There is also pytest runner.

https://pypi.python.org/pypi/pytest-runner

My only complaint is that it installs pytest with an egg in the local
directory. That can make it easy to miss dependencies at times because they
may exist in the directory but not in the venv. I think that is a
setuptools pattern. It is not a huge deal, but it helps to be aware of it.
