Is it possible to set breakpoints in py.test tests?

PyCharm has support for running py.test tests. However it seems this support is very minimal as PyCharm does not offer an option to enter debugger on uncaught exceptions. I found plugin that does this – https://pypi.python.org/pypi/pytest-pycharm

However I'd like to be able to set breakpoints in tests which I can't find a way to do.
Does PyCharm support this and if not is there any bug for this?
