rostest kills roscore

edit

I created a gtest test class for obvious reasons. I made the necessary adjustments to CMakefile.txt, and the package builds both the node and test executables fine. When I run 'make test', the tests complete with no failures. Then, I made a test launch file (armMotion.test) that contains the following:

<launch>
<test test-name="arm_motion_test" name="arm_motion" pkg="arm_motion" type="utest" time-limit="180"/>
</launch>

In the terminals that I will run this test file and my roscore, I change the ROS_URI_MASTER port to 22422. Then, I perform the command 'rostest --text armMotion.test'. As soon as I execute this, my roscore dies. From the master.log file:

" ... [INFO] 2011-07-07 19:15:35,639: +SUB [/LowerPanTilt/start_velocity_control] /LowerPanTilt/LowerPanTilt http://darpa-arm-gfe:41147/

In another log file: "
