Code review comment for lp://staging/~barry/piston-mini-client/lp1077083

Note that you will have some trouble testing this on today's Raring. The problem is that tox is not yet in Raring (it will soon land in Debian and then be synced to Raring), and the python-virtualenv version that is currently in Raring is not compatible with Python 3.3. This should be fixed upstream today and will make it into Ubuntu shortly thereafter.

To test this on Raring, your best bet is to install virtualenv from upstream git (where the Python 3.3 bug is fixed), create a Python 2.7 and separate Python 3.3 virtualenvs, install the dependencies into them (via pip), and then run nosetests into the virtualenv.

Hopefully by next week you'll be able to just run `tox -e py27,py33` in Raring.
