IntegTTCN, a TTCN language extension for protocol integrated testing

This paper proposes an extension to TTCN to meet the requirements of protocol integrated testing. Compared with TTCN, the extension of IntegTTCN consists of test data and test behaviour. To test data, IntegTTCN can describe dynamic data and statistical data in addition to static data. To test behaviour, IntegTTCN extends test components, adds concurrent operation statements, and reinforces timer operations. After specifying the syntax of IntegTTCN, its operational semantics is defined in terms of an input-output transition system. Finally, IntegTTCN is compared with other test suite notations.
