I don't see how it's either one.  An explanation would be helpful.

Note, by the way, that setuptools is not particularly designed to 
support running tests against an installed package; I myself have 
stopped distributing tests in installed packages and require a source 
installation (e.g. using easy_install --editable) to run tests.

This pattern is particularly important for reducing runtime 
installation requirements, as tests often require additional packages 
(such as nose itself) in order to run.
