6、T Z.161 (10/2015) i Recommendation ITU-T Z.161 Testing and Test Control Notation version 3: TTCN-3 core language Summary Recommendation ITU-T Z.161 defines TTCN-3 (Testing and Test Control Notation 3) intended for specification of test suites that are independent of platforms, test methods, protocol
7、 layers and protocols. TTCN-3 can be used for specification of all types of reactive system tests over a variety of communication ports. Typical areas of application are protocol testing (including mobile and Internet protocols), service testing (including supplementary services), module testing, te
8、sting of Common Object Request Broker Architecture (CORBA) based platforms and application programming interfaces (APIs). The specification of test suites for physical layer protocols is outside the scope of this Recommendation. The core language of TTCN-3 can be expressed in a variety of presentati
9、on formats. While this Recommendation defines the core language, Recommendation ITU-T Z.162 defines the tabular format for TTCN (TFT) and Recommendation ITU-T Z.163 defines the graphical format for TTCN (GFT). The specification of these formats is outside the scope of this Recommendation. The core l
10、anguage serves three purposes: a) as a generalized text-based test language; b) as a standardized interchange format of TTCN test suites between TTCN tools; c) as the semantic basis (and where relevant, the syntactical basis) for the various presentation formats. The core language may be used indepe
11、ndently of the presentation formats. However, neither the tabular format nor the graphical format can be used without the core language. Use and implementation of these presentation formats shall be done on the basis of the core language. This revision of the Recommendation contains amendments, clar
12、ifications, corrigenda and editorial corrections.

ITU-T Z.161 (10/2015) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the fiel
15、d 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 Recommendations on them with a view to standardizi
16、ng 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 approval of ITU-T Recommendations is covered
17、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 “Administration“ is used for conciseness to indicate
18、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 compliance with the Recommendation is achieved wh
19、en 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 is required of any party. INTELLECTUAL PROPER
20、TY 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 Intellectual Property Rights, whether asserted
21、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 Recommendation. However, implementers are cautioned that

24、.161 Testing and Test Control Notation version 3: TTCN-3 core language 1 Scope Recommendation ITU-T Z.161 defines the core language of TTCN-3. TTCN-3 can be used for the specification of all types of reactive system tests over a variety of communication ports. Typical areas of application are protoc
25、ol testing (including mobile and Internet protocols), service testing (including supplementary services), module testing, testing of CORBA based platforms, APIs, etc. TTCN-3 is not restricted to conformance testing and can be used for many other kinds of testing including interoperability, robustnes
26、s, regression, system and integration testing. The specification of test suites for physical layer protocols is outside the scope of this Recommendation. TTCN-3 is intended to be used for the specification of test suites which are independent of test methods, layers and protocols. Various presentati
27、on formats are defined for TTCN-3 such as a tabular presentation format and a graphical presentation format. The specification of these formats is outside the scope of this Recommendation. While the design of TTCN-3 has taken the eventual implementation of TTCN-3 translators and compilers into consi
28、deration the means of realization of Executable Test Suites (ETS) from Abstract Test Suites (ATS) is outside the scope of this Recommendation. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this
