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

	Robot Framework https://robotframework.org/	Kiwi https://github.com/kiwi-bdd/Kiwi
Programming language	Python	Swift
Category	Acceptance Testing	Unit Testing
General info	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.	Kiwi is a Behavior Driven Development library for iOS development The goal behind Kiwi is to provide a BDD library that is simple to setup and use, and create tests that are more readable than what is possible with the bundled test framework.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes Kiwi is an xUnit style framework
Client-side Allows testing code execution on the client, such as a web browser	Yes Robot has a rich library and can also be easily integrated with Selenium for browser automation to test front-end components	Yes You can test front-end components with kiwi
Server-side Allows testing the bahovior of a server-side code	Yes Robot can be used for back-end tests as well	Yes You can test back-end components with kiwi
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	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.	By integrating with unittest	Yes kiwi has a beforeEach(aBlock) which is run before every 'it' block in all enclosed contexts. Code that sets up the particular context should go here and afterEach(aBlock) which is run after every it block in all enclosed contexts
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 Robot has a library called the Robot Framework Faker library. It contains 147 keywords used for generating random test data	Yes through the beforeAll(aBlock) and afterAll(aBlock) functions.
Licence Licence type governing the use and redistribution of the software	Apache License 2.0	Proprietary, Open source
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 Robot can access Python's mock library for mocking	Yes Kiwi has inbuilt support for stubs and mocks,including null mocks, class mocks, protocol mocks
Grouping Allows organizing tests in groups	Yes One can create a test suite with Robot	Yes Kiwi uses the block syntax in iOS to define groups of assertions and share setup state between collections of tests
