TMF vs Jest comparison of testing frameworks
What are the differences between TMF and Jest?

	TMF https://github.com/bowsersenior/tmf	Jest https://jestjs.io
Programming language	Ruby	JavaScript
Category	Unit Testing	Unit Testing
General info	TMF is a minimal testing tool for ruby TMF is a very small testing tool, it's not even a gem, you just copy the code and you're done. it uses just two methods to test: assert and stub	A Unit Testing framework focused on simplicity This is a Unit test framwork especially designed for the React.JS, Babel, TypeScript, Node, React, Angular and Vue projects. It usually worked with Enzyme(Integration testing)
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 You can easily test methods, properties, UI element actions and other front-end functionalities
Server-side Allows testing the bahovior of a server-side code	Yes You can test back-end components with TMF	Yes Back-end server behaviour also can be tested with Jest much in the same way as the front-end tests.
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	No	Yes Fixtures are supported, Jest has many helper functions such as: BeforeEach and afterEach If you have some work you need to do repeatedly for many tests, beforeAll and afterAll if you only need to do setup once, at the beginning of a file.
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.	No	Yes Jest supports 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.	No	N/A

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)	No	Jest uses a custom resolver for imports in your tests making it simple to mock any object outside of your test’s scope. You can use mocked imports with the rich Mock Functions API to spy on function calls with readable test syntax.
Grouping Allows organizing tests in groups	No	Yes You can declare as many test suites as you want. Grouping of tests together is done using a describe block
