Specialist Task Force 409: Conformance tests for TTCN-3 tools
Who we are:
Team Leader: Zeiss, Benjamin, Georg-August University
Team Members: Stanca-Kaposta, Bogdan, Testing Technologies,
Kovacs, Andras, Broadbit Slovakia,
What we do:
The purpose of this work is to start the implementation of a TTCN-3 tool conformance test specification for TTCN-3 tools, i.e., we
specify ICS, test purposes and TTCN-3 tests for those aspects of the TTCN-3 core language standard, which are considered to
be the most critical by the TTCN-3 community.

Terms of Reference
Why we do it:
Over the last 10 years TTCN-3 has become a significantly important testing
technology with very high deployment at various ETSI member companies as well as
other organizations internationally. With its uptake by 3GPP, OMA and the
AUTOSAR (a consortium of car makers and OEM suppliers), its role in
standardization is further growing. 3GPP is using TTCN-3 as the test
specification language for IMS call control testing from Rel. 8 onward and. TC
TISPAN is using TTCN-3 for NGN supplementary service and interworking test
specification. TC INT is using TTCN-3 for automating IMS core network
interoperability testing. TC ITS is using TTCN-3 to specify all its test suites
under the EC mandate M/453. Since 2004, ETSI organizes an annual, international
user conference where it collects feedback from the wide TTCN-3 user community.
The first ETSI TTCN-3 tools Plugtest has been organized in 2009.
A significant number of TTCN-3 compilers are available
on the market (at least 7 commercial tools and 2 internal tools
of industrial ETSI members) that also indicate the high interest
and use of the language. The TTCN-3 standards which provide the
foundation for this testing technology, are however quite
complex and encompass multiple hundreds of pages. Part 1 of the
TTCN-3 series, the TTCN-3 core language, alone is estimated to
contain on the order of 5,000 requirements. Although there has
been to this day no evidence of incorrect tool implementations,
the TTCN-3 community has been repeatedly requesting over the
past 10 years for some kind of assurance that tools comply to
the TTCN-3 standards, i.e., a conformance test suite. This STF
is intended to create a first TTCN-3 conformance test suite for
the purpose of ensuring that TTCN-3 tools actually comply to
ETSI TTCN-3 standards.
How we do it:
The total manpower of this STF is 60 working days
with one big session from the beginning of October at ETSI and coordinated work
outside until the end of December. The basis for the STF 409 work is a proforma
for TTCN-3 tool conformance test specification that has been created previously
in TC MTS by STF 380 and 393. Decisions are coordinated with both MTS and
voluntary review contributors from ISPRAS, the University of Göttingen, Metodos
y Technologia, and Elvior. As a result, the STF work is an effort in which many
TTCN-3 tool vendors either actively participate or contribute. The coordination
is performed by use of the mailing list
The STF will provide the following
draft ETSI deliverables, to be approved by correspondence during 1Q2011:
- DTS/MTS-00132-1T3 TTCN-3 Conformance Test Suite ; Part 1: ICS
- DTS/MTS-00132-2T3 Conf_TPs
TTCN-3 Conformance Test Suite ; Part 2: TSS&TPs
- DTS/MTS-00132-3T3 Conf_ATS
TTCN-3 Conformance Test Suite ; Part 3: ATS & IXIT
the work will be the result of two main session that will take place on the
- Session at
ETSI from October 4, 2010 until October 15, 2010 at ETSI.
session outside from November 8, 2010 until November 19, 2010.
By December 3, 2010, most of the STF work shall be finished according to the
preliminary plan, i.e., a stable draft is planned to exist by December.
