Industrial Examples of Formal Specifications for Test Case Generation

While requirements engineering has received considerable attention inacademia over the past years, formalization of requirements for physicallyinfluenced systems is still a difficult task in practice. In this paper, we giveformal representations of some typical requirement classes arising in theautomotive industry. We divide these patterns into three main classes:those mostly referring to properties of continuous signals, those mostlyreferring to discrete events and those referring to similarity to a referencesignal. We discuss these patterns on concrete examples from automotiveembedded systems, where specifications are used for test case generation.
