JML-testing-tools: A symbolic animator for JML specifications using CLP

This paper describes a tool for symbolically animating JML specifications using Constraint Logic Programming. A customized solver handles constraints that represent the value of instance fields. We have extended a model-based approach to be able to handle object-oriented specifications. Our tool is also able to check properties during the simulation and exhibit counter-examples for false properties. Therefore, it can be used both for semi-automated verification and for validation purposes. © Springer-Verlag Berlin Heidelberg 2005
