Unit Testing

General info

JS Unit test framework, BDD based for Node.JS applications used with Angular.JS web applications and also paired with 'Karma' task runner

It's a BDD (Behavior Driven Development) test framework for JavaScript especially designed for manual QAs to understand the automation tests. It does not depend on the any JavaScript framework or browser. So it's very well suited for Node.js projects and websites

A Unit testing test runner for JavaScript

Test'em is framework agnostic and has support for Jasmine, Qunit, Mocha and others through custom test framework adapters. It canalso run tests on all major browsers as well as Node and Phantomjs
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

It has an xUnit reporter
Client-side
Allows testing code execution on the client, such as a web browser

Yes

Jasmine works well in and with browsers to test client-side components and functionality

Server-side
Allows testing the bahovior of a server-side code

Yes

Jasmine works with NodeJs to test its back-end components and behaviour

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

Yes

By using 'jasmine-fixture' which can help write specs that interact with the DOM making it easier to injectHTML fixtures

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.

N/A

Licence

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)

By using a a plugin called jasmine-ajax that allows ajax calls to be mocked out in tests

Grouping
Allows organizing tests in groups

Yes

Using the describe function which is for grouping related tests, typically each test file has one at the top level.
