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
