For easier understanding of tests organisation, each filename should reflect the test it contains. e.g.: action_client.rs => test_ros_client_zenoh_action.rs.
For topics.rs that contain 2 tests, maybe test_pub_sub.rs.

I think the _action/feedback topic should also be tested. But that could come later in a separate PR.

It makes sense to me. I've renamed the file.

I agree with you. I've added a TODO comment in the code for the future update.
