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

	Sleipnir https://github.com/railsware/Sleipnir	PHPSpec https://www.phpspec.net/en/stable/
Programming language	Swift	PHP
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	PhpSpec is a testing tool based on the concept of emergent design using specification PhpSpec is a tool to use at the spec level or SpecBDD, a type of BDD; It's process generates code for you and guides you through the SpecBDD process through the command line
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	N/A	No
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 By testing your PHP classes that run your front-end
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 You can use PHPSpec to test your PHP classes that run your 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 Fixtures are available by using beforeEach{ } and afterEach{ } to setup the test parameters	Yes You can define fixtures
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	Yes You can define 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	Yes There are methods that act as generators
Licence Licence type governing the use and redistribution of the software	MIT License	Free
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.	Yes It has built in support for Mocks
Grouping Allows organizing tests in groups	Yes You can declare example groups with Slepnir	In PHPspec, you can group specification files by a certain namespace in a suite
