Abstract

ult-based testing strategies generate tests to detect faults belonging to a preselected set of simple fault classes. A hierarchy of fault classes and the infrequency of fault coupling let us rely on these strategies to detect many other faults, too.For Boolean specifications, Kuhn proved that there is a hierarchy of fault classes with respect to detectability. This implies that some fault classes may be ignored during test generation. We prove that Kuhn's hierarchy holds for a general form of Boolean specifications, then consider detectability of another fault class.Fault coupling occurs when a test set can detect faults in isolation, but not in combination; a low incidence of fault coupling is desirable. Using Kuhn's technique, we show that fault coupling does not occur for some important fault classes in expressions containing a restricted set of Boolean operators.
