Efficiency of Safety-Related Non-Functional Software Unit Test

This paper describes an investigation about the efficiency of safety-related non-functional software unit tests (NFSWUT). Well defined design, implementation and test processes are widely used in the respective industry. In order to fulfill the ISO 26262[1] requirement, additional effort is necessary to execute the NFSWUT. However, the efficiency of these tests is still not confirmed. This paper will provide an overview about an investigation of the effort-benefit ratio of the NFSWUT.
