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

	Arquillian http://arquillian.org/	Sleipnir https://github.com/railsware/Sleipnir
Programming language	Java	Swift
Category	Intergration Testing, Functional Testing	Unit Testing, Acceptance Testing
General info	Arquillian is an Open source framework for writing Integration and functional tests Arquilian comes bundled with many extra tools such as Arquillian graphene, Drone and Selenium to write tests to the visual layer as well	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 is a xUnit framework	N/A
Client-side Allows testing code execution on the client, such as a web browser	Yes You can perform unit tests on 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 You can unit tests on back-end behaviours and functionalities by testing specific back-end classes and functions	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 use of extensions, for example you can use the Persistence extension to set database fixtures	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 define group fixtures	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	N/A
Licence Licence type governing the use and redistribution of the software	Apache License 2.0	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)	Yes Arquillian supports mock object functionality you can use third party libraries	Yes Yes, developers can create mock objects with sleipnir using a third party library like Cuckoo.
Grouping Allows organizing tests in groups	Yes Arquilian supports grouping of tests	Yes You can declare example groups with Slepnir
