Automata Based Test Generation with SpecPro

In this paper we introduce a new automata based test generation algorithm implemented in SPECPRO, our library for supporting analysis and development of formal requirements in cyber-physical systems. We consider specifications written in Linear Temporal Logic (LTL) from which we extract automatically trap properties representing the expected behaviour of the system under development. With respect to manual generation, the main advantage of SPECPRO is that it frees the developer from the burden of generating tests in order to achieve stated coverage targets. Our goal is to have SPECPRO handle specifications of small-but-critical components in an effective way.
