Working with non-python tests
|
|
====================================================
|
|
|
|
.. _`yaml plugin`:
|
|
|
|
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
|
|

================================= FAILURES =================================
|
|
______________________________ usecase: hello ______________________________
|
|
usecase execution failed
|
|
spec failed: 'some': 'other'
|
|
no further details known at this point.
|
|
==================== 1 failed, 1 passed in 0.05 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. You can easily write
|
|
your own domain specific testing language this way.
|
|
|
|
.. note::
|
|
|
|
``repr_failure(excinfo)`` is called for representing test failures.
|
|
If you create custom collection nodes you can return an error
|
|
representation string of your choice. It
|
|
will be reported as a (red) string.
|
|
|
|
``reportinfo()`` is used for representing the test location and is also
|
|
consulted when reporting in ``verbose`` mode::
|
|
|
|
nonpython $ py.test -v

While developing your custom test collection and execution it's also
|
|
interesting to just look at the collection tree::
|
|
|
|
nonpython $ py.test --collectonly
