Methods for Testing and Specification (MTS); The Testing and Test Control Notation version 3; Part 1: TTCN-3 Core Language

Scope

The present document defines the Core Language 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, 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 the present document.
TTCN-3 is intended to be used for the specification of test suites which are independent of test methods, layers and
protocols. In addition to the textual format defined in the present document, while GFT (ETSI ES 201 873-3 [i.2])
defines a graphical presentation format for TTCN-3. The specification of these formats is outside the scope of the
present document.
While the design of TTCN-3 has taken the eventual implementation of TTCN-3 translators and compilers into
consideration the means of realization of Executable Test Suites (ETS) from Abstract Test Suites (ATS) is outside the
scope of the present document.
