ITU-T Z.165 PDF

This Recommendation provides the specification of the runtime interface for TTCN-3 test system implementations. The TTCN-3 Runtime Interface provides a standardized adaptation for timing and communication of a test system to a particular processing platform and the system under test, respectively. This Recommendation defines the interface as a set of operations independent of target language.

The interface is defined to be compatible with the TTCN-3 standards (see Z.161).

This Recommendation is technically aligned with [ETSI 201 873-5].

This Recommendation uses the CORBA Interface Definition Language (IDL) to specify the TRI completely. Clauses 6, 7 and 8 present language mappings for this abstract specification to the target languages Java, ANSI C, and C++. A summary of the IDL based interface specification is provided in Annex A.

Compliance

The requirement for a TTCN-3 test system to be TRI compliant is to adhere to the interface specification stated in this Recommendation as well as to one of the target language mappings included.

EXAMPLE – If a vendor supports Java, the TRI operation calls and implementations, which are part of the TTCN-3 executable, must comply with the IDL to Java mapping specified in this Recommendation.
