Development environments that support Model-Driven Development often focus on model-level functional testing, enabling verification of design models against their specifications. However, developers of safety-critical software systems are also required to show that tests cover the structure of the implementation. Unfortunately, the implementation structure can diverge from the model depending on choices such as the model compiler or target language. Therefore, structural coverage at the model level may not guarantee coverage of the implementation.
