Quality Assurance in MBE Back and Forth

Abstract

The maturing of model-based engineering (MBE) has led to an increased interest and demand on the verification of MBE artifacts. Numerous verification approaches have been proposed in the past and, in fact, due to their diversity it is sometimes difficult to determine whether a suitable approach for the verification task at hand exists. In the first part of this tutorial, we thus present a classification for verification approaches of MBE artifacts that allows us to categorize approaches, among others, according to their intended verification goal and the capabilities of their verification engine. Based thereon, we briefly overview the landscape of existing verification approaches. In the second part, we iteratively build and verify the behavioral correctness of a small software system with our OCL-based model checker MocOCL..
