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

	Tape https://github.com/substack/tape	Sleipnir https://github.com/railsware/Sleipnir
Programming language	JavaScript	Swift
Category	Unit Testing, Intergration Testing	Unit Testing, Acceptance Testing
General info	tap-producing test harness for node and browsers. Tape API is a small superset of the node core assert module	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.	Yes It does support xUnit output	N/A
Client-side Allows testing code execution on the client, such as a web browser	Yes You can write tests for any part of your front-end code to test any component or 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 With tape you can test any back-end component, behaviour and functionality after all it supports TAP (Test Anything Protocol)	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 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	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)	No Tape is a minimalistic framework that provides only essential features to make your assertions about your code	Yes Yes, developers can create mock objects with sleipnir using a third party library like Cuckoo.
Grouping Allows organizing tests in groups	No Tape contains only the essential features for making assertions on your code	Yes You can declare example groups with Slepnir
