I have a Django app called “fstore”. It’s registered in INSTALLED_APPS as “foo.bar.fstore”. When I run all of my django tests via “manage.py test”, I see results from its test, eg.:

FAIL: testFilesWithDuplicatePathsDoNotOverwriteEachOther
(foo.bar.fstore.tests.fileRecTests.TestFunctionality)

However, when I try to specifically run tests for this app, via “manage.py test fstore”, Django tells me:

Ran 0 tests in 0.000s

If I had the app name wrong or something it would give me an error, but it clearly recognizes the app … it just fails to find the tests for it (even though they’re inside a “tests” folder with an __init__.py inside that app’s folder). So my basic question is: what gives? Or more specifically, how do I get just the tests from this app to run without running all of the rests?

Oh, and just to rule out the easy answer, yes this app has both a models.py and an __init__.py.

* EDIT *

I just ran “manage.py shell” and it turned out something was fishy:

from django.db.models import get_app, get_apps
get_app("fstore")
<module 'foo.bar.search.models' from '/baz/python/foo/bar/search/models.pyc'>

Which of course was the compiled form of the completely wrong model (no clue how that happened). So I removed the .pyc file, and now I get a more normal error:

django.core.exceptions.ImproperlyConfigured: App with label fstore
could not be found

which is progress … but it still doesn’t explain why Django can’t find my app.

One more note: even though Django works fine (I can “manage.py runserver”, browse around my app, etc.), at the command line I apparently have no apps at all. For instance, trying to run “manage.py test debug_toolbar” gives me a similar ImproperlyConfigured error. Hopefully this means something to someone …

    Wow, this was terrible. So I guess I’ve been editing Django core files in my sleep or something, because there was a file (models/loading.py) which had been modified to have that foo.bar.search app hard-coded in to it. I don’t have any bash history of editing this file, nor do I have an Eclipse history, and I would have had no reason to edit the file, but … since no one else could have done it, I guess I must have (or else there is a REALLY weird django bug that results in it editing source code).

    I guess I’ll leave this question/answer here on the freak chance that someone else does something similar and this helps them, but this is such a freak occurrence that I doubt it will.
