Okay, I found the problem. In my tests I'm importing models, with something
like:
from models import ...
That works when tests.py is located at the root of the app, that is: at the same
level as the models module.
But when splitting tests.py into individual files into tests/, models can't be
imported anymore. For it to work, I must use :
from my_app.models import ...
And now it works. The real problem here is that Django current behaviour is
silent failure, no error.
A little debugging led me in django.test.simple.get_tests() (at r12555 line 65):
try:
app_path = app_module.__name__.split('.')[:-1]
test_module = __import__('.'.join(app_path + [TEST_MODULE]), {}, {},
TEST_MODULE)
except ImportError, e:
# Couldn't import tests.py. Was it due to a missing file, or
# due to an import error in a tests.py that actually exists?
import os.path
from imp import find_module
try:
mod = find_module(TEST_MODULE,
[os.path.dirname(app_module.__file__)])
except ImportError:
# 'tests' module doesn't exist. Move on.
test_module = None
Here the __import__ fails, not because the tests module is missing, but because
the tests module fails to import another module.
And then, the find_module() fallback fails too: my debugging shows that
os.path.dirname(app_module.__file__) points to /path/to/myapp/models and *not*
to /path/to/myapp as it should be.
This could be caused by the fact that my models are also split into models/,
thus dirname() returns a bogus value. But app_path above is correct, since it
doesn't rely on the fact the models module is a file...
Hum.. My head hurts ;)
