The test suite is structured as a tree with the root defined as GEONW. 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.
5.2 Test groups
5.2.1 Root
The root identifies the GeoNetworking protocol given in ETSI EN 302 636-4-1 [1] and ETSI TS 103 836-4-1 [5].
5.2.2 Test group
This level contains three major areas identified as: tests of formatting and data validity, tests of protocol operation, tests
of buffer capacities.
5.2.3 Test sub-group
This level identifies the sub categories of each Group.
5.2.4 Categories
This level contains the standard ISO conformance test categories: behaviour for valid, invalid, inopportune events and
timers.

6 Test Purposes (TP)
6.1 Introduction
6.1.1 TP definition conventions
The TPs are defined by the rules shown in table 2.
Table 2: TP definition rules
TP Header
TP ID The TP ID is a unique identifier. It shall be specified according to the TP naming
conventions defined in the above clause.
Test objective Short description of test purpose objective according to the requirements from the
base standard.
Reference The reference indicates the sub-clauses of the reference standard specifications in
which the conformance requirement is expressed.
Config Id The Config Id references the GeoNetworking configuration selected for this TP.
PICS Selection Reference to the PICS statement involved for selection of the TP. Contains a Boolean
expression.
TP Behaviour
Initial conditions The initial conditions define in which initial state the IUT has to be to apply the actual
TP. In the corresponding Test Case, when the execution of the initial condition does
not succeed, it leads to the assignment of an Inconclusive verdict.
Expected behaviour (TP body) Definition of the events, which are parts of the TP objective, and the IUT are expected
to perform in order to conform to the base specification. In the corresponding Test
Case, Pass or Fail verdicts can be assigned there.
Final conditions Definition of the events that the IUT is expected to perform or shall not perform,
according to the base standard and following the correct execution of the actions in the
expected behaviour above. In the corresponding Test Case, the execution of the final
conditions is evaluated for the assignment of the final verdict.

6.1.3 Rules for the behaviour description
The description of the TP is built according to ETSI EG 202 798 [i.1].
In the TP the following wordings are used:
• "The IUT is requested to send": an upper layer requests the geonetworking layer to send a packet.
• "The IUT generates": for internal events generation, i.e. Beacon packets.
• "The IUT receives": for packets coming from the network and given by the lower layer.
• "The packet is originated by ItsNodeX": the source of the packet is ItsNodeX.
• "The packet is received from ItsNodeX": the sender of the packet is ItsNodeX.
• "The packet is addressed to ItsNodeX": the destination of the packet is ItsNodeX.
6.1.4 Sources of TP definitions
All TPs have been specified according to ETSI EN 302 636-4-1 [1] and ETSI TS 103 836-4-1 [5].
