The tree is of rank 3 with the first rank a Group, the second a sub-group and the third a category.

34、 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. 5.2.2 Test group This level contains three major areas identified as: tests of formatting and data validity, tests of protocol op

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 objec

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 co

38、nfiguration 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 C

39、ase, 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

40、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 corr

41、esponding Test Case, the execution of the final conditions is evaluated for the assignment of the final verdict.

In the TP the following wordings are used: “The IUT is requested to send“: an upper layer reque

45、sts 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 r

46、eceived 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. 6.1.5 Mnemonics for PICS reference The present document make
