python tests not deployed

I wrote a test that inherits from a built-in test, but it fails on my build server. When comparing the dev environment with the build server, and I get the following difference:

Dev environment (mac):

>>> len(os.listdir(os.path.dirname(test.__file__)))
1418

Build server (linux):

>>> len(os.listdir(os.path.dirname(test.__file__)))
8

Basically, when installing Python, it didn't deploy its test files. How do I fix this?

Thanks!
