PHPUnit is a programmer-oriented testing framework for PHP. It is an instance of the xUnit architecture for unit testing frameworks. 

Mockery is a simple yet flexible PHP mock object framework for use in unit testing with PHPUnit, PHPSpec or any other testing framework. Its core goal is to offer a test double framework with a succinct API capable of clearly defining all possible object operations and interactions using a human readable Domain Specific Language (DSL).

Its core goal is to offer a test double framework with a succinct API capable of clearly defining all possible object operations and interactions using a human readable Domain Specific Language (DSL). Designed as a drop in alternative to PHPUnit's phpunit-mock-objects library, Mockery is easy to integrate with PHPUnit and can operate alongside phpunit-mock-objects without the World ending. Mockery is released under a New BSD License.

The root and a fork of atoum, the modern, simple and intuitive PHP 5.3+ unit testing framework.

Atoum was made because its original author thinks that unit testing must be simple, fast and fun (as possible) to write and execute. atoum is really easy to install: clone it from github, download its PHAR or simply use composer, atoum provides a high level of security during test execution by isolating each test method in its own PHP process. Of course, this feature is available out of the box, no need to install any additional extension, atoum runs tests in a parallelized environment making the suite run as fast as possible by taking advantage of today's multi-core CPUs, atoum provides a full-featured set of natural and expressive assertions making tests as readable as possible. Here is an example: atoum supports a BDD-like syntax with a lot of structural keywords: atoum provides a dead simple, yet very powerful, mock engine: atoum provides a clear API to assert on exceptions: atoum also lets you mock native PHP functions. Again, this is available out of the box: atoum is able to produce several reports like TAP, clover, xUnit to be easily integrated with Jenkins or any other continuous integration tool, atoum supports data providers, atoum tests support autorun: just include the atoum runner and launch your test using php path/to/test/file.php, atoum's configuration file is exclusively written in PHP (no XML, YAML or any other format) giving you the best flexibility: atoum provides an automatic test template generator, atoum provides a loop mode to easily retrigger failed tests, atoum is full of other interesting features that you will discover over the time.
