Abstract

Model-based testing automatically generates test cases from a model describing the behavior of the system under test. Although there exist several model-based formal testing methods, they usually do not address time constraints, mainly due to the fact that some supporting formalisms do not allow a suitable representation of time. In this paper, we consider such constraints in a framework of Timed Extended Finite State Machines (TEFSMs), which augment the Extended Finite State Machine (EFSM) model by including a notion of explicit and implicit time advancement. We use this extension to address conformance testing by reducing the confirming configuration problem to the problem of finding a path in a TEFSM product.
