Automatic Test Case Generation from UML Sequence Diagram

This paper presents a novel approach of generating test cases from UML design diagrams. Our approach consists of transforming a UML sequence diagram into a graph called the sequence diagram graph (SDG) and augmenting the SDG nodes with different information necessary to compose test vectors. These information are mined from use case templates, class diagrams and data dictionary. The SDG is then traversed to generate test cases. The test cases thus generated are suitable for system testing and to detect interaction and scenario faults.
