It is not hard to find that you can consider using simulation: Whether you want to write a script to pop up a cddriver or a web service to delete the cache files under the/tmp directory, or a socket service to bind a TCP port. These calls are not expected during unit testing. As a developer, you are more concerned about whether your library has successfully called the system function to pop up the CD instead of opening the CD
