1 Scope
The present document provides the Test Suite Structure and Test Purposes (TSS & TP) for Co-operative Awareness
Basic Service (CA) as defined in ETSI EN 302 637-2 [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 [4] and ISO/IEC 9646-2 [5]) as well as
the ETSI rules for conformance testing (ETSI ETS 300 406 [7]) are used as a basis for the test methodology.

4 Test Suite Structure (TSS)
4.1 Structure for CA tests
Table 1 shows the CA Test Suite Structure (TSS) including its sub-groups defined for conformance testing.
Table 1: TSS for CA
Root Group Sub-Group Category
CAM Message Dissemination
 Message format Valid
 Information adaptation Valid
 Generation frequency Valid and Timer
 lower layer parameters Valid
Message processing Valid

The test suite is structured as a tree with the root defined as CAM. The tree is of rank 3 with the first rank a Group, the
second a sub-group, and the third a category. The third rank is the standard ISO conformance test categories.
4.2 Test groups
4.2.1 Introduction
The test suite has a total of four levels. The first level is the root. The second level separates the root into various
functional areas. The third level is the sub-functional areas if necessary. The fourth level is the standard ISO
conformance test categories.
4.2.2 Root
The root identify the Co-operative Awareness Basic Service (CA) given in ETSI EN 302 637-2 [1].
4.2.3 Groups
This level contains two functional areas identified as:
• Message Dissemination
• Message Processing
4.2.4 Sub-Groups
This level contains four sub-functional areas identified only for the Message Dissemination group and defined as:
• Message format
• Information adaptation
• Generation frequency
• Lower-layer parameters
4.2.5 Categories
This level contains the standard ISO conformance test categories limited to the behaviour valid event 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.

5.1.3 Rules for the behaviour description
The description of the TP is built according to ETSI EG 202 798 [i.1].
The base standards are not using 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 ETSI EN 302 637-2 [1].
5.1.5 Mnemonics for PICS reference
To avoid an update of all TPs when the PICS document is changed, table 3 introduces mnemonics name and the
correspondence with the real PICS item number.
The PICS item column refers to Table/Item of ETSI TS 102 868-1 [2].
