to eject a CD driver, or a Web service to delete a cached file in the/tmp directory, or a socket service to bind a TCP port, these calls are not expected when you unit tests. As a developer, you're more concerned about whether your library has successfully invoked a system function to eject a CD, rather than experiencing a CD tray opening every time you test. As a developer, you are more concerned about whether your library successfully invokes the system function to eject the CD (with the co
