Visualisation of TTCN test cases by MSCs

Practice has shown that concurrent TTCN is suitable to describe complex distributed conformance tests. Unfortunately, the entire test behaviour may be distributed over several TTCN tables and often it is difficult to keep the overall view of the test case when reading TTCN. A combined use of MSC and TTCN may improve the readability of test cases and make them more understandable. In this paper we discuss the use of MSC for the specification of test purposes and the generation of MSCs from TTCN test cases.
