If you used older version of the
py distribution (which included the
py.test command line tool and Python name space) you accessed helpers
and possibly collection classes through the
py.test Python namespaces.
pytest Python module flaty provides the same objects,
following these renaming rules:
py.test.XYZ -> pytest.XYZ py.test.collect.XYZ -> pytest.XYZ py.test.cmdline.main -> pytest.main
py.test.* ways to access functionality remain valid but you
are encouraged to do global renaming according to the above rules in
your test code.
