Abstract

The paper suggests a method for synthesis of adaptive tests with guaranteed coverage for checking functioning of discrete systems whose behavior is described by nondeterministic finite state machines. In contrast to other known methods, we do not represent the complete test as a tree but list test cases one by one and check functioning of the finite state machine on each test case. The complete test detects all defective systems that are r-distinguishable from the reference system. Besides, the test detects other defective systems containing traces that are not present in the specification; but detection of all such systems that are r-compatible with the specification is not guaranteed.
