django-pluggable
runtests.py
Your pluggable Django app will probably need to run an instance of Django
to be tested. runtests.py
does that for you.
Install from pypi:
$ pip install django-pluggable
Then run:
$ export PYTHONPATH=`pwd`; runtests.py --settings='path.to.test_settings'
All apps that are in INSTALLED_APPS
in your test settings will be tested.
