pytest-django is a plugin for py.test that provides a set of useful tools for testing Django applications and projects.

Requirements

These packages are required to use pytest-django, when using pip they will be installed automatically.

  • Django 1.3+ (1.4 is supported)
  • py.test 2.3.4+

Quick Start

  1. pip install pytest-django
  2. Make sure DJANGO_SETTINGS_MODULE is defined and and run tests with the py.test command.
  3. (Optionally) If you put your tests under a tests directory (the standard Django application layout), and your files are not named test_FOO.py, see the FAQ

Documentation

Documentation is available on Read the Docs.

Why would I use this instead of Django's manage.py test command?

Running the test suite with py.test offers some features that are not present in Djangos standard test mechanism:

  • Smarter test discovery (no need for from .foo import * in your test modules).
  • Less boilerplate: no need to import unittest, create a subclass with methods. Just write tests as regular functions.
  • Injection of test depencies with funcargs
  • No need to run all tests, it is easy to specify which tests to run.
  • Database re-use: no need to re-create the test database for every test run.
  • No hacks required to only run your apps, and not the 3rd party/contrib apps that is listed in your INSTALLED_APPS.
  • There are a lot of other nice plugins available for py.test.
  • No pain of switching: Existing unittest-style tests will still work without any modifications.

See the py.test documentation for more information on py.test.
