XCTest. Sleipnir has nice command line output and support for custom test reporters and other features, like seeded random tests invocation, focused and excluded examples/groups
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes Kiwi is an xUnit style framework	N/A
Client-side Allows testing code execution on the client, such as a web browser	Yes You can test front-end components with kiwi	Yes You can test front-end behaviour by defining specifications for classes, objects and functions
Server-side Allows testing the bahovior of a server-side code	Yes You can test back-end components with kiwi	Yes You can test back-end behaviour by defining specifications for classes, objects and functions in the 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 Fixtures are available by using beforeEach{ } and afterEach{ } to setup the test parameters
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 Group fixtures are available through the beforeAll{} and afterAll{} blocks to setup 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.	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	Yes Yes, developers can create mock objects with sleipnir using a third party library like Cuckoo.
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 You can declare example groups with Slepnir
