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

	Minitest https://github.com/seattlerb/minitest	Robot Framework https://robotframework.org/
Programming language	Ruby	Python
Category	Unit Testing	Acceptance Testing
General info	Complete suite of testing facilities Minitest is small, fast, and it aims to make tests clean and readable. It supports test-driven development (TDD), behavior-driven development (BDD), mocking, and benchmarking.	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.	Yes MiniTest is an xUnit style framework in that is has assertion functions in the style of xUnit/TDD	No
Client-side Allows testing code execution on the client, such as a web browser	No	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 various back-end components	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 Minitest supports test fixture functions	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 Minitest has 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.		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 Mocking is available through the Minitest::Mock class which is a simple and clean mock object framework	Yes Robot can access Python's mock library for mocking
Grouping Allows organizing tests in groups	Yes Allows grouping by nested Ruby classes. RSpec-like "context" method is available for spec syntax through the minitest-spec-context extension gem	Yes One can create a test suite with Robot
