| Running tests written for nose |
| ======================================= |
| |
| .. include:: links.inc |
| |
| ``pytest`` has basic support for running tests written for nose_. |
| |
| .. _nosestyle: |
| |
| Usage |
| ------------- |
| |
| After :ref:`installation` type:: |
| |
| python setup.py develop # make sure tests can import our package |
| py.test # instead of 'nosetests' |
| |
| and you should be able to run your nose style tests and |
| make use of pytest's capabilities. |
| |
| Supported nose Idioms |
| ---------------------- |
| |
| * setup and teardown at module/class/method level |
| * SkipTest exceptions and markers |
| * setup/teardown decorators |
| * yield-based tests and their setup |
| * ``__test__`` attribute on modules/classes/functions |
| * general usage of nose utilities |
| |
| Unsupported idioms / known issues |
| ---------------------------------- |
| |
| - unittest-style ``setUp, tearDown, setUpClass, tearDownClass`` |
| are recognized only on ``unittest.TestCase`` classes but not |
| on plain classes. ``nose`` supports these methods also on plain |
| classes but pytest deliberately does not. As nose and pytest already |
| both support ``setup_class, teardown_class, setup_method, teardown_method`` |
| it doesn't seem useful to duplicate the unittest-API like nose does. |
| If you however rather think pytest should support the unittest-spelling on |
| plain classes please post `to this issue |
| <https://github.com/pytest-dev/pytest/issues/377/>`_. |
| |
| - nose imports test modules with the same import path (e.g. |
| ``tests.test_mod``) but different file system paths |
| (e.g. ``tests/test_mode.py`` and ``other/tests/test_mode.py``) |
| by extending sys.path/import semantics. pytest does not do that |
| but there is discussion in `issue268 <https://github.com/pytest-dev/pytest/issues/268>`_ for adding some support. Note that |
| `nose2 choose to avoid this sys.path/import hackery <https://nose2.readthedocs.org/en/latest/differences.html#test-discovery-and-loading>`_. |
| |
| - nose-style doctests are not collected and executed correctly, |
| also doctest fixtures don't work. |
| |
| - no nose-configuration is recognized |
