Assuming WorkspacesAPITest does actually have an attribute named lab_config then you'll want to add the installed package to the python path during the check phase. There are a number of packages which do this. I can never remember the syntax so I always grep for 'add-installed-pythonpath' when it comes up. > I guess I will summarize everything in the end and put it in a > repository as a kind of "guide", so that others can use it or learn from > the process.
