Abstract
TTCN-3 is a language for specifying and executing test suites. The language, its operational semantics, the general structure and interfaces of a TTCN-3 test system are standardized by ETSI. Originally developed for testing telecommunication system, TTCN-3 supports real-time and scaled-time testing. In the context of the TT-MEDAL project, TTCN-3 is applied to other domains, in particularly to testing railway and automotive systems.
The systems from the railway domain have so called two-phase semantics, namely, the active phase is followed by the waiting phase. Moreover, the delays in a system are much larger then the duration of normal events. Testing such systems with real time and scaled time is inefficient.
Here we provide an approach based on simulated time that solves this problem. Our approach is implemented as a specification pattern on the level of TTCN-3 code and by adding certain features to a platform adapter of a TTCN-3 test system.
