The customer is developing an electronic control unit for a premium German car manufacturer used to download HD map data in NDS format from an OEM cloud and supply the required map content to the automated driving unit in the vehicle via the ADASIS V3 interface. The software providing the ADASIS data must meet safety aspects according to ISO26262. The project aims to verify software testing on the integration level of components (SWE.5) for an ECU for highly automated driving. An SW environment based on Google Test is used to create and execute the test cases. The components are embedded in this environment, and the input and output interfaces are tested with test data sets.
