.. _`non-python tests`:
Working with non-python tests
====================================================
a basic example for specifying tests in Yaml files
--------------------------------------------------------------
.. _`pytest-yamlwsgi`: http://bitbucket.org/aafshar/pytest-yamlwsgi/src/tip/pytest_yamlwsgi.py
.. _`PyYAML`: http://pypi.python.org/pypi/PyYAML/
Here is an example ``conftest.py`` (extracted from Ali Afshnars special purpose `pytest-yamlwsgi`_ plugin). This ``conftest.py`` will collect ``test*.yml`` files and will execute the yaml-formatted content as custom tests:
.. include:: nonpython/conftest.py
:literal:
You can create a simple example file:
.. include:: nonpython/test_simple.yml
:literal:
and if you installed `PyYAML`_ or a compatible YAML-parser you can
now execute the test specification::
nonpython $ py.test test_simple.yml
=========================== test session starts ============================
platform linux2 -- Python 2.6.5 -- pytest-2.0.0.dev17
test path 1: test_simple.yml
test_simple.yml .F
================================= FAILURES =================================
______________________________ usecase: hello ______________________________
usecase execution failed
spec failed: 'some': 'other'
no further details known at this point.
==================== 1 failed, 1 passed in 0.37 seconds ====================
You get one dot for the passing ``sub1: sub1`` check and one failure.
Obviously in the above ``conftest.py`` you'll want to implement a more
interesting interpretation of the yaml-values. Note that ``reportinfo()``
is used for representing the test location and is also consulted for
reporting in ``verbose`` mode::
nonpython $ py.test -v
=========================== test session starts ============================
platform linux2 -- Python 2.6.5 -- pytest-2.0.0.dev17 -- /home/hpk/venv/0/bin/python
test path 1: /home/hpk/p/pytest/doc/example/nonpython
test_simple.yml:1: usecase: ok PASSED
test_simple.yml:1: usecase: hello FAILED
================================= FAILURES =================================
______________________________ usecase: hello ______________________________
usecase execution failed
spec failed: 'some': 'other'
no further details known at this point.
==================== 1 failed, 1 passed in 0.07 seconds ====================
While developing your custom test collection and execution it's also
interesting to just look at the collection tree::
nonpython $ py.test --collectonly
<Directory 'nonpython'>
<YamlFile 'test_simple.yml'>
<UsecaseItem 'ok'>
<UsecaseItem 'hello'>
