A Test-Oriented HMI Specification Model for Model-Based Testing of Automotive HMIs
GI Jahrestagung (2) 2010 (bib)

The software functionalities and complexity of todays in-car infotainment HMIs (human machine interface) have grown significantly in recent years. While model-based testing and test automation are widely-used for testing system functions, testing the HMI remains manual tasks, which are very demanding and time consuming. In our research at AUDI AG a model-based testing approach is proposed for testing both the logical behavior and the graphical interface of the automotive infotainment HMIs. As an important part of the testing approach a test-oriented HMI specification model will be designed, which describes the theoretical behavior of the HMI and contains the necessary information for automated HMI testing. HMI tests can be generated from this model. In this paper, we discuss at first the reasons why model-based testing is still not accomplished for HMI testing and introduce a technical solution from a new perspective.
