I've been using it all my professional career; and I firmly believe it is the only way to develop software, a good test set really helps to move forward at a sustainable pace. Close attention should off course be payed to the quality of the tests also. You are right on the point that extensive testing does not give you a mathematical certainty that everything works, but having a good test set catches most of the bugs, certainly if you're adapting/refactoring an existing system: which is the goal of Pharo: evolve/refactor Squeak.
