This is useful when to use regular expressions, like for example ignore
a bunch of dynamic messages
--filterwarnigns 'ignore:Please use assert.* instead.:'
Or ignore all the warnings in a sub-backage
--filterwarnigns 'ignore:::package.submodule.*'
This is also available in the ini file as the filterwarnigns options
pytest-warnings
===============
py.test plugin to list Python warnings in pytest report
Usage
-----
install via::
pip install pytest-warnings
if you then type::
py.test -rw
any warnings in your code are reported in the pytest report.
You can use the ``-W`` option or ``--pythonwarnings`` exactly like for the ``python`` executable.
The following example ignores all warnings, but prints DeprecationWarnings once per occurrence::
py.test -rw -W ignore -W once::DeprecationWarning
You can also turn warnings into actual errors::
py.test -W error
Advance usage
=============
You can get more fine grained filtering of warnings by using the
``filterwarnings`` configuration option.
``filterwarnings`` works like the python's ``-W`` flag except it will not
escape special characters.
Example
-------
.. code::
# pytest.ini
[pytest]
filterwarnings= default
ignore:.*is deprecated.*:Warning
error::DeprecationWarning:importlib.*
