General info	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	Standalone test stubs and mocks for JavaScript. Works with any unit testing framework. Sinon.js is a great library when you want to unit test your code with supports spies, stubs, and mocks. The library has cross browser support and also can run on the server using Node.js.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes Compatible
Client-side Allows testing code execution on the client, such as a web browser	Yes You can test your front-end code as individual components of code	Yes Sinon.js is a good library for unit testing your front-end code and has cross browser support
Server-side Allows testing the bahovior of a server-side code	Yes You can test server-side components and functionality with Cuppa.	Yes Sinon.js can run on node.js to test back-end components and server-side behaviour
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 via the Setup and Teardown functions	N/A
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 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.	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)	N/A	Yes SinonJS is basically a library that we can use to create object mocks for unit testing
Grouping Allows organizing tests in groups	Yes This is a feature of cuppa, it allows you to group your tests together
