Atoum vs PHPSpec comparison of testing frameworks
What are the differences between Atoum and PHPSpec?

	Atoum http://atoum.org/	PHPSpec https://www.phpspec.net/en/stable/
Programming language	PHP	PHP
Category	Unit Testing	Unit Testing
General info	Atoum is a unit testing framework specific to the PHP language Atoum is similar to SimpleTest and is designed to be implemented rapidly, simplify test development and allow for writing reliable, readable, and clear unit tests	PhpSpec is a testing tool based on the concept of emergent design using specification PhpSpec is a tool to use at the spec level or SpecBDD, a type of BDD; It's process generates code for you and guides you through the SpecBDD process through the command line
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	No
Client-side Allows testing code execution on the client, such as a web browser	Yes Autom can perform unit tests on various front-end components and behaviours	Yes By testing your PHP classes that run your front-end
Server-side Allows testing the bahovior of a server-side code	Yes Autom can perform unit tests on servers/back-end components	Yes You can use PHPSpec to test your PHP classes that run your back-end
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 the 'given()' method to setup your environment	Yes You can define 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.	Yes By using the 'given()' method to setup your environments	Yes You can define group fixtures
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	Yes There are methods that act as generators
Licence Licence type governing the use and redistribution of the software	Atoum License	Free
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)	Yes By use of autom mocks which are decoupled and easier to maintain	Yes It has built in support for Mocks
Grouping Allows organizing tests in groups	Yes By use of an extension for autom called blackfire which allows you to write blackfire test suites.	In PHPspec, you can group specification files by a certain namespace in a suite
