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

	Robot Framework https://robotframework.org/	Cuppa http://cuppa.forgerock.org/
Programming language	Python	Java
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.	Cuppa is a testing framework for Java 8+ Cuppa is a testing framework for Java 8+ that is descriptive that is; it uses strings,not identifiers , to clearly describe the behaviour you are testing it also allows you to Group tests together by creating a structure in your test files to reduce repetition and improve readability and also you Define tests at runtime
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	No
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 your front-end code as individual components of code
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 server-side components and functionality with Cuppa.
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	Yes Fixtures are available via the Setup and Teardown functions
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 You groups of tests can share these fixture methods
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	N/A
Licence Licence type governing the use and redistribution of the software	Apache License 2.0	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 Robot can access Python's mock library for mocking	N/A
Grouping Allows organizing tests in groups	Yes One can create a test suite with Robot	Yes This is a feature of cuppa, it allows you to group your tests together
