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

	Turnip https://github.com/jnicklas/turnip	Sleipnir https://github.com/railsware/Sleipnir
Programming language	Ruby	Swift
Category	Acceptance Testing, Integration Testing	Unit Testing, Acceptance Testing
General info	Turnip is a Gherkin extension for RSpec Turnip is an open source Ruby gem that provides a platform for acceptance tests.It combines Gherkin, a language defined by the Cucumber Behavior-Driven Development (BDD) tool to express requirements, and RSpec, an open source BDD tool for Ruby developers.	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.	No	N/A
Client-side Allows testing code execution on the client, such as a web browser	Yes Turnip can perform end-to-end tests therefore test front-end components and functionality	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 Turnip is used to test server-side behaviour and components	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	No	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.	No	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.	No	N/A
Licence Licence type governing the use and redistribution of the software	MIT License	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 By intergrating with RSpec turnip has access to the rspec-mocks gem	Yes Yes, developers can create mock objects with sleipnir using a third party library like Cuckoo.
Grouping Allows organizing tests in groups	Yes Turnip Integrates directly into your RSpec test suite which allows declaring example groups and contexts.	Yes You can declare example groups with Slepnir
