Actually, I would be shocked if the present unit tests cover all the edge cases. But this is *not* a gotcha. It simply means that: 1. When there is the *slightest* doubt about the legacy code does, a unit test should be created to find out. 2. All bugs reported against the new code should require a new unit tests (or improved existing test) before we can call the bug fixed. These two principles will ensure that the new code will eventually become equivalent to the old.
