You could look at how --fixtures is implemented, that's probably what I would follow if I wanted to do something similar. Search for "showfixtures" in _pytest/python.py. Basically add the option like normal in pytest_addoption() and then implement pytest_cmdline_main() to look for the option and handle it. If the option is not there just return None from it and the normal pytest will continue to run. Hope that helps, Floris _______________________________________________ pytest-dev mailing list pytest-dev@python.org https://mail.python.org/mailman/listinfo/pytest-dev
