A Formal Framework of Hybrid Test Cases Generation Applied to Embedded Systems
In this paper, we describe a formal framework for conformance
testing of continuous and hybrid systems, using the international
standard Formal Methods in Conformance Testing FMCT. We propose
a novel test coverage measure for these systems, which is defined using
the star discrepancy notion. This coverage measure is used to quantify
the validation completeness. It is also used to guide input stimulus
generation by identifying the portions of the system behaviors that are
not adequately examined. We then propose a test generation method,
which is based on a robotic motion planning algorithm and is guided by
the coverage measure. The approach is illustrated by its application to
some embedded system benchmarks.
Keywords: Hybrid system Verification, Formal Methods in Conformance Testing and Embedded Systems design.
