We then end up with a big ol' pretty color-coded page of test results, so we can easily see where the problems are. Most of the problems with the tests will be with the tests themselves, but some will certainly help us find brokenness in MacPerl.
I want to get a lot of testing done in the next few weeks, and then I will have a much better idea of how close we are. I know there are some significant problems with the app, and there are surely lots of little problems with the Mac:: modules. But we are moving forward.
