A Game-Theoretic Approach to Real-Time System Testing

This paper presents a game-theoretic approach to the testing of uncontrollable real-time systems. By modelling the systems with timed I/O game automata and specifying the test purposes as Timed CTL formulas, we employ a recently developed timed game solver UPPAAL-TIGA to synthesize winning strategies, and then use these strategies to conduct black-box conformance testing of the systems. The testing process is proved to be sound and complete with respect to the given test purposes. Case study and preliminary experimental results indicate that this is a viable approach to uncontrollable timed system testing.
