How do I group unit tests in Django at a higher granularity than the app?

In a Django project, unit test are usually organized by app, with Django providing a facility to run all of the tests, the tests for a single app, a single test case, or a single test method.

Yet, I find that test cases in a single application usually belong to separate logical groups or clusters, and it would be often useful to be able to only run a single group of tests. Imagine, for example:

I searched around. But while it is relatively straightforward to split your tests in multiple files (see for example these two questions), there doesn't seem to be a straightforward way to run the test groups separately.

So, am I missing something? What is the secret sauce to group tests?

For Django < 1.6
Personaly I do :

You have a init file :

myapp/tests/__init__.py :

from test1 import *
from test2 import *

def suite():
    import unittest
    #import doctest # If you want to use doctest

    TEST_CASES = ( 
     'sendim.tests.test1',
     'sendim.tests.test2',
    )   
    suite = unittest.TestSuite()

    #suite.addTest(doctest.DocTestSuite(object)) # object which have doctest
    for t in TEST_CASES :
        suite.addTest(unittest.TestLoader().loadTestsFromModule(__import__(t, globals(), locals(), fromlist=["*"])))
    return suite

And for example a testcase in a file named 'TestCase1' :

myapp/tests/test1.py :

from django.utils import unittest

class TestCase1(unittest.TestCase) :
    # Your testcase

If you launch ./manage.py test myapp, it will lauch every testcases.
Else if you launch `./manage.py test myapp.TestCase1, it will execute only this one.

It's worth looking at the nose test framework for python for one approach to this problem.

Specifically you can tag tests or set attributes on them. Then only run a subset of tests (across an app or your whole project) tagged with a given tag or tags.

https://nose.readthedocs.org/en/latest/plugins/attrib.html?highlight=tags

Note that nose extends unittest, so you're existing django unittest suite will likely already run with the nose runner.
