TDD helps us speed up by reducing the time it takes to fix defects. It is common sense that fixing a defect two months after its introduction into the system takes time and money—much more than fixing it on the same day it was introduced. Whatever we can do to reduce the number of defects introduced in the first place, and to help us find those defects as soon as they’re in, is bound to pay back.
