ETSI ETSI TS 186 014-3 V3.1.1 (2012-01)51 Scope The present document specifies the Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information f
18、or Testing (PIXIT) proforma based on the Test Suite Structure and Test Purposes defined in TS 186 014-2 2. The test notation used in the ATS is TTCN-3 (see ES 201 873-1 7). The following test specification- and design considerations can be found in the body of the present document: the overall test
19、suite structure; the testing architecture; the test methods and port definitions; the test configurations; the design principles, assumptions, and used interfaces to the TTCN3 tester (System Simulator); TTCN styles and conventions; the partial PIXIT proforma; the modules containing the TTCN-3 ATS. A
20、nnex A provides the Partial Implementation Extra Information for Testing (PIXIT) Proforma of the ATS. Annex B provides the Testing and Test Control Notation (TTCN-3) part of the ATS. 2 References References are either specific (identified by date of publication and/or edition number or version numbe

30、08_xxx5.2.2 Test case identifiers The test case names are built up according to the following scheme: “_“_“ ETSI ETSI TS 186 014-3 V3.1.1 (2012-01)8where: a) double quotes (“) are used to enclose literal strings; b) is the group index in Table 1 (which uniquely identifies the path of groups/subgroup
31、s); c) is a running 3-digit decimal number, starting in each subgroup path with “001“. EXAMPLE: TC_OIP_N01_001: i) the identifier has Group index “CDIV_N01“, i.e. it is in the subgroup having complete path: SupplementaryServices_CDIV/Netw/ASdivertingUser/DivProcedures; ii) the identifier is the firs
32、t test case of this group/subgroup. NOTE: This naming scheme provides a 1-1 correspondence of TP identifiers as defined in TS 186 014-2 2 and test case names. The TP identifier of TC_CDIV_N01_001 is TP CDIV_N01_001. 5.3 ATS specification framework 5.3.1 ATS Library For this ATS the TTCN-3 library mo
33、dules are basically organized as: 1) AtsCommon modules. 2) LibIms modules. 3) LibSip modules (RFC 3261 4). 4) LibCommon modules (taken from an improved version of TS 102 351 8). NOTE: Due to the common LibSip and LibIms library approach with some other parallel running projects there is necessary to
34、 create tag version of all library modules. Table 2 shows the organization of the ATS as library of modules.

43、t users of the present document may freely reproduce the PIXIT proforma in this annex so that it can be used for its intended purposes and may further publish the completed PIXIT proforma. A.1 Introduction This partial PIXIT proforma contained in the present document is provided for completion, when
44、 the related Abstract Test Suite is to be used against the Implementation Under Test (IUT). The completed partial PIXIT will normally be used in conjunction with the completed PICS, as it adds precision to the information provided by the PICS. A.2 PIXIT items According to the type of ATS defined in
45、the present document, the PIXIT are divided in PIXIT items for UE, AS and general PIXIT items that apply for all types of IUT. Each PIXIT item corresponds to a Module Parameter of the ATS. NOTE: The PIXIT definitions are part of a SIP TTCN-3 library that contains additional PIXIT definitions that ar
46、e not used in this ATS and are therefore not presented in the following tables.
