 <p>No test suite, including CTS, can truly be comprehensive. For instance, the
 CTS includes a test that checks for the presence and correct behavior of
 OpenGL graphics APIs, but no software test can verify that the graphics
 actually appear correctly on the screen. More generally, it's impossible to
