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

	JBehave https://jbehave.org/	TwistedTrial https://twistedmatrix.com/trac/wiki/TwistedTrial
Programming language	Java	Python
Category	Acceptance Testing	Unit Testing, unittest Extensions
General info	JBehave is a Behaviour-Driven Development testing framework for java JBehave is a Behaviour Driven Development framework. It intends to provide an intuitive and accessible way for automated acceptance testing	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 You can test front-end behaviour (scenarios) with JBehave	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	JBehave tests scenarios and behaviours of components, it can test back-end behaviour	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 You have a few options for using fixtures in JBehave: you can run your steps before/after each scenario by using LifeCycle: you can use @BeforeStory and @AfterStory annotations or you can define a dummy scenario with your setup/teardown steps	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 You can define group fixtures with JBehave	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.	No	Through use of third party libraries like test-generator.
Licence Licence type governing the use and redistribution of the software	BSD-style 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)	The best way to mock is to use third party libraries like Mockito, Jmock or Jmockit	Yes Trial can access the mock library inbuilt in python for mocking purposes
Grouping Allows organizing tests in groups	N/A	Yes Trial allows tests to be grouped into test packages
