Many other python libraries provide some kind of testing command in their setup.py file. That means you just type:
>> python setup.py test
and all tests will be performed. The nice thing is that the path is automatically set to the right version of puremvc on your computer and so it is easy to have e.g. a stable one installed and another development version somewhere in the filesystem and can test the right one with just on command.
The modification of the setup.py file and a small modification in the unittest/main.py file can be found on github: http://github.com/bastikr/python-puremvc/tree/master/trunk/
If this feature is wanted I can also send some kind of patch.
