thanks, i see. I think you could as well just do it once in a conftest.py file and avoid the dynamic discovery. The Python import system caches imports so all subsequent modules importing "scripy" would pick up the previously imported one. Either way this makes it harder to run tests against the installed version of a package - which is nice to for checking if everything is correctly installed, i.e. no files, data etc. missing. Hum, we could think about adding a call to a new pytest_addsyspath() hook that could be put in a conftest.py file (and you could statically add ../lib to sys.path in your project) - and also introduce an option "--no-addsyspath" to prevent py.test from calling this hook. This should work and help projects to make things properly available during development but also run tests against an installed package.
