I'm not sure where you heard that from, but even the name itself should already have given it away -- it's *unit* testing, not global testing. Even in the best, most ideal case, you can only prove things about that *unit* of code, it says nothing about what happens when you put them together to form the entire system. There are many ways to put perfectly-functioning components together that results in a malfunctioning system. Also, while unittests do help to catch many bugs, it's certainly not an "anti-bug" design. There is no such thing! As we all (should) know, there is no such thing as a bug-free system. The best you can do is to reduce the total number of bugs; by their very nature, complex systems are far too complex for us to fully weed out every possible failure. Anyone selling this or that methodology as the be-all and end-all of solving your bug woes is merely pandering snake oil. :-D > I think they should be used sensibly not everywhere. Certainly.
