“Testing gathers information about a product; it does not fix things it finds that are wrong. Testing does not improve a product; the improving is done by people fixing the bugs that testing has uncovered. Often when managers say, “Testing takes too long,” what they should be saying is, “Fixing the bugs in the product takes too long”—a different cost category.”
