Segmented State Space Traversal for Conformance Testing of Cyber-Physical Systems
Quantitative conformance testing of Cyber-Physical System (CPS) exploits time series of measurements, such as temperature or energy, for validating the correctness of deployed systems. This paper presents the foundations of segmented state space traversal in the setting of quantitative conformance testing of a CPS. It is demonstrated how this strategy together with domain-specific adaptations remedies state space explosion inherent to formal (state-based) verification. The presented contributions improve the scalability of quantitative conformance testing of a CPS and is demonstrated with a case study.
