In addition to traditional file system path test discovery it is
useful to run a test by stating it's dotted python path. For example,
this will only run the cmdmod integration tests from the
module suite::
$ runtests.py -n tests.integration.modules.cmdmod
tempfile.gettempdir() is way better. The gem and rvm states are
still failing, but only because they require the "mock" python
module for running their tests.
Integration tests requiring a salt master and daemon were seperated
from pure unit tests. For now both are run with runtest.py. In
the future it could take arguments for which type of tests to run.
