ah damn. sorry, didn't think this would affect anyone. Does this mean that you would rather like to have the config argument passed in to not break your already released code?
it really an issue just with the tests, not the plugin, the attached patch fixes the issue in such a way that my own test doesn't need changes, it really fixes a bug in the hook recording infrastructure in pytestpytest which was never capable before of dealing with no args hooks
applied your patch, should be in 1.0.0b8. also added you to the writers/admins of this repo so that you can in the future directly commit such bits. don't hesitate - i'll read the commit/diff mails anyway.
