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

	Atoum http://atoum.org/	Shoulda https://github.com/thoughtbot/shoulda
Programming language	PHP	Ruby
Category	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	Meta gem containing Shoulda Context and Shoulda Matchers Shoulda contains two other gems: Should Context and Shoulda Matchers. Should Context allows better naming and grouping of your tests. Shoulda Matchers provides a set of "matchers", i.e. methods that allow you to write much more concise assertions.
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	N/A
Server-side Allows testing the bahovior of a server-side code	Yes Autom can perform unit tests on servers/back-end components	N/A
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	N/A
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	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.	N/A	N/A
Licence Licence type governing the use and redistribution of the software	Atoum License	MIT License
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	N/A
Grouping Allows organizing tests in groups	Yes By use of an extension for autom called blackfire which allows you to write blackfire test suites.	Yes
Other Other useful information about the testing framework		Shoulda Context is compatible with Minitest and Test::Unit. Shoulda Matchers is compatible with RSpec and Minitest.
