- Summary:
- Software gradually takes over more and more tasks of the driver and paves the way to autonomous driving. The processes of software development and software verification are therefore crucial for manufacturers' success. Standards such as ISO 26262 highly recommend requirements-based verification. Agile development uses continuous integration testing based on test automation and evaluation. All this pushed the creation of a model-based software verification environment that provides test generation and test automatization for all kinds of signal-based tests along the V-model. This paper presents a novel core component of this environment, which is as far as to the extent possible a standard-compliant cloud-based solution to test automation at the hardware level. Based on characteristic properties of test benches, such as the wiring or the connected ECUs, hardware resources available at remote locations can be fully automated. Thus, expensive equipment only available in a limited number can be optimally exploited for testing purposes. As the availability of testing resources is a crucial aspect in software verification, a cloud-based solution can cut down the overall amount of time required for testing considerably. In close cooperation between the Ford Motor Company and Mindmotiv, a test execution engine based on Industry-4.0 message queue protocols with an integrated scheduler was developed and adapted to ASAM XiL compliant test benches for HiL-based Advanced Driver Assistance System (ADAS) testing. We present the design decisions for the software verification environment, aspects not yet addressed by standards and the necessary additions to realize a cloud-based test automation as well as the ensuing unique advantages of our approach
