For the "parameter ignore", here is an example with Oslo Incubator (which uses testr, at least for Python 2):

$ tox -e py27
...
FAIL: tests.unit.test_timeutils.TestIso8601Time.test_west_normalize
...
Ran 8675 (+8673) tests in 16.137s (+16.083s)
...

$ tox -e py27 tests.unit.test_timeutils.TestIso8601Time.test_west_normalize 
...
FAIL: tests.unit.test_timeutils.TestIso8601Time.test_west_normalize
...
Ran 8675 (+8455) tests in 17.250s (-39.332s)

Oslo Incubator runs unit tests using nosetests. I tried to use testr, but it fails on Python 3 because the openstack.common.eventlet_backdoor module cannot be loaded (eventlet is not available on Python 3).

How can I ignore openstack.common.eventlet_backdoor using testr? I understood that testr first loads all modules and then filter them using the regex.
