Hi, I'm currently struggling to find a good way for running unit tests in my project. Adding a custom Command to my setup.py for running the tests wouldn't be a big problem but the unit tests need a few additional shared libraries. These libraries are simple stub files used for testing the plugin loader I'm developing. So is there a way to tell distutils to build those shared libraries only if want to run the unit tests? Otherwise those libs should be ignored because I don't want them to be installed generally. Thanks for the help Johannes
