Comment (by julien):
For the record, I think this is just a symptom of a deeper problem, i.e.
that Django doesn't provide a clean environment for unit tests to be run
in. Other examples of such symptomatic issues are: #17194, #13394, #16366,
#10976, #8404, #16413, and many more. Whatever we do to fix those symptoms
we will always keep finding more and more of them — this just has no end
as it's impossible to predict all the combinations of settings people
might use in the wild with their projects. Patching those tests with
little fixes does make them more isolated, but it also does make the tests
harder to read as it increases the amount of boilerplate code inside the
tests, without doing anything really useful like increasing the code
coverage or fixing actual bugs in the tested code.
As stated earlier in this thread, I see no reason for running the Django
contrib apps from one's project with '`manage.py test`' at all. Those
tests are already run by the CI server, and running them from your project
will add no value to you. They can only cause annoyances when they fail
because of isolation problems. This is why I recommend to simply ignore
those tests and not run them from your project.
I contend that our energy would be better spent focusing on finding a more
general solution to the root cause. I don't think much work has been done
in that area yet. I know at least of #9156 addresses that.
