Sleipnir vs Wallaby.js comparison of testing frameworks
What are the differences between Sleipnir and Wallaby.js?

	Sleipnir https://github.com/railsware/Sleipnir	Wallaby.js https://wallabyjs.com/
Programming language	Swift	JavaScript
Category	Unit Testing, Acceptance Testing	Unit Testing
General info	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	Wallaby.js is an integrated continuous testing tool for JavaScript. Wallaby.js runs your tests immediately as you change your code (you don’t even have to save the file) and reports code coverage and other results directly to your code editor. Its also uses various techniques such as dependency analysis to only execute tests affected by your code changes and parallel test execution to ensure your tests run as fast as possible.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	N/A	N/A
Client-side Allows testing code execution on the client, such as a web browser	Yes You can test front-end behaviour by defining specifications for classes, objects and functions	Yes Wallaby.js can test front-end components and functionality
Server-side Allows testing the bahovior of a server-side code	Yes You can test back-end behaviour by defining specifications for classes, objects and functions in the back-end	Yes Wallaby.js can test server behaviour and functionality
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes Fixtures are available by using beforeEach{ } and afterEach{ } to setup the test parameters	N/A
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 through the beforeAll{} and afterAll{} blocks to setup group fixtures	N/A
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	MIT License	N/A
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 sleipnir using a third party library like Cuckoo.	By use of a third party library Jest works well with wallaby
Grouping Allows organizing tests in groups	Yes You can declare example groups with Slepnir
