The National Institute of Standards and Technology (NIST) has estimated that software bugs cost the U.S. economy approximately $60 billion each year. An NIST study found that “more than a third of these costs, or an estimated $22.2 billion, could be eliminated by an improved testing infrastructure that enables earlier and more effective identification and removal of software defects.” The study is clear on this point: during the early stage of the development lifecycle, thorough and frequent testing of each unit of code is crucial to reduce logic errors across an application.
