Hi, I would like to play back the bag files produced by making 'test' : icra_navigation_gazebo.rostest__worlds_blind_corner_blind_corner.bag icra_navigation_gazebo.rostest__worlds_door_and_table_door_and_table.bag icra_navigation_gazebo.rostest__worlds_obstacle_slalom_obstacle_slalom.bag How can I do that ? I am supposing that the bag files (into the folder ~/.ros/test_results/ros_epic_fail_raw_bags$) above contains the simulation executed by $ make test . Juracy
