Testing

In order to successfully run the tests a ros node must be accessible with packages ros-{distro}-rosbridge-server and ros-{distro}-rospy-tutorials installed. And it must be running these three processes:

1. roscore
2. rlaunch rosbridge_server rosbridge_websocket.launch
3. rosrun rospy_tutorials add_two_ints_server
