Testing with rosmake -a -t fails because a test failure failed to launch. What's wrong?
Running 'rosmake -a -t' I get some test failures attributed to 'Test Fixture Nodes ['xxx'] failed to launch. How can I determine what's wrong and fix it?
An abbreviated example:
ERRORS/FAILURES:
[robot_pose_ekf.rostest__test_test_robot_pose_ekf_zero_covariance/testtest_robot_pose_ekf][FAILURE] Test Fixture Nodes ['rosbag'] failed to launch <snip> PACKAGES: * robot_pose_ekf
