21、ecification (MTS). ETSI ETSI TS 102 351 V2.1.1 (2005-08) 6 1 Scope The present document gives guidelines for the use of a common method for developing test specifications for IPv6. This method is applicable to all IPv6 categories including the core specification, mobility, security and transitioning

22、 to IPv6 from IPv4. The underlying method is based on the methodologies specified in ISO/IEC 9646-1 4 for conformance tests and TS 102 237-1 1 for interoperability tests. It provides guidance on the development and use of the following key elements of the method: - a Requirements Catalogue (RC); - a

23、 Test Suite Structure (TSS) and Test Purposes (TP); - Test Descriptions (TD) - interoperability; - a TTCN-3 library of data types and values, templates and functions; - an Abstract Test Suite (ATS) - conformance. The methodology also offers guidance on naming conventions and other style-related issu

24、es. Although the present document has been developed primarily for use in the testing of IPv6 standards, it could equally be used in other areas of protocol test specification. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the

36、 set of standards. As such, it is possible to follow the methodology specified for conformance test development in ISO/IEC 9646-1 4 without much difficulty. However, the requirements of IPv6 are distributed across a wide range of documents and an adaptation of the ISO/IEC 9646 approach to test devel

37、opment is necessary. Also, for readability, consistency and to ease reusability of TTCN-3 code it is necessary to apply some guidelines on the use of TTCN-3. It is this approach that is referred to as the “TTCN-3 Framework“. As its name implies, the framework is oriented towards the production of Ab

38、stract Test Suites (ATS) in the Testing and Test Control Notation edition 3 (TTCN-3). The TTCN-3 Framework comprises: a documentation structure: - catalogue of requirements; - Test Suite Structure (TSS); - Test Purposes (TP): square4 conformance; square4 interoperability; Abstract Test Suite (ATS):

39、- Test Cases (TC) in TTCN-3 for conformance tests; - Test Descriptions (TD) in tabulated English for interoperability tests; library of TTCN-3 building blocks: - data types and values; - templates; - general computational functions; - TP functions (see clause 7.1.3.3); a methodology linking the indi

40、vidual documentation, library and ATS elements together: - style guidelines and examples; - naming conventions; - guidelines on the use and extension of the TTCN-3 library; - a structured notation for TPs. The TTCN-3 Framework, particularly the methodology, draws heavily on the tried and tested ISO/

41、IEC 9646-1 4 but modifies it to suit the particular case of IPv6 testing. It also incorporates guidelines on interoperability testing taken from TS 102 237-1 1. 5 The IPv6 test development process The process to be followed when developing IPv6 test specifications is shown in figure 1.

The result of this analysis is the identification and classifi

44、cation of a full range of IPv6 requirements which is recorded in the Requirements Catalogue and used as the basis for both conformance and interoperability test specifications. 5.1 Conformance testing methodology Conformance test specifications should be produced following the methodology described

45、in ISO/IEC 9646-1 4. In summary, this methodology begins with the collation and categorization of the requirements to be tested into a tabular form which is normally referred to as the “Protocol Implementation Conformance Statement“ (PICS). Each PICS relates to a specific protocol standard. As the r

46、equirements of IPv6 are distributed across a large number of documents, there would be very little benefit in producing a PICS for each document. Consequently, the IPv6 requirements will be collected together and categorized in a single document, the Requirements Catalogue. For each requirement in t

47、he catalogue, one or more tests should be identified and classified into a number of groups which will provide a structure to the overall test suite (TSS). A brief Test Purpose (TP) should then be written for each identified test and this should make it clear what is to be tested but not how this sh

48、ould be done. Finally, a detailed Test Case (TC) is written for each TP. In the interests of test automation, TCs are usually combined into an Abstract Test Suite (ATS) using a specific testing language such as TTCN-3. 5.2 Interoperability testing methodology For a certification (or branding or logo

49、) scheme to be meaningful, it is necessary that interoperability testing is carried out in addition to conformance testing and that this is done in accordance with a comprehensive and structured suite of tests. In the context of the present document, it is this type of testing which is referred to as “Interoperability Testing“. The purpose of interoperability testing is to prove that the end-to-end functionality between (at least) two communicating systems is as required by the standard(s) on which those systems are based.
