SimpleTest vs Arquillian comparison of testing frameworks
What are the differences between SimpleTest and Arquillian?

	SimpleTest https://github.com/simpletest/simpletest	Arquillian http://arquillian.org/
Programming language	PHP	Java
Category	Unit Testing, Web Testing	Intergration Testing, Functional Testing
General info	SimpleTest is a unit test and web test framework for PHP It has JWebUnit style functionality and support for SSL, forms, frames, proxies and basic authentication	Arquillian is an Open source framework for writing Integration and functional tests Arquilian comes bundled with many extra tools such as Arquillian graphene, Drone and Selenium to write tests to the visual layer as well
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes It is a xUnit framework
Client-side Allows testing code execution on the client, such as a web browser	Yes With SimpleTest common but fiddly PHP tasks, such as logging into a site, can be tested easily	Yes You can perform unit tests on front-end components and functionality
Server-side Allows testing the bahovior of a server-side code	Yes Server-side behaviour can be tested by writing simple unit tests to test functionality and behaviour of single components.	Yes You can unit tests on back-end behaviours and functionalities by testing specific back-end classes and functions
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes It can import fixtures using a mixin like 'given()' method	Yes By use of extensions, for example you can use the Persistence extension to set database 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 It allows grouping of fixtures	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.	Yes Simpletest has support for generators	N/A

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 It allows for one to build Mock objects.To create a mock version of a class we need to include the mock object library and run the generator. This will create a clone class which we use to create new instances(objects) in our test cases.	Yes Arquillian supports mock object functionality you can use third party libraries
Grouping Allows organizing tests in groups	Yes There are several ways of grouping tests; one is to simply place multiple test cases into a single file, another is to mark any base test cases that should not be run as abstract, Simpletest gives you a couple of options	Yes Arquilian supports grouping of tests
