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.
The new 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
The old 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.
