Django has a weird design decision wherein TransactionTestCase doesn't
clean up after itself. Instead, it resets the DB to a clean state only
at the *beginning* of each test:
https://docs.djangoproject.com/en/dev/topics/testing/?from=olddocs#
django. test.TransactionTestCase. Thus, Django reorders tests so
TransactionTestCases all come last. Here we do the same.
"I think it's historical. We used to have doctests also, adding cleanup
after each unit test wouldn't necessarily clean up after doctests, so
you'd have to clean on entry to a test anyway." was once uttered on
#django-dev.

def filthiness(test):
"""Return a comparand based on whether a test is guessed to clean
up after itself.
Django's TransactionTestCase doesn't clean up the DB on teardown,
but it's hard to guess whether subclasses (other than TestCase) do.
We will assume they don't, unless they have a
``cleans_up_after_itself`` attr set to True. This is reasonable
because the odd behavior of TransactionTestCase is documented, so
subclasses should by default be assumed to preserve it.
Thus, things will get these comparands (and run in this order):
* 1: TestCase subclasses. These clean up after themselves.
* 1: TransactionTestCase subclasses with
cleans_up_after_itself=True. These include
FastFixtureTestCases. If you're using the
FixtureBundlingPlugin, it will pull the FFTCs out, reorder
them, and run them first of all.
* 2: TransactionTestCase subclasses. These leave a mess.
* 2: Anything else (including doctests, I hope). These don't care
about the mess you left, because they don't hit the DB or, if
they do, are responsible for ensuring that it's clean (as per
https://docs.djangoproject.com/en/dev/topics/testing/?from=
olddocs#writing-doctests)
