ABSTRACT
Three examples will be used throughout in Chapters 5 through 9 to illustrate the various unit testing methods: the triangle problem (a venerable example in testing circles); a logically complex function, NextDate; and an example that typifies MIS applications, known here as the commission problem. Taken together, these examples raise most of the issues that testing craftspersons will encounter at the unit level. The discussion of higher levels of testing in Chapters 11 through 17 uses four other examples: a simplified version of an automated teller machine (ATM), known here as the simple ATM system (SATM); the currency converter, an event-driven application typical of graphical user interface (GUI) applications; and the windshield wiper control device from the Saturn™ automobile. The last example, a garage door controller, illustrates some of the issues of “systems of systems.”
