Introduction
In response to EC mandate M/453 [i.6], ETSI Technical Committee (TC) ITS has standardized base and conformance
test specifications for ITS protocols. In a following step a prototype TTCN-3 conformance test system was built and
validated. The present document describes the design and validation of the prototype TTCN-3 interoperability test
system, extending the previous prototype with interoperability features.
The action described in the present document has supported the implementation of ITS standards by:
• Making available a set of standardized interoperability test specifications for V2X Applications, CAM, DENM
as well as Geonetworking functionality.
• A framework which will allow to run end-to-end interoperability test scenarios while at the same time
assessing compliance of the air interface of all ITS-S devices.
• Releasing all software as open source and thus allowing industry to build and run their own interoperability
validation framework.
The ITS Interoperability Validation Framework follows the principles of:
• Test automation.
• Support for various types of testing (conformance and interoperability testing).
• Flexible adaption to proprietary interfaces.

1 Scope
The present document provides a description of the architecture of the ITS interoperability validation framework,
including definition of the test environment, codec and test adapter. It provides, as well, all the necessary source code to
build and run the ITS interoperability validation framework.
The ITS interoperability validation framework integrates the test suites defined in ETSI TS 103 192-3 [i.4].

4 Test platform overview
4.1 Constraints and requirements
The purpose of the ITS test platform is to provide a reliable set of software and hardware equipment that can be used to
validate TTCN-3 abstract test suites (ATS) developed in ETSI.
The architecture of this test platform has been designed with respect to the following constraints:
• to be compatible with the requirements expressed in the validation handbook ( see ETSI EG 201 015 [i.2]);
• to be independent of the platform used to implement the test system (see ETSI ES 201 873-5 [i.1]);
• to be independent of the TTCN-3 tool provider;
• to be configurable and customizable;
• to provide tools and well-defined interfaces to system under test (SUT), allowing test automation;
• to be easily extensible for future ITS protocols;
• to provide generic components that can be reused in other test platforms.
In addition, great care has been taken to separate ITS specific functionalities from generic test platform tasks in order to
