A test generation algorithm for systems modelled as non-deterministic FSMs

A variety of systems can be modelled as finite-state machines (FSM). Several formal methods have been proposed for testing the conformance of an implementation to a given FSM-based specification. However, all of these methods assume that the specification is modelled by a deterministic FSM. The paper presents an efficient algorithm that generates a set of adaptive all state-pair optimised distinguishing sequences for testing systems modelled as non-deterministic FSMs. >
