Automated state-based online testing real-time embedded software with RTEdge

Abstract

Verifying a real time embedded application is challenging since one has to consider timing requirements in addition to functional ones. During online state-based testing the generation and execution of test cases happen concurrently: test case generation uses information from a state-based test model in combination with observed execution behaviour. This paper describes a practical online testing algorithm that is implemented in the state-based modeling tool RTEdge. Two case studies show that our online testing algorithm produces a test suite that achieves high model coverage, thus facilitating the automated verification of real-time embedded software.
