requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 [i.5].
The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 [i.2] and ISO/IEC 9646-2 [i.3]) as well
as the ETSI rules for conformance testing (ETSI ETS 300 406 [i.6]) are used as a basis for the test methodology.

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 format Valid
Event Generation Valid
Event Update Valid and Inopportune
Event Termination Valid, Inopportune and Timer
Message Repetition Valid
Lower-layer parameters Valid
Message reception Valid and Inopportune
Keep-Alive Forwarding Valid and Timers

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 functional
area and the second rank is the standard ISO conformance test categories.
4.2 Test groups
4.2.1 Introduction
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.
4.2.2 Root
The root identifies the Decentralized Environmental Notification Basic Service (DEN) given in ETSI EN 302 637-3 [1].
4.2.3 Groups
This level contains height functional areas identified as:
• Message format.
• Event Generation.
• Event Update.
• Event Termination.
• Message Repetition.
• Lower-layer parameters.
• Message reception.
• Keep-alive Forwarding.
4.2.4 Categories
This level contains the standard ISO conformance test categories behaviour: valid events and inopportune events and
Timer.

5 Test Purposes (TP)
5.1 Introduction
5.1.1 TP definition conventions
The TP definition is built according to ETSI 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

 SSP Service Specific Permissions
= type of testing BV Behaviour: Valid event tests
 BO Behaviour: Inopportune event tests
 TI Timer tests
= sequential number 01 to 99

5.1.3 Rules for the behaviour description
The description of the TP is built according to ETSI EG 202 798 [i.1].
ETSI 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 have been specified according to ETSI 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.
The PICS item column refers to tables and items of ETSI TS 102 869-1 [2]. The 'PICS item' as defined in ETSI
TS 102 869-1 [2] shall be used to determine the test applicability.
