I want to test *my* code, that I'm working on and actively changing. There's no contradiction between running tests on the code you are developing, while assuming (at least before evidence to the contrary) that the rest of the system is OK.

Yes I do ;) Zbyszek PS. PYTHONPATH=/usr/lib/python3.5/site-packages python3.4 -m pip also works... _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx
