15、 5.1 Introduction For each requirement in TS 129 163 2 a TP is defined. 5.1.1 TP naming convention TPs are numbered, starting at 001, within each group. Groups are organized according to the TSS. Additional references are added to identify the actual test suite and whether it applies to the network
16、or the user (see table 5.1.1-1). Table 5.1.1-1: TP identifier naming convention scheme Identifier: TP_ = group 3 digit field representing group reference according to TSS = TP number 3 digit sequential number (001 to 999) 5.1.2 Test strategy As the base standard TS 129 235 1 and TS 129 163 2 contain
17、s no explicit requirements for testing, the TPs were generated as a result of an analysis of the base standard and the PICS specification TS 101 572-1 6. The criteria applied include the following: whether or not a test case can be built from the TP is not considered. 5.1.3 Test purpose structure Th
18、e test purpose structure is according to the test suite structure (TSS). The Reference column in each Test Purpose refers to the basic specification except stated explicitly.
