Comment 9 for bug 1422376

I think the difference between the upstream egg snapshot (which contains all source) and the Ubuntu packaged source (which does not container everything) is the problem here - looking at sys.path in a fresh venv:

>>> print sys.path
['', '/home/jamespage/src/upstream/neutron-fwaas/.tox/py27/src/neutron', '/home/jamespage/src/upstream/neutron-fwaas', '/home/jamespage/src/upstream/neutron-fwaas/.tox/py27/lib/python2.7', '/home/jamespage/src/upstream/neutron-fwaas/.tox/py27/lib/python2.7/plat-x86_64-linux-gnu', '/home/jamespage/src/upstream/neutron-fwaas/.tox/py27/lib/python2.7/lib-tk', '/home/jamespage/src/upstream/neutron-fwaas/.tox/py27/lib/python2.7/lib-old', '/home/jamespage/src/upstream/neutron-fwaas/.tox/py27/lib/python2.7/lib-dynload', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/home/jamespage/src/upstream/neutron-fwaas/.tox/py27/local/lib/python2.7/site-packages', '/home/jamespage/src/upstream/neutron-fwaas/.tox/py27/lib/python2.7/site-packages']

You can see that "/home/jamespage/src/upstream/neutron-fwaas/.tox/py27/src/neutron" is listed on the path - which includes all the neutron goodness required to execute the tests.

We don't have that in the Ubuntu distribution and would account for at least:

ConfigFilesNotFoundError: Failed to find some config files: /usr/lib/python2.7/dist-packages/etc/policy.json

as this is present in the generated egg, but not python-neutron.
