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

	XCTest https://developer.apple.com/documentation/xctest	Tape https://github.com/substack/tape
Programming language	Swift	JavaScript
Category	Unit Testing, Performance Testing	Unit Testing, Intergration 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.	tap-producing test harness for node and browsers. Tape API is a small superset of the node core assert module
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	Yes It does support xUnit output
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 You can write tests for any part of your front-end code to test any component or functionality
Server-side Allows testing the bahovior of a server-side code	Yes Yes, developers can test individual back-end components with XCTest	Yes With tape you can test any back-end component, behaviour and functionality after all it supports TAP (Test Anything Protocol)
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 Tape contains only the essential features for making assertions on your code but there is a package called redtape that extends tape to give you beforeEach and afterEach functionality
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	No Tape is a minimalistic framework that provides only essential features to make your assertions about your code
Grouping Allows organizing tests in groups	Yes Developers can define test suites from the XCTestSuite class	No Tape contains only the essential features for making assertions on your code
