+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
+
+
+Changes
+=======
+
+0.1 - Unreleased
