If I understood correctly, testr first loads all modules and then filter the tests to run using the regex passed on the command line. If I'm correct, I don't see right now how to run Olso Incubator tests with testr on Python 3. But I don't know well the Testr tool, so I missed probably an option.

Mehdi actually reminded me why we aren't using testr already: 
http://lists.openstack.org/pipermail/openstack-dev/2014-April/032202.html

It might still be possible to implement using the test discovery feature 
of testr to remove the bad tests before testr even gets them (see 
https://github.com/openstack/diskimage-builder/blob/master/diskimage_builder/tests/test_elements.py 
), but I don't have much experience with that so I can't say for sure 
whether it would work either.

Also, I believe Mehdi had a change proposed to address the problems 
running testscenarios in nose.  I think the patch is still waiting for a 
merge though:
