Testing and Test Control Notation version 3: TTCN-3 language extensions: Extended TRI
|Publication Date:||1 October 2020|
This Recommendation defines the extended TTCN-3 runtime interface (TRI) package of TTCN-3. TTCN-3 can be used for the specification of all types of reactive system tests over a variety of communication ports. Typical areas of application are protocol testing (including mobile and Internet protocols), service testing (including supplementary services), module testing, testing of CORBA-based platforms, application programming interfaces (APIs), etc. TTCN-3 is not restricted to conformance testing and can be used for many other kinds of testing including interoperability, robustness, regression, system and integration testing. The specification of test suites for physical layer protocols is outside the scope of this Recommendation.
TTCN-3 packages are intended to define additional TTCN-3 concepts, which are not mandatory as concepts in the TTCN-3 core language or in its interfaces TRI and TCI, but which are optional as part of a package which is suited for dedicated applications and/or usages of TTCN-3.
This package defines a more efficient handling of software values by a version of TRI, that does not use binary encoded messages for the communication with the system under test (SUT), but uses the values as they are; meaning e.g., that software objects or serialized data can be passed directly between the SUT and the test equipment (TE).
While the design of TTCN-3 package has taken into account the consistency of a combined usage of the core language with a number of packages, the concrete usages of and guidelines for this package in combination with other packages is outside the scope of this Recommendation.
