The test doesn’t end and get back to the prompt, seems to be in a hanged state and didn’t output the xml file.
It’s the same behavior for every unit test launch.
I’ve just tested this and you’re right. For some reason, the test is not ending normally. I will have a look into this. For now, the trick you can do is to get back to the Shell using Ctrl+Z . However, the test results (the xml file) should be generated properly. You should have it at /home/user/.ros/test_results/robot_control.
