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

EvoSuite is a tool that automatically generates unit tests for Java software

EvoSuite is a tool that automatically generates test cases with assertions for classes written in Java code by applying a hybrid approach that generates and optimizes whole test suites towards satisfying a coverage criterion
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 test front-end code by testing the classes that provide front-end functionality
Server-side
Allows testing the bahovior of a server-side code

Yes

You can test server-side functionality and components
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

You can write your own fixtures but no inbuilt fixtures are provided
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.
