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

Category	Unit Testing	Unit Testing, Acceptance Testing
General info	unittest is a unit testing framework for Python The unittest test framework is Python’s xUnit style framework. It is a standard module that is bundled with Python and supports the automation and aggregation of tests and common setup and shutdown code for them.	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 unittest is a xUnit style frameworkfor Python, it was previously called PyUnit.	N/A
Client-side Allows testing code execution on the client, such as a web browser	Yes Front-end functionality and behaviour can be tested by unittest.	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 Since the webserver funtionalities have their own features and each feature has its own functions, we can write tests with unittest to test each function	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 the 'setUp()' function which is called to prepare the test fixture	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 unittest allows you to group your initialization code into a setUp function and clean up code in a tearDown function	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.	Yes unittest contains generator methods in the module 'unittest.TestCase'	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)	Yes Mocks are available from the library unittest.mock which allows you to replace parts of your system under test with mock objects	Yes Yes, developers can create mock objects with sleipnir using a third party library like Cuckoo.
Grouping Allows organizing tests in groups	Yes One can build suites either manually or use test discovery to build the suite automatically by scanning a directory	Yes You can declare example groups with Slepnir
