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

	XCTest https://developer.apple.com/documentation/xctest	Turnip https://github.com/jnicklas/turnip
Programming language	Swift	Ruby
Category	Unit Testing, Performance Testing	Acceptance Testing, Integration Testing
General info	XCTest is the default testing framework for unit tests, performance tests, and some level of UI tests for iOS apps. XCTest framework is a testing framework that enables developers write basic unit tests, performance tests, and some level of UI tests for iOS apps.	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.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes Yes, it is an xUnit style framework	No
Client-side Allows testing code execution on the client, such as a web browser	Yes Developers can test individual front-end components with XCTest	Yes Turnip can perform end-to-end tests therefore test front-end components and functionality
Server-side Allows testing the bahovior of a server-side code	Yes Yes, developers can test individual back-end components with XCTest	Yes Turnip is used to test server-side behaviour and components
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes XCTest contains setup() and teardown() fixture methods for setting up and destroying test environments	No
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 Group fixtures are available in XCTest	No
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	No
Licence Licence type governing the use and redistribution of the software	Apache License 2.0	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 You can create protocol mocks and class mocks with libraries such as MockFive or Cuckoo	Yes By intergrating with RSpec turnip has access to the rspec-mocks gem
Grouping Allows organizing tests in groups	Yes Developers can define test suites from the XCTestSuite class	Yes Turnip Integrates directly into your RSpec test suite which allows declaring example groups and contexts.
