RSpec vs Quick comparison of testing frameworks
What are the differences between RSpec and Quick?

	RSpec https://rspec.info	Quick https://github.com/quick/quick
Programming language	Ruby	Swift
Category	Unit Testing, Intergration Testing	Acceptance Testing, Unit Testing
General info	Domain Specific Language (DSL) testing solution for Ruby code It focuses on empowering Test Driven Development (TDD). RSpec contains multiple smaller libraries, which may be independently used with other testing frameworks.	Quick is a Swift (and Objective-C) testing framework. Quick is a behavior-driven development framework for Swift and Objective-C that is inspired by RSpec, Specta, and Ginkgo. Quick comes bundled with Nimble a matcher framework for your tests.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes Yes, but it differs from more traiditional xUnit solutions. Its tests are written in a "Tests as Specification" manner. This means that the terminology used in RSpec is adjusted to a language more fitting for specification.	Yes Yes, it is an xUnit style test framework
Client-side Allows testing code execution on the client, such as a web browser	Yes RSpec is used to primarily test the behaviour of applications or individual components so it can test front-end behaviour as well - you can use capybara gem with RSpec for that.	Yes Developers can test front-end behaviour and components by defining front-end feature specifications
Server-side Allows testing the bahovior of a server-side code	Yes You can test server-side behaviour with Rspec	Yes Developers can test back-end behaviour and components by defining back-end feature specifications
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes RSpec does contain fixture methods	Yes Quick contains fixture methods setup() and teardown() for setting up and destroying test environments
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 fixture methods are supported	Yes Yes, example groups (logical groupings of examples/tests) can share setup and teardown code
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 RSpec contains generators for example intergration_'test_name' which will save a spec inside the spec/requests folder	N/A
Licence Licence type governing the use and redistribution of the software	MIT License	Apache License 2.0
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 Available through rspec-mocks gem.	Yes Yes, developers can create mock objects with Quick using the Cuckoo library
Grouping Allows organizing tests in groups	Yes Allows declaring example groups and contexts.	Yes In Quick test suites are named Specs, and every test suite you create starts off with a class inheriting from QuickSpec includes a main method, spec() which contains all the test cases.
