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

	Sleipnir https://github.com/railsware/Sleipnir	Robot Framework https://robotframework.org/
Programming language	Swift	Python
Category	Unit Testing, Acceptance Testing	Acceptance 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	Robot is a Python framework used for acceptance/functional testing Robot is an automated test framework which has a simple plain text syntax and can be extended easily with Python or Java libraries. It can run on the .net-based IronPython and on Jython which is Java based.
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 Robot has a rich library and can also be easily integrated with Selenium for browser automation to test front-end components
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 Robot can be used for back-end tests as well
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	There is no inbuilt way to work with fixtures in Robot however it can integrate with unittest and use fixtures that way
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	By integrating with unittest
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 Robot has a library called the Robot Framework Faker library. It contains 147 keywords used for generating random test data
Licence Licence type governing the use and redistribution of the software	MIT License	Apache License 2.0
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 Robot can access Python's mock library for mocking
Grouping Allows organizing tests in groups	Yes You can declare example groups with Slepnir	Yes One can create a test suite with Robot
