Model transformations play a vital role in Model-Driven Engineering. Due to their increasing complexity, proper means for ensuring their quality are needed. Although numerous approaches for testing of model transformations have been proposed, their focus is rather on formal verification than on execution-based testing. Additionally, existing approaches do not consider the actual transformation definition, rarely provide hints for debugging in case of an error and are specific to a certain transformation language. Therefore we propose TETRA Box as a generic framework for execution-based white-box testing of transformation languages. For this, we base on symbolic execution of model transformations. Additionally, by employing our Pattern-based Modeling Language for Model Transformations (PaMoMo), we are able to provide dedicated failure traces that are aligned to the actual transformation definition as a hint for debugging.
