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.

Randoop.NET is an API fuzzing unit test generator for .NET libraries.

Randoop.NET creates test cases by a sequence of API method calls and it improves on random and static test generation by incorporating feedback during test generation.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

Yes

Compatible

Yes

Randoop.net is an xUnit style testing framework
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 front-end components by testing individual front-end classes and modules
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 back-end components by testing individual back-end classes and modules
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

SinonJS is basically a library that we can use to create object mocks for unit testing

N/A

Grouping
Allows organizing tests in groups

Yes

You can generate test suites with Randoop
