Unable to run a subset of tests using tox

[Taylor Peoples]

If I try to run a subset of tests using tox, such as:

tox -v -e py27 -- openstack_dashboard.test.api_tests.network_tests

I get an error from the manage.py command complaining about unrecognized arguments:

Fix proposed to branch: master

[Richard Jones (r1chardj0n3s)]

Confirmed the bug - it means we can't restrict tests to a specific set (or specific singular test) using the tox command, which is a show-stopper for removing run_tests.sh in my view.

Change abandoned by Richard Jones (<email address hidden>) on branch: master
Review: https://review.openstack.org/330868
Reason: I think 322016 is a superior patch to mine, retracting this one.
