Activate move base recovery behaviors

Dear ROS users, I am writing a nav_core recovery plugin to use with move_base and the trajectory rollout planner. To effectively test my code, I would like to be able to trigger the recovery behavior in someway, or tell the planner to activate a recovery often. In fact, when the robot is stuck, recovery behaviors are not always activated. I tried to lower the value of controller_patience in move base, but it seems that does not work. Is there a way to tell the planner to activate the recovery behaviors?
