1 Scope
The present document provides the Test Suite Structure and Test Purposes (TSS & TP) for Decentralized
Environmental Notification Messages (DENM) as defined in EN 302 637-3 [1] in compliance with the relevant
requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 [6].
The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 [3] and ISO/IEC 9646-2 [4]) as well as
the ETSI rules for conformance testing (ETS 300 406 [7]) are used as a basis for the test methodology.

TSS Test Suite Structure
4 Test Suite Structure (TSS)
4.1 Structure for DEN tests
Table 1 shows the DEN Test Suite Structure (TSS) including its subgroups defined for conformance testing.
Table 1: TSS for DEN
Root Group category
DEN Message transmission Valid behaviour
--- Message format Valid behaviour
--- Event Generation Valid behaviour
--- Event Update Valid behaviour
--- Event Termination Valid behaviour
--- Message Repetition Valid behaviour
Message reception Valid behaviour
Keep-alive Forwarding Valid behaviour

The test suite is structured as a tree with the root defined as DEN. The tree is of rank 2 with the first rank a Group, the
second a category. The second rank is the standard ISO conformance test categories.
4.2 Test groups
The test suite has a total of three levels. The first level is the root. The second level separates the root into various
functional areas. The third level is the standard ISO conformance test categories.
ETSI

---------------------- Page: 6 ----------------------
7 ETSI TS 102 869-2 V1.3.1 (2014-05)
4.2.1 Root
The root identify the Decentralized environmental Notification Messages (DENM) given in EN 302 637-3 [1].
4.2.2 Groups
This level contains three functional areas identified as:
• Message transmission
• Message format
• Event Generation
• Event Update
• Event Termination
• Message Repetition
• Message reception
• Keep-alive Forwarding
4.2.3 Categories
This level contains the standard ISO conformance test categories limited to the valid behaviour.
5 Test Purposes (TP)
5.1 Introduction
5.1.1 TP definition conventions
The TP definition is built according to EG 202 798 [i.1].
5.1.2 TP Identifier naming conventions
The identifier of the TP is built according to table 2.
Table 2: TP naming convention
Identifier: TP////
= root DEN
= group MSGF Message transmission - Message format
 EVGN Message transmission - Event Generation
 EVUP Message transmission - Event Update
 EVTR Message transmission - Event Termination
 EVRP Message transmission - Message Repetition
 MSRV Message reception
 KAFW Keep-alive Forwarding
= type of testing BV Valid Behaviour tests

ETSI

8 ETSI TS 102 869-2 V1.3.1 (2014-05)
EN 302 637-3 [1] does not use the finite state machine concept. As consequence, the test purposes use a generic "Initial
State" that corresponds to a state where the IUT is ready for starting the test execution. Furthermore, the IUT shall be
left in this "Initial State", when the test is completed.
Being in the "Initial State" refers to the starting point of the initial device configuration. There are no pending actions,
no instantiated buffers or variables, which could disturb the execution of a test.
5.1.4 Sources of TP definitions
All TPs are specified according to EN 302 637-3 [1].
5.1.5 Mnemonics for PICS reference
To avoid an update of all TPs when the PICS document is changed, table 3 introduce mnemonics name and the
correspondence with the real PICS item number
Table 3: Mnemonics for PICS reference
Mnemonic PICS item
PICS_KAF A.2/5 [2]
