MANTra: Towards Model Transformation Testing

Model-driven development is gaining importance in software engineering practice. This increasing usage asks for a new generation of testing tools to verify correctness and suitability of model transformations. This paper presents a novel approach to unit testing QVT Operational (QVTO) transformations, which overcomes limitations of currently available tools. Our proposal, called MANTra (Model transformation Testing), allows software developers to design test cases directly within the QVTO language and verify them without moving from the transformation environment.
