I think the test discovery programs "py.test" and "nose" do what you 
want. If I understand you correctly you want something that sets the 
right search path for library modules. 
http://codespeak.net/py/dist/test/
http://somethingaboutorange.com/mrl/projects/nose/0.11.1/

You could also tweak the environment variable "$PYTHONPATH" or the 
variable "sys.path".
See section 6.1.2:
http://docs.python.org/tutorial/modules.html

I use "py.test" and like it. But I keep tests and libraries in the 
same directory. I know however that "py.test" also supports separate 
directories for tests.
