I have a suite of App Engine tests that are called using nose. When I run them from a terminal, every test completes successfully and all reports, like coverage, are generated.
However, if I try to call the same command from Hudson, I get the following failure from coverage:
nose.failure.Failure.runTest (from Failure)
Parent module 'coverage' not loaded

However, if I remove the call to coverage, my tests still fail.
I’ve succesfully run Python projects with Hudson. Is there a GAE nuance that’s tripping me up?
Compare the environments when you run it manually to when you run it using hudson.
I suspect that the initialization happens within the .profile file. That is not called when Hudson spawns a shell. So either you put this initialization into the environment initialization or you call the .profile file manually within the effected build steps.
