Revised Comparison of an Automatically Generated and a Manually Specified Test Suite for the B-ISDN Protocol SSCOP

The test generation method SAMSTAG (SDL and MSC based test case generation) has successfully been applied to the B-ISDN ATM Adaption Layer protocol SSCOP (Service Specific Connection Oriented Protocol). In parallel to our work the ATM Forum developed another test suite for SSCOP. Unlike the test suite generated automatically by the SAMSTAG tool, this one was specified manually. Both test suites have been compared, but the results were only of restricted value because the test suites base on different test architectures. In order to achieve more significant comparison results the SAMSTAG tool has been adapted to the test method chosen by the ATM Forum, i.e., the remote test method, and the test suite has been re-generated. In this paper we present a revised comparison of various aspect of the two test suites.
