By convention, a library meant for testing exports "run-tests". Also by convention, assume the test for (foo bar) is (foo bar-test), keeping the test in the same directory and avoiding confusion since (chibi test) is not a test for (chibi). - Avoids the hack of "load"ing test, with resulting namespace complications. - Allows keeping tests together with the libraries. - Allows setting up test hooks before running. - Allows implicit inference of test locations when using above conventions.
