Use of TTCN-3 for the Development of SIGTRAN Tests

SIGTRAN refers to the signaling transport protocol stack standardized by IETF to build a bridge between SS7 and IP based signaling systems. Since various SIGTRAN recommendations are new and still under development there is an actual need for testing related products. The authors have investigated in the development of TTCN-3 test suites for the SIGTRAN protocols M3UA and SUA. The paper gives an insight on the development work of large industrial TTCN-3 tests. The presentation explains the selected design approach, including test configuration or module parameters. Furthermore, we describe our experiences w.r.t. the definition of (parameterized) data templates and behavior sequences. The challenges and efforts due to the test suite validation and execution will be discussed, too.
