Jurko Gospodnetić 9fb2079458 replace py.test module references with pytest
The only remaining 'py.test' references are:
 * those referring to the 'py.test' executable
 * those in code explicitly testing py.test/pytest module compatibility
 * those in old CHANGES documentation
 * those in documentation generated based on external data
 * those in seemingly unfinished & unmaintained Japanese documentation

Minor stylistic changes and typo corrections made to documentation next to
several applied py.test --> pytest content changes.

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
* 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://bitbucket.org/hpk42/pytest/issue/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://bitbucket.org/hpk42/pytest/issue/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
