Towards a GUI Test Model Using State Charts and Programming Code

Modern human machine interfaces provide a sophisticated structure and logic to ease their use. As they are the only mean to control the system behind, extensive testing and highest quality is required in the automotive domain. A common testing approach in literature is to derive the necessary test cases from a formal model. However, redundancy and data dependency still hinder manual modeling in the industrial context. In this paper, we present preliminary work to address these obstacles. As a first step, we combined depictive state charts with reusable programming code. We modeled parts of the graphical user interface of a state-of-the-art infotainment system and successfully generated a test suite that covers our testing goal to reach each button at least once.
