Abstract
TTCN-3 allows an easy and efficient description of complex distributed test behaviour in terms of sequences, alternatives, loops and parallel stimuli and responses. The test system can use any number of test components to perform test procedures in parallel. Features which are not directly supported in TTCN-3 can be included by the use of external types, data and functions. However, the access to external test behaviour is rather limited as external functions are executed as plain functions only without being performed on test components. The combination of external functions and test components allows the extension of the communication between the TTCN-3 test system and the external behaviours towards complex send/receive patterns and supports the distribution of external behaviours on remote nodes. This paper discusses the concepts of external behaviours, proposes extensions to TTCN-3 to realise them and demonstrates its application by a concrete example.
