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

	SimpleTest https://github.com/simpletest/simpletest	TwistedTrial https://twistedmatrix.com/trac/wiki/TwistedTrial
Programming language	PHP	Python
Category	Unit Testing, Web Testing	Unit Testing, unittest Extensions
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	Trial is a unit testing framework for Python built by Twisted Matrix labs Trial is composed of two parts: First is a command-line test runner, which can be run on plain Python unit tests and can do automated unit-test discovery across files, modules, or even arbitrarily nested packages. Second is a test library, derived from Python's 'unittest.TestCase'
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 With SimpleTest common but fiddly PHP tasks, such as logging into a site, can be tested easily	Yes Front-end components can be tested for example adding a web front-end using simple twisted.web.resource.Resource objects
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 Server-side behaviour can be tested with Trial, it has various functions for this in the twisted.web.Resource package
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 Trial supports various fixture methods such as 'setUp()' and 'tearDown' functions fixture for normal semantics of setup, and teardown
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 Methods like 'setUp()' allow for creation of 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	Through use of third party libraries like test-generator.

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 Trial can access the mock library inbuilt in python for mocking purposes
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 Trial allows tests to be grouped into test packages
