Abstract

Testing is a process detecting errors in the design of software and hardware. Tests can normally not prove the correctness of programs or hardware, since they usually form only a small subset of all possible inputs or situations. Therefore, test cases should be chosen carefully and should cover the set or space of possible inputs or situations as broadly as possible. Thus, test coverage is one of the crucial question in testing. In this paper, we focus on conformance test for low level communication protocols like FlexRay or LIN as they are found very often in cars. These conformance tests are usually defined by choosing specific values for a larger number of variables. In this paper, we propose a method that can visualise the test cases in comparison to all possible situation and provides important information about the test coverage.
