Unit Testing

General info

This library was designed to work for both Node.js and browser interpreters and it encourages the TDD (Test Driven Development)

Test doubles can be used with conjuction of other test frameworks such as Jasmine, Jest, Chai, QUnit, Mocha, Tape etc.

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.

Yes

It is compatible with xUnit and supportsxUnit XML output

Yes

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

No

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

Testdouble is primarily used to test server-side functions, behaviours and components

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

N/A

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.

N/A

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.

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

Testdouble includes inbuilt support for mocking

Yes

SinonJS is basically a library that we can use to create object mocks for unit testing
Grouping
Allows organizing tests in groups
