how to pass topic message via launch_test with ros2
i want to launch a node via launch_test command , and pass argument(through the topic message) to the node to test whether it is correct, how to do it? (i have already check the link: https://github.com/ros2/launch/tree/m..., it seems can't pass argument through topic) or is there other way to achieve the requirement? thank very much!
