Abstract
This position paper argues that using code coverage metrics to evaluate the completeness of test cases as prescribed by e.g. ISO26262, is insufficient in a safety context. On the other hand it is impossible to execute test cases that achieve 100% completeness with respect to all possible input data combinations testing all requirements. We propose that existing requirements on code coverage shall be extended with requirements on 100% coverage of the safety requirements. As an example, the paper illustrates how this can be done for the AUTOSAR end-to-end protection library.
