Abstract

Automated test data generation is an important method for the verification and validation of UML/OCL specifications. In this paper, we present an extension of DNF-based test case generation methods to class models and recursive query operations on them. A key feature of our approach is an implicit representation of object graphs avoiding a representation based on object-id's; thus, our approach avoids the generation of isomorphic object graphs by using a concise and still human-readable symbolic representation.
