OpenStack Hint of the Day: Wed Apr 29

When running tox and you get something like this:

mrda@garner:~/src/python-ironicclient (review/michael_davies/file-caching)$ tox -e py34
py34 runtests: PYTHONHASHSEED='3098345924'
py34 runtests: commands[0] | python setup.py testr --slowest --testr-args=
running testr
running=OS_STDOUT_CAPTURE=${OS_STDOUT_CAPTURE:-1} OS_STDERR_CAPTURE=${OS_STDERR_CAPTURE:-1} ${PYTHON:-python} -m subunit.run discover -t ./ ${OS_TEST_PATH:-./ironicclient/tests/unit}  --list 
db type could not be determined
error: testr failed (3)
ERROR: InvocationError: '/home/mrda/src/python-ironicclient/.tox/py34/bin/python setup.py testr --slowest --testr-args='
________________________________________________________________________________________________ summary _________________________________________________________________________________________________
ERROR:   py34: commands failed

The solution is to "rm -rf .testrepository/" and try again.
