Session 32 - Software Engineering VI - Software Testing

Continuous Integration and Test from Module Level to Virtual System Level Vortragssprache Englisch

Software-in-the-Loop (SiL) is a test strategic sweet spot between Model-in-the-Loop (MiL) and Hardware-in-the-Loop (HiL) tests. We show in this paper how to use automatic C-code instrumentation to harness the superior properties of SiL technology for Module Tests even when the C-code is generated in a few, large controller functions combining the modules to be tested. Furthermore we show how to re-use module test specifications in integration and system tests by separating the test criteria from the test stimulus. We call these test criteria requirements watchers and define them as system invariants. This powerful technique, combined with efficiently handling large numbers of controller variants by annotating watchers and scripts, allows the automatic validation of hundreds of requirements in module, integration and system tests improving the software quality dramatically very early in the software development process. Last but not least, we extend the idea of continuous integration to continuous validation to leverage all of the above to reach high levels of software maturity very early in the software development process. That will also benefit later test phases – like HiL system and system integration tests – by dramatically reducing commissioning efforts.
