I think more has to be done to make us pytest-compatible, lots of the tests are getting skipped that shouldn't be.

Note that the setup.py entrypoint does some extra work here.

I believe the equivalent of the setup and teardown functions will need to be done in a conftest.py fixture:

def pymongo_test_fixture(scope='session', autouse=True):
      # do setup stuff
      yield
      # do teardown stuff

Latest commit should address this, I've added a session-level autouse fixture to perform the setup and teardown found in the test module __init__.

Very nice!

is it possible to refer to extras here so we don't need to duplicate the dependencies? like .[encryption]?

Yeah that should work

Fixed, thanks!

Nice LGTM!
