Quick vs Cypress.io comparison of testing frameworks
What are the differences between Quick and Cypress.io?

	Quick https://github.com/quick/quick	Cypress.io https://www.cypress.io/
Programming language	Swift	JavaScript
Category	Acceptance Testing, Unit Testing	End-to-End Testing, Intergration Testing, Unit Testing
General info	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.	Cypress users are typically developers or QA engineers building web applications using modern JavaScript frameworks. This is the top tier UI automation framework which outsmarts Selenium based frameworks in most of the aspects! Cypress enables you to write all types of tests: 1. End-to-end tests; 2. Integration tests; 3. Unit tests; 4. Cypress can test anything that runs in a browser; Apart from that Cypress provides the Dashboard facility for CI/CD
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes Yes, it is an xUnit style test framework	No
Client-side Allows testing code execution on the client, such as a web browser	Yes Developers can test front-end behaviour and components by defining front-end feature specifications	Yes This is the primary goal of Cypress, it tests anything that runs in a browser and works to build great user experience that is it tests the applications flow from beginning to end from a user's perspective. It is built to handle modern JavaScript frameworks especially well and also works equally well on older server rendered pages or applications
Server-side Allows testing the bahovior of a server-side code	Yes Developers can test back-end behaviour and components by defining back-end feature specifications	Yes Although Cypress is not a general automation framework, nor is it a unit testing framework for your back-end services, It can test back-end behaviours for example using cy.task() command which provides a way for running Node code, so you can take actions necessary for your tests outside of the scope of Cypress
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes Quick contains fixture methods setup() and teardown() for setting up and destroying test environments	Yes Cypress has inbuilt fixtures capabilities or example using the command 'cy.fixture(filePath)' loads a fixed set of data located in a file
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 Yes, example groups (logical groupings of examples/tests) can share setup and teardown code	Yes Cypress can create group fixtures using the 'cy.fixture' command
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	N/A
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 Yes, developers can create mock objects with Quick using the Cuckoo library	Yes Cypress comes built in with the ability to stub and spy with cy.stub(), cy.spy(), It also automatically bundles 'sinon', 'lolex' and 'sinon-chai' which all work to give Cypress mocking capabilities
Grouping Allows organizing tests in groups	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.	Yes Cypress allows you to configure tests into groups however there is no way currently to run the groups
