Django Test Tools

The Django Test Tools is a set of utilities and tools to make django tests faster and easier to maintain. Currently application provide test runner with persistent database. The test database would be automatically sync'ed and migrated along with main database.


  1. Add the test_tools directory to your Python path.

  2. Add test_tools to your INSTALLED_APPS setting so Django can find the signals.

  3. Set test runner. You can use jenkins test runner as well but django_jenkins should be in your INSTALLED_APPS:

    TEST_RUNNER = 'test_tools.test_runner.DiscoveryDjangoTestSuiteRunner'
    JENKINS_TEST_RUNNER = 'test_tools.test_runner.JenkinsDiscoveryDjangoTestSuiteRunner'
  4. Create test database so application can sync it and probably migrate. Name for test database can be set in DATABASES as TEST_NAME. If TEST_NAME is not provided the test_ prefix would be added to regular database NAME.


  1. test_tools.utils.model_factory Factory for creating objects in place since fixtures may be slow and hard to maintain sometimes. The basic usage:

    user = model_factory(User, username='john')
    # or
    user1, user2 = model_factory(User, username='john', num=2)

    Factory will return NOT saved user object by default. To make an actual insert save=True should be passed as following:

    user = model_factory(User, username='john', save=True)

    There is a possibility to create a bunch of objects:

    users = model_factory(User, username=['john', 'tom'], last_name=['Smith', 'Green'], save=True)
    # note, that
    model_factory(User, username=['john', 'tom'], num=2)
    # will return [User('john'), User('john'), User('tom'), User('tom')]

    The length of every list should be equal. Besides that model_factory return DebugList object which has methods to build a diffs for list of objects. Here is an example:

    excpected_users = model_factory(User, username=['john', 'tom'], last_name=['Smith', 'Green'], save=True)
    self.assertEqual(excpected_users, actual_users, excpected_users.get_diff(actual_users))
    # You would get something like::
    AssertionError: Expected length: 3 but got 4 objects
    Missed objects:
    Discount(already_used=2, active=False, allowed_uses=1, start_date=2012-05-03 12:07:22.080689, end_date=2012-05-03 12:07:22.080689)
    Extra objects:
    Discount(already_used=None, active=True, allowed_uses=None, start_date=2012-05-10, end_date=2012-05-03)
    Discount(already_used=None, active=True, allowed_uses=None, start_date=2012-05-03, end_date=2012-04-26)
  2. test_tools.utils.get_fake_email: Simply return one or more fake emails:

    # this will return ''
    # this will return ['', '']
  3. test_tools.utils.site_required: This decorator simply creates a Site object before decorated test or test case runs.

  4. test_tools.utils.no_database: Decorator which replace django's cursor with mock object and raise an error if test trying to access database. Wrap your test with @no_database if you are sure that test shouldn't access database.

  5. test_tools.utils.profile: Decorator which writes a profiling log with hotshot module. You can specify the folder by PROFILE_LOG_BASE in It is set to /tmp by default:

    def test_something(self):

    Then you can read the log by something like:

    stats = hotshot.stats.load('/tmp/')
