Would it be beneficial to support tox (venv based tester), testr, and flake8 (similar to how openstack works) instead (or inconjunction with) the current testing frame works? If that kind of test environment would be beneficial, I would be happy to help set it up for both dogpile.cache and dogpile.core.
This could also allow for pep8/pylint testing.
Coupled with this, I would also be happy to do some of the pep8 restructuring (if that would be desired).
Personally I like the ability to run
tox -epep8 or
tox -epy27 to run the tests and see how long it takes for each test to run. It never hurts to ask.
