Where is catkin_add_nosetests() documented?
Apparently, that is the catkin way to run Python unit tests.
I can't find any documentation for it via Google.
UPDATE: For future reference: Dirk found it under Development Documentation.
+1. For Hydro it might be http://docs.ros.org/hydro/api/catkin/html/dev_guide/generated_cmake_api.html#catkin-add-nosetests
