Why am I getting: can't locate node [rosout] in package [rosout]

edit

I am trying to run a rostest from catkin which was added with add_rostest()

It runs fine when started with a rostest call directly.

But when I try to run it from catkin I get ...

ERROR: failed to start core service [/rosout]   File "/usr/lib/python2.7/unittest/case.py", line 327, in run
    testMethod()   File "/home/aub-ch/ros/hydro_ws/src/my_navigation_test/rostest/tools/rostest/src/rostest/runner.py", line 121, in fn

    return self.runner.launch()   File "/home/aub-ch/ros/hydro_ws/src/my_navigation_test/rostest/tools/roslaunch/src/roslaunch/launch.py", line 644, in launch

    raise RLException("failed to start core service [%s]"%node_name)

And the log contains ...
