Comment (by Adam Zapletal):
I appreciate your insight here. Please know that I wasn't questioning your
approach...I'm just trying to understand the problem!
----
One point of clarification on this comment:
> Thanks for the grep -- it's true Django itself only has one test case
class in this situation, but a user could be doing this. I think there
would have been a similar problem with SeleniumTestCase if it were
supported by the parallel test runner. (It doesn't today but might in the
future.)
I was assuming that in a real project (not Django itself), the user
wouldn't have this problem. They'd be opting into setting `available_apps`
on their test class, so we can expect them to do it correctly. The
attribute is only required
[https://github.com/django/django/blob/8bee7fa45cd7bfe70b68784314e994e2d193fd70/tests/runtests.py#L314
in Django's test suite].
When I remove the linked check from `runtests.py` or set `available_apps`
to `None`, the test in question passes.
----
I'd like to hear from others as well. Do you want to ping people on this
ticket, or should we open a forum thread?
