How delete run/test configurations in pycharm?

I just moved a directory in my pycharm project that had tests in it. Now the tests fail because the run configuration for them points to the old missing directory. I see I can manually edit each test to use the new directory, but how do I do this all at once, or just delete these runs configurations so that new ones get created with the correct paths? Maybe this is a bug in pycharm? That is, pycharm kept run configurations for the moved tests, but it did not update the paths?
