Speaker: Michiel van Osch (FM, TU/e) Title: Automated Model-based Testing of Hybrid Systems Abstract: Model-based test theory, like the input-output conformance relation of Tretmans, and tools, like TorX, for discrete event testing have been around for some years now. Recently theories for timed testing and symbolic testing have been defined also. These theories and tools do not deal with continuous aspects of a system. We have adapted Tretmans' formal input-output conformance relation to the setting of hybrid transition systems. Furthermore, we have formalized the notions of test and test execution for hybrid transition system. With every hybrid transition system we associate a set of tests, which is sound and exhaustive: if an implementation is conform a specification, then there is no test that (when performed on the implementation) leads to a fail verdict (soundness); and if an implementation is not conform a specification; then a test can be defined that (when performed on the implementation) leads to a fail verdict (exhaustiveness). Currently we are implementing our hybrid test theory in a test tool based on the hybrid chi tool set. In this presentation I give an overview of our hybrid test theory and I present the latest developments on the implementation of this theory.
