Abstract

Automating software tests is generally desirable, and especially for the software of safety-critical real-time systems such as automotive control systems. For such systems, also conforming with the ISO 26262 standard for functional safety of road vehicles is absolutely necessary. These are embedded systems, however, which pose additional challenges with regard to test automation. In particular, the questions arise on which hardware platform the tests should be performed and by use of which workflow and tools. This is especially relevant in terms of cost, while still ensuring conformance with ISO 26262. In this paper, we present a practical approach for automated unit testing in model-based embedded software development for a safety-critical automotive application. Our approach includes both a workflow and supporting tools for performing automated unit tests. In particular, we analyze an as-is workflow and propose changes to the workflow for reducing costs and time needed for performing such tests. In addition, we present an improved tool chain for supporting the test workflow. In effect, without manually implementing each test case twice unit tests can be performed both in a simulation environment and on an open-loop test environment including the embedded platform target hardware.
