General info

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

Unitils is an open source library whose goal is to make unit and integration testing easy and maintainable.

Unitils is divided into modules, each of them providing support for a certain aspect of your unit and integration tests. For example if you need mocking for your tests, just include unitils-mock as a dependency, If you would also want to load DbUnit data sets, just include unitils-dbunit
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

It has an xUnit reporter

No

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

Yes

You can perform unit tests on various components and functionality that make up the front-end
Server-side
Allows testing the bahovior of a server-side code

Yes

Unitils provides support for testing the back-end through modules such as DbUnit which specifically tests your database, i.e connections setup and so on
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

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.

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.

Licence
Licence type governing the use and redistribution of the software

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)

Grouping
Allows organizing tests in groups
