Real-Time Test Specification with TTCN-3 (extended abstract)

Zhen Ru Dai, Jens Grabowski, Helmut Neukirchen


In this paper we propose an extension to the third edition of the Tree and Tabular Combined Notation (TTCN-3) to support real-time testing. Our approach is based on the separation of functional and real-time requirements in the test specification. Functional requirements are defined in form of stimuli and expected responses, i.e., in form of functional TTCN-3 test cases, and real-time requirements are expressed by the relationship of points in time. During test execution the points in time are collected in form of time-stamps that can be evaluated during or after the test run. We explain all extensions to TTCN-3 necessary to support the collection and evaluation of time-stamps and show the applicability of our approach by means of an example.
