TTCN-3
Encyclopedia
TTCN-3 is a strongly typed test scripting language
used in conformance testing
of communicating systems and a specification of test infrastructure interfaces that glue abstract test scripts with concrete communication environments. TTCN-3 has been developed by ETSI and its predecessor is TTCN-2. Despite sharing same fundamental concepts, TTCN-2 and TTCN-3 are essentially two different languages, the latter having simpler syntax and standardized adapter interfaces. TTCN-3 scripts can be combined with ASN.1 type definitions. ASN.1 is natively supported by major TTCN-3 tool vendors.
, WiMAX
, and DSRC test systems.
The Open Mobile Alliance
has recently adopted a strategy of using TTCN-3 for translating some of the test cases in an enabler test specification into an executable representation.
The AUTOSAR
project is promoting the use of TTCN-3 within the automotive industry.
Scripting language
A scripting language, script language, or extension language is a programming language that allows control of one or more applications. "Scripts" are distinct from the core code of the application, as they are usually written in a different language and are often created or at least modified by the...

Architecture
A typical TTCN-3 test system consists of:- execution core that runs test cases (TE or test execution)
- SUTSystem under testSystem under test refers to a system that is being tested for correct operation. The term is used mostly in software testing.A special case of a software system is an application which, when tested, is called an application under test....
adapter implementing TRI SA interface that is responsible for network interface code - platform adapter implementing TRI PA interface that is responsible for timers and external functions
- coding and decoding (TCI-CD interface)
- test control interface that uses TCI-TM API
