Neutron uses tox as the defacto standard method for running unit tests. If
you don't have tox you install it like this:

  sudo pip install -U tox==1.6.1

The version locking is required because of some incompatibility with newer
versions. (The incompatibility may be fixed, but I am still using 1.6.1.)

To run unit tests:

  # all neutron unit tests (takes a very long time)
  tox -e py27

  # just the tests in test_l3_agent.py
  tox -e py27 neutron.tests.unit.test_l3_agent

Using run_test.sh is intended to work but if there are problems with it they
are sometimes discovered late because fewer people use it. That said, I just
ran the following and had no problems:

  ./run_tests.sh neutron.tests.unit.ml2.test_ml2_plugin

However, before this I had already run tox, which create a virtual
environment which run_tests.sh seems to pick up.

If you want to discuss more details of neutron unit tests feel free to post
your questions to the openstack-dev mailing list with [neutron] in the subject.
