Test suite development with TTCN-3 libraries

This paper presents a methodology for test suite implementation based on Testing and test control notation (TTCN)-3 libraries which has been developed and successfully applied for the implementation of complex, standardized Internet Protocol version 6 (IPv6) conformance test suites at ETSI. It introduces the concept of a TTCN-3 library, discusses benefits and challenges, and examines the effect of some important TTCN-3 language constructs on reuse. Finally, it explains in detail a layered library design approach to test implementation in the context of a IPv6 test suite.
