Testing reusable apps

[Tomek Paczkowski]

Hi, I cannot find any good source on how test reusable apps. I poked around and found out that people (django-registration, south) tests on blank project.

This seems kind of wrong having to make some outside directory to be able to run tests.

Isn't there any better way?

I think so: I like to use the testing mechanism in
setuptools/distribute and run tests via `python setup.py test`.

Eric Holscher wrote about the approach:
http://ericholscher.com/blog/2009/jun/29/enable-setuppy-test-your-django-apps/.

A good example in some code I've written is
https://github.com/revsys/django-fack. The important parts are in
setup.py, which does::

...
test_suite = "fack._testrunner.runtests",
tests_require = ["mock"],
...

So then fack/_testrunner.py is the test harness itself.

You also might want to check out the tox.ini there too. Tox
(http://tox.rtfd.org/) automates testing against multiple Python
versions (and other types of variable dependencies) and can smooth out
some of the steps in getting quality repeatable testing working.
