Abstract. Test processes in the automotive industry are tool-intensive and affected by technologically heterogeneous test infrastructures. In the industrial practice a product has to pass several test levels such as Model-in-the-Loop(MIL), Software-in-the-Loop- (SIL) and Hardware-in-the-Loop- (HIL) tests. Normally, different test systems are applied for this purpose and almost each test system has its individual requirements on the test description and often requests a proprietary test description language. As a result, whole test specifications are created as an assembly from a variety of different description languages. Efforts to integrate these heterogeneous specifications, to address test exchange in a general manner and to standardize and harmonize the existing language environment are still at the beginning and not tailored towards the requirements of the automotive domain. To keep the whole development and test process efficient and manageable, the definition of an integrated a...
