It would be amazing if core functionality had some kind of unit test framework attached, so that if someone goes and does something radical, like reworking board access, you can have methodology to prove it isn't broken. (And if it does break and it wasn't caught by the tests, fix it then add a new test)
I'm not quite sure what any of that means....
It is nothing that a user would see....I understand what he's asking about and, yes, it would be great...
Test frameworks are a great resource saver for testing
System Restore ???.
(LOL :D)
