Extended Automation Method 2.0 (EXAM) is employed at AUDI AG to perform the testing of automotive systems. The main drawback of EXAM is, that each test case must be devised and created individually. This procedure is apparently awkward and error-prone. Moreover, the development of increasingly complex functionality poses new challenges to the testing routine in industry. We employed Timed Usage Models to extend the EXAM test method. The usage model serves as the basis for the whole testing process, including test planning and test case generation. We derived automatically platform independent test cases for the execution in EXAM. Test-bench specific code was automatically generated for the test cases in EXAM, where they were executed on hardware-in-the-loop simulators (HILs). Usage models were created for functionalities from power train, comfort, and energy management. The application of usage models allowed the assessment of the test effort and the systematic generation of test cases.
