Unit Testing

General info

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.

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.

Yes

Compatible

No

Client-side
Allows testing code execution on the client, such as a web browser

Yes

Sinon.js is a good library for unit testing your front-end code and has cross browser support

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

Sinon.js can run on node.js to test back-end components and server-side behaviour

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

N/A

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.

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.
