Can someone explain to me the *details* of how to use Test::Unit, preferably an example showing the source code to be tested, the test code, and any other glue or details necessary to make it all work? I've never done this before, and it isn't clear to me how you arrange your code and test-code so that your tests can be run automatically, quickly and often. Test harnesses I've used in the past require considerable effort to get started, and to use. TIA. -- Steve Merrick "Who cares, wins"
