1 Scope
The present document specifies the Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information
for Testing (PIXIT) proforma for the test specifications for Diameter protocol on the Cx and Dx interfaces as specified
in ETSI TS 129 228 [1] and ETSI TS 129 229 [2] in compliance with the relevant requirements and in accordance with
the relevant guidance given in ISO/IEC 9646-7 [6] and ETSI ETS 300 406 [7].
The test notation used in the ATS is TTCN-3 (see ETSI ES 201 873-1 [8]).
The following test specification and design considerations can be found in the body of the present document:
• the overall test suite structure;
• the testing architecture;
• the test methods and port definitions;
• the test configurations;
• TTCN styles and conventions;
• the partial PIXIT proforma;
• the modules containing the TTCN-3 ATS.
Annex A provides the Partial Implementation Extra Information for Testing (PIXIT) Proforma.
Annex B provides the Abstract Test Suite (ATS) part of the ATS.

3.1 Definitions
For the purposes of the present document, the terms and definitions given in ISO/IEC 9646-7 [6] and ETSI
TS 129 228 [1] apply.

4 Abstract Test Method (ATM)
4.1 Introduction
This clause describes the ATM used to test ETSI TS 129 229 [2].
NOTE: In a real operating network the different Diameter nodes would not connect directly to each other. The
connection is usually proxied through one or more Diameter Agents. In the following test architecture
figures the Diameter Agent is not explicitly depicted as it is seen as a transparent message handler for
conformance testing purposes.

4.2 Test architecture
4.2.1 Test method
The test method chosen is the remote test method. Remote test method means that the test tool (the test machine + the
executable test suite) shall behave as a CSCF when the IUT is an HSS or an SLF and shall behave as an HSS or SLF
when the IUT is a CSCF. As the exchange between the test system and the IUT is at the diameter message level, the
lower layers of the test machine shall be totally conformant with the corresponding lower layers specifications to use
the remote test method.
4.2.2 Test machine configuration
4.2.2.1 Test configurations using Cx interface
The Cx interface is located between a CSCF and the HSS.
