Behavioral Conformance Verification in an Integrated Approach Using UML and B

We propose an integration of diagrammatic object oriented modeling techniques with a formal specification and verification technique. We translate UML class diagrams to B abstract machines in a way that does not only provide a formal interpretation of the class diagrams but that also allows us to verify properties of object oriented models within the framework of the B method. Specifically, we address translating generalization / specialization hierarchies to B. An appropriate construction of B components allows us to express and formally verify behavioral conformance, which ensures that polymorphism can be used safely. Expressing the proof obligations associated with behavioral conformance by constructing B components makes it possible to use the tool AtelierB for mechanically verifying them.
