9、ecommendation ITU-T X.783 provides guidelines for implementation conformance statement (ICS) proformas for web services-based interface systems. It provides an overview and constructions for the web service description language (WSDL), and provides several proformas (tables) for each WSDL component
10、to be used in interfaces. Instructions on how to complete the columns in the conformance tables are also provided. Examples of web services interface ICSs are provided in appendices.

12、nited Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recomm
13、endations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The a
14、pproval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administ
15、ration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compl
16、iance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation i
17、s required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Int
18、ellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendatio

ITU-T X.783 (07/2014) 3 6 Basis of conformance test methodology for WSDL-based management system interface 6.1 Overview Conformance relates an implementation to a standard. It states in which way systems, implemented with respe
38、ct to a standard, can vary without errors occurring in their cooperation. If an implementation fulfils these requirements, it is conformant to the standard. The check of the statements is the conformance test. The starting point is the definition of conformance requirements in implementation indepen
39、dent interface specifications on the basis of identification of reference points (RPs). A management interface specification should define conformance RPs at which an implementation must be tested to check if it fulfils a set of conformance criteria. During the test, a number of stimuli and events a
40、re observed and evaluated at these conformance RPs. Management interface specifications should include conformance statements which identify conformance RPs at every interface of the specified implementations. Because, in general, the information flow between two system components is realized throug
41、h several RPs, the conformance test has to take the following into consideration: a) the test of information flow at each RP; b) the test of consistency between the combinations. Thus, a coordinated test, at all identified RPs is necessary. 6.2 Methodology of conformance test for web service-based i
42、nterfaces There are static and dynamic conformance test requirements: a) Static conformance test requirements state the functionality that is minimally necessary for conformance testing. The basis of the static conformance test is an implementation conformance statement (ICS) proforma where the func
43、tional limitations and possibilities of the standard are defined. It is a document in the form of a questionnaire that has to be completed by the implementer. b) Dynamic conformance test requirements specify the potential behaviours of an implementation visible at the identified RPs. The dynamic con
44、formance test contains the realization of test cases in a testing system. Test cases include concrete test cases and abstract test cases. The concrete test cases are derived from abstract test cases that are given or defined by the standard. A basic precondition for the derivation of the test cases
45、is the definition of test purposes by the standard. Before starting the test in a test laboratory, the steps below must be followed: a) The implementer has to complete the given ICS proforma. Information which makes the ICS proforma statements more precise or concerns the test realization is include
46、d in the implementation extra information for testing (IXIT). b) The so-called real (concrete) test cases should be derived from the abstract test cases of the standard, or they can be derived from the test purposes directly, where generic aspects (e.g. types) are realized depending on the individua

ITU-T X.783 (07/2014) Figure 1 Testing process of WSDL-based interfaces 6.3 Relationship between this Recommendation and other Recommendations a) Relationship with ITU-T X.296 ITU-T X.296 provides the common basic for ICS proformas. This R
48、ecommendation uses the concepts from ITU-T X.296. b) Relationship with b-ITU-T X.781 b-ITU-T X.781 provides the guidelines for ICS of common object request broker architecture (CORBA)-based systems. The conformance testing of this Recommendation use b-ITU-T X.781 as an example, and use some tables f
49、rom b-ITU-T X.781 and make corresponding changes based on web services technology accordingly. c) Relationship with b-ITU-T M.3031 b-ITU-T M.3031 mainly deals with the telecommunications markup language (tML)-based ICS proforma definition, but there are no ICS proformas to verify interaction, only some to verify conformance of tML-based data types. This Recommendation provides the ICS proformas for both interface interactions as well as data t
