py.test plugin to list Python warnings in pytest report.

Integrated in pytest >= 3.1.0.


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.


# pytest.ini
filterwarnings= default
