Abstract

Recently, the European Telecommunications Standards Institute (ETSI) approved the third edition of the Tree and Tabular Combined Notation (TTCN-3) as a requirement to modernise and widen its application beyond pure OSI conformance testing. As part of this evolution, TTCN is embracing Message Sequence Charts (MSCs) as a natural notation for specifying and visualising test suites. This paper defines the role of MSCs during test development, and more specifically introduces an MSC profile called the Graphical Format for TTCN (GFT) that facilitates the effective specification of TTCN-3 test suites.
