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

	QUnit https://qunitjs.com/	Sleipnir https://github.com/railsware/Sleipnir
Programming language	JavaScript	Swift
Category	Unit Testing	Unit Testing, Acceptance Testing
General info	QUnit is a JS Unit testing framework. QUnit is especially useful for regression testing of jQuery, jQuery UI and jQuery Mobile projects	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 Yes, it is a xUnit style framework	N/A
Client-side Allows testing code execution on the client, such as a web browser	Yes QUnit is commonly used by jQuery, jQuery UI and jQuery Mobile It can test front-end components and 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 Qunit can test any JavaScript code(including itself), this includes server-side components and functionality. Supports NodeJs	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	Yes By using the qunit-fixture element which is a container for some HTML that your tests can assert against.	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.	Yes You can group fixtures together with QUnit	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.		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)	You can use third party libraries like jQuery's Mockjax plugin	Yes Yes, developers can create mock objects with sleipnir using a third party library like Cuckoo.
Grouping Allows organizing tests in groups	Yes You can use the QUnit.module() function to group tests together	Yes You can declare example groups with Slepnir
