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

	TwistedTrial https://twistedmatrix.com/trac/wiki/TwistedTrial	JGiven http://jgiven.org/
Programming language	Python	Java
Category	Unit Testing, unittest Extensions	Acceptance Testing
General info	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'	JGiven is a BDD tool for Java in plain java. With JGiven Developers write scenarios in plain Java using a fluent, domain-specific API, JGiven generates reports that are readable by domain experts.
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 Front-end components can be tested for example adding a web front-end using simple twisted.web.resource.Resource objects	Yes You can test UI functionality or behaviour by writing scenarios that cover front-end behaviour
Server-side Allows testing the bahovior of a server-side code	Yes Server-side behaviour can be tested with Trial, it has various functions for this in the twisted.web.Resource package	Yes You can write 'scenarios' to test server-side behaviours
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	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 Methods like 'setUp()' allow for creation of group fixtures	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.	Through use of third party libraries like test-generator.	N/A
Licence Licence type governing the use and redistribution of the software	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 Trial can access the mock library inbuilt in python for mocking purposes	Yes You can use third party libraries such as JMock and JMockit to mock objects and functions
Grouping Allows organizing tests in groups	Yes Trial allows tests to be grouped into test packages
