1 Scope
The present document specifies the Abstract Test Suite (ATS) for ITS MRS service as defined in ETSI TS 103 759 [2]
in accordance with the relevant guidance given in ISO/IEC 9646-7 [i.6]. The objective of the present document is to
provide a basis for conformance tests for ITS Misbehaviour Reporting service in order to guarantee interoperability
between different manufacturers' equipment.
The ISO standards for the methodology of conformance testing (ISO/IEC 9646-1 [i.3] and ISO/IEC 9646-2 [i.4]) as
well as the ETSI rules for conformance testing (ETSI ETS 300 406 [i.7]) are used as a basis for the test methodology.

4 Contents of the ITS MRS Test Suite
The ITS MRS test suite contains:
• test implemented in TTCN-3 code;
• certificate profiles and certificate generation tool.
To execute the ITS MRS Test Suite a Test Adapter implementation and a TTCN-3 compiler are required. The reference
Test Adapter implementation can be found at https://forge.etsi.org/rep/ITS/TS.ITS.git. TTCN-3 compilers can be
acquired at http://www.ttcn-3.org.
5 Abstract Test Method
5.1 Introduction
This clause describes the ATM used to test the ITS MRS framework.
5.2 Abstract protocol tester
The abstract protocol tester used by the ITS-Mrs test suite is described in Figure 1. The Test System simulates valid and
invalid protocol behaviour and analyses the reaction of the IUT.

5.3 Test Configuration
5.3.1 Introduction
This test suite shall use test configurations as defined in ETSI TS 103 868-2 [5], i.e. the tester simulates the MA
implementing the ITS Mrs framework over HTTP protocol.
5.3.2 MRS infrastructure
5.3.2.1 Overview
Before executing tests:
• security certificates need to be generated, see clause 5.3.2.5;
• security certificates need to be installed onto the IUT, see clause 5.3.2.6; and
• some Test System settings need to be configured, see clause 5.3.2.3.
5.3.2.2 MRS certificate hierarchy
The required MRS certificate hierarchy of the test infrastructure shall be as specified in ETSI TS 102 940 [1] and ETSI
TS 103 759 [2].
The following certificates are required for the test execution:
1) The custom user-generated root certificate, referred as CERT_IUT_A_RCA, is used to sign all CA certificates
used by the Test System and by the IUT to verify the Test System certificates. For the generation procedure
see clause 5.3.2.5. The IUT shall install this CERT_IUT_A_RCA certificate and consider it as trusted. In the
case where the IUT cannot install the CERT_IUT_A_RCA, no tests can be executed.
2) The MA certificate CERT_IUT_A_MA shall be generated and installed on the IUT.
ETSI
10 ETSI TS 103 868-3 V2.1.1 (2024-05)
3) Further certificates to be installed on the IUT:
- Option 1: Certificates (CERT_TS_EA and CERT_IUT_AA) can be installed onto the IUT. See
clause 5.3.2.6 for further details on certificate installation.
If the IUT supports AT certificate selection using the UtInitialize Upper Tester command, then all
mandatory tests can be executed and PICS_CERTIFICATE_SELECTION shall be set to true.
- Option 2: The IUT can only use its own pre-installed certificates. In this case only a subset of mandatory
tests can be executed and PICS_CERTIFICATE_SELECTION shall be set to false.
In both cases it is necessary to copy these certificates to the subfolder of the location defined in
PX_CERTIFICATE_POOL_PATH. The name of the subfolder shall be provided in
PX_IUT_SEC_CONFIG_NAME.
It is not necessary to install IUT's ROOT and AA certificates onto the Test System when IUT and TS are using different
PKIs. The TS trusts any root and AA certificate from the IUT.
A set of certificates and private keys are used on the Test System side to sign various messages and other Test System
certificates. These files are generated by the generation script (see clause 5.3.2.5).
All certificates and private keys shall be stored as hexadecimal streams.
The TS selects certificate using its file name. Table 1 describes file extensions to be used to store certificates and private
keys.

Each Enrolment, Authorization or Misbehaviour Authority certificate contains:

• Geographical Validity Restriction (optional)
• Verification public key
• Encryption public key
Each Authorization Ticket certificate contains:
• Start and End time
• Assurance level as defined in ETSI TS 103 097 [3]
• Application Permissions
• Geographical Validity Restriction (optional)
