unittest

unit testing

Steve Purcell

Python standard lib

first unit test framework to be included in Python standard library; easy to use by people familiar with the xUnit frameworks; strong support for test organization and reuse via test suites

doctest

unit testing

Tim Peters

Python standard lib

copy and paste output from shell session; Agile Documentation: unit tests themselves can serve as documentation when combined with epydoc; also see Django's approach

pytest

unit testing

Holger Krekel

It used to be named py.test which was part of the pylib. Standalone now.

no API!;automatic collection of tests; simple asserts; strong support for test fixture/state management via setup/teardown hooks; strong debugging support via customized traceback

nose

unittest extensions

Jason Pellerin

unit test framework, used most notably by TurboGears and Pylons; provides an alternate test discovery and running process for unittest, one that is intended to mimic the behavior of py.test as much as is reasonably possible without resorting to too much magic. More friendly with unittest.TestCase-based tests than py.test. There are also many plugins available.

testify

unittest extensions

Yelp team

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

unittest extensions

Jonathan Lange

Twisted

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

unittest extensions

Robert Collins

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

unittest extensions

Robert Collins

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.

reahl.tofu

unit testing

Iwan Vosloo

Provides class based test Fixtures, in which several (usually interrelated) objects that need to be set up for tests are lumped together on a single object, called a Fixture. Fixtures are reusable and can depend on other Fixtures in turn. Fixtures can be used with any test framework, but easy integration is provided for pytest. A few other test utilities are included as well.

testtools

unittest extensions

Jonathan Lange

Useful extensions to unittest derived from custom extensions by projects such as Twisted and Bazaar.

Sancho

unit testing

MEMS and Nanotechnology Exchange

MEMS Exchange tools

Sancho 2.1 runs tests, and provides output for tests that fail; Sancho 2.1 does not count tests passed or failed; targets projects that do not maintain failing tests

zope.testing

unit testing

Zope3 community

Powerful test runner that includes support for post-mortem debugging of test failures. Also includes profiling and coverage reporting. This is a standalone package that has no dependencies on Zope and works just fine with projects that don't use Zope.

pry

unit testing

Aldo Cortesi

Elegant unit testing framework with built-in coverage analysis, profiling, micro-benchmarking and a powerful command-line interface.

pythoscope

unit testing

Michal Kwiatkowski

Tool that will automatically, or semi-automatically, generate unit tests for legacy systems written in Python.

testlib

unittest extensions

Logilab

logilab-common

Gives more power to standard unittest. More assert* methods; support for module level setup/teardown; skip test feature...

pytest

tests runner

Logilab

logilab-common

Tests finder / runner. Selectivly run tests; Stop on first failure; Run pdb on failed tests; Colorized reports; Run tests with coverage / profile enabled...

dutest

unittest extensions

Olemis Lang

PyOOP package (distributed separately too)

An object oriented interface to retrieve unittest test cases out of doctests. Hides initialization from doctests by allowing setUp and tearDown for each interactive example. Allows control over all the options provided by doctest. Specialized classes allow selective test discovery across a package hierarchy.

TestOOB

2009

unittest extensions

Ori Peleg

unittest enhancements; test filtering via regex/glob patterns; reporting in XML/HTML; colorized output; runs pdb on failing tests; run in parallel in threads/processes; verbose asserts; report failures immediately; and a little more;

pyUnitPerf

2009

performance-based unit testing

Grig Gheorghiu

port of JUnitPerf; transparently adds performance testing capabilities to existing unitttest-based test suites

Peckcheck

2008

specification-based unit testing

Darius Bacon

like the unittest module, except that test methods may take arguments; you declare each argument with a default value which names a test-data generator and the peckcheck module will peck at your test methods with a bunch of generated values

testosterone

2008

unit testing

Chad Whitacre

A manly test runner; command-line and curses(3) interfaces; the iPod of test runners. (More seriously, makes it easier to browse and inspect your test failures)

qunittest

2004

unit testing

Edgewall

Easy-to-use (PyQt) GUI framework and application for use with the Python unit testing framework. It can be used to conveniently execute unit tests and suites, and then display the results in a useful fashion.

Gustavo Rezende

Elegant test doubles framework in Python (mocks, stubs, spy, and dummies)

Python Mock

mock testing

Dave Kirby

Python Mock enables the easy creation of mock objects that can be used to emulate the behaviour of any class that the code under test depends on. You can set up expectations about the calls that are made to the mock object, and examine the history of calls made. This makes it easier to unit test classes in isolation. Download it here.

PyMock

mock testing

Jeff Younker

PyMock is based on the Java easymock package. It uses a recording and replay model rather than using a specification language. Easymock lives up to its name compared to other mocking packages. PyMock takes advantage of python's dynamic nature for futher improvements.
