xUnit frameworks

  • frameworks
    • unittest - is a library to make unit testing distributed with python out of the box.
    • unittest2 - is a backport of the new features added to the unittest testing framework in Python 2.7 and onwards.
    • pytest - is a mature full-featured Python testing tool that helps you write better programs.
      • plugincompat - Test execution and compatibility checks for pytest plugins
    • nosetests - is a nicer testing for python.
    • slash - is a testing framework written in Python.
    • lemoncheesecake - is a Python framework intended to functional testing, it provides fixtures, matchers, test organization through test suites hierarchy and metadata (test/suite name, description, tags, properties, links), rich reporting features and various report formats (JSON, XML, HTML, Junit)
  • extensions
    • proboscis - is a Python test framework that extends Python’s built-in unittest module and Nose with features from TestNG.
    • grail - is a library which allows test script creation based on steps.
    • testify - unit test framework, provides Enhanced test fixture setup, Split test suites into buckets for easy parallelization, PEP8 naming conventions & Fancy color test runner with lots of logging / reporting option.
    • trial - Extension of unittest to support writing asynchronous unit tests using Deferreds and new result types ('skip' and 'todo'). Includes a command-line program that does test discovery and integrates with doctest and coverage.
    • subunit - Transparently adds support for running unittest test cases/suites in a separate process : prevents system wide changes by a test destabilising the test runner. It also allows reporting from tests in another process into the unittest framework, giving a single integrated test environment.
    • testresources - Provides a mechanism for managing 'resources' - expensive bits of infrastructure - that are needed by multiple tests. Resources are constructed and free on demand, but with an optional TestSuite?, the test run order is optimised to reduce the number of resource constructions and releases needed. Compatible with unittest.
