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.

Spinach is a BDD framework on top of Gherkin

Spinach is a high-level BDD framework that leverages the Gherkin language to help define executable specifications of your application or library's acceptance criteria.
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

N/A

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 any server-side behaviour with Spinach
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

N/A

No

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

Spinach has inbuilt generator methods
