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

	PHPUnit https://phpunit.de/	TwistedTrial https://twistedmatrix.com/trac/wiki/TwistedTrial
Programming language	PHP	Python
Category	Unit Testing	Unit Testing, unittest Extensions
General info	PHPUnit is a unit testing framework for the PHP programming language PHPUnit is a programmer-oriented testing framework and is an instance of the xUnit architecture for unit testing frameworks.	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.	Yes It's an instance of the xUnit architecture for unit testing frameworks	No
Client-side Allows testing code execution on the client, such as a web browser	Yes It can perform Unit tests and can test various front-end components and behaviours	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 By performing unit tests on singular back-end 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 By use of a setup code. The setup code consists of two Important template functions, the 'setUp()' function (called to create the objects to be tested) and 'tearDown()' function (called to cleanup the objects which you tested)	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 does support group 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.	N/A	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 One of its main features is that PHPUnit comes with out of the box support for Mock objects	Yes Trial can access the mock library inbuilt in python for mocking purposes
Grouping Allows organizing tests in groups	Yes It allows grouping of tests and by using the @group annotation one can tag a test to belong to one or more groups	Yes Trial allows tests to be grouped into test packages
