Write your code to separate the finding of entry points, from the
*processing* of entry points. Then pass in manually-created EntryPoint
instances to test the processing routines.
Alternately, pass a mock WorkingSet to your routines that find entry
points. That is, write them like this:
def some_routine(working_set=pkg_resources.working_set):
for blah in working_set.iter_entry_points('whatever'):
...
And then just pass in a mock object for testing, that yields the EntryPoint
instances you want to test.
