The importance of software testing and its implications with respect to software quality cannot be overemphasized. To quote Deutsch ,

The development of software systems involves a series of production activities where opportunities for injection of human fallibilities are enormous. Errors may begin to occur at the very inception of the process where the objectives . . . may be erroneously or imperfectly specified, as well as [in] later design and development stages . . . Because of human inability to perform and communicate with perfection, software development is accompanied by a quality assurance activity.

Software testing is a critical element of software quality assurance and represents the ultimate review of specification, design, and code generation.

The increasing visibility of software as a system element and the attendant "costs" associated with a software failure are motivating forces for well-planned, thorough testing. It is not unusual for a software development organization to expend between 30 and 40 percent of total project effort on testing. In the extreme, testing of human-rated software (e.g., flight control, nuclear reactor monitoring) can cost three to five times as much as all other software engineering steps combined!

Software testing fundamentals define the overriding objectives for software testing. Test case design focuses on a set of techniques for the creation of test cases that meet overall testing objectives.
