Sometimes the usual way is not very helpful, especially when you are working on some new code and say running into issues importing code. Then, here’s what you do.
First, activate the py27 virtualenv

| dims@dims-mac:~/openstack/nova$ . .tox/py27/bin/activate |
Then use testtools

| (py27)dims@dims-mac:~/openstack/nova$ python -m testtools.run nova.tests.unit.test_versionsTests running...Ran 2 tests in 0.090sOK |
Or you can install pytest

And then run the same test using py.test
