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

	Sleipnir https://github.com/railsware/Sleipnir	Atoum http://atoum.org/
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	Atoum is a unit testing framework specific to the PHP language Atoum is similar to SimpleTest and is designed to be implemented rapidly, simplify test development and allow for writing reliable, readable, and clear unit tests
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 Autom can perform unit tests on various front-end components and behaviours
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 Autom can perform unit tests on servers/back-end components
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 By using the 'given()' method to setup your environment
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 By using the 'given()' method to setup your environments
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	Atoum 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 Yes, developers can create mock objects with sleipnir using a third party library like Cuckoo.	Yes By use of autom mocks which are decoupled and easier to maintain
Grouping Allows organizing tests in groups	Yes You can declare example groups with Slepnir	Yes By use of an extension for autom called blackfire which allows you to write blackfire test suites.
