Embedded systems are of growing importance in industry. For example, in a today's vehicle a huge number of embedded and communicating systems can be found. Exhaustive testing of such systems is a requirement, because changes after delivery and use are expensive and sometimes even impossible. In this paper we propose the use of qualitative models, which are an abstraction of quantitative physical models, for test case generation and test execution. In particular, we show how Simulink models from which control programs are automatically extracted can be tested with respect to qualitative models. Since Simulink models are heavily used in industry, the approach is of practical interest.
