ETSI ETSI ES 202 553 V1.2.1 (2009-06) 61 Scope The present document specifies the syntax and use of a notation for the definition
23、of Test Purposes, TPLan. This notation provides a structure and a common set of English keywords for the specification of Test Purposes. The basic notation is oriented towards testing of reactive, black-box communication systems and uses terminology derived from ISO/IEC 9646-1 3. However, facilities
24、 are also included to allow users to extend the notation with application-specific keywords of their own. The use of TPLan as the means of specifying Test Purposes is optional but, if it is used, the requirements specified in the present document shall be met. 2 References References are either spec
25、ific (identified by date of publication and/or edition number or version number) or non-specific. For a specific reference, subsequent revisions do not apply. Non-specific reference may be made only to a complete document or a part thereof and only in the following cases: - if it is accepted that it
26、 will be possible to use all future changes of the referenced document for the purposes of the referring document; - for informative references. Referenced documents which are not found to be publicly available in the expected location might be found at http:/docbox.etsi.org/Reference. NOTE: While a

38、commend that test specifications include a concise and unambiguous description of each test which focuses on its purpose. These Test Purposes, or TPs, define what is to be tested rather than how the testing is performed. The TPs are based on the requirements identified in the relevant standard (or s
39、tandards) from which the test specification is derived. The detailed coding of each Test Purpose is specified in a Test Case. Often Test Cases, or TCs, are written in a test specification language such as TTCN-3 1. The specification of Test Cases is outside the scope of the present document. General
40、ly, Test Purposes are written in prose (possibly displayed in a tabular format). There is considerable benefit to be gained by having all TPs written in a similar and consistent way. With this in mind, a simple, structured notation called TPLan has been developed for the expression of TPs. TPLan is
41、defined with a minimal set of test-oriented keywords but with the capability that permits users to define extensions to the notation. is an example of how TPLan can be extended into a specific application area; in this case, telecommunications. The benefits of using TPLan are: consistency in test pu
42、rpose descriptions - less room for misinterpretation; clear identification of the TP pre-conditions, test body, and verdict criteria; automatic syntax checking and syntax highlighting in text editors; a basis for a TP transfer format and representation in tools. 4.2 Extensibility of TPLan TPLan prov
43、ides a framework for a consistent representation (format, layout, structure and logical ordering) and a consistent use of words and patterns of words for expressing TPs. This is achieved without unnecessarily restricting the expressive power of pure prose. TPLan allows the use of keywords in combina
44、tion with free-text strings (enclosed by single quotes). Thus, the TP writer has considerable freedom of expression in the use of unstructured text between the keywords. The basic set of pre-defined TPLan keywords has been kept to a minimum. These keywords are mainly concerned with providing structu
45、re to the TPs. The intention is that this set of keywords is extended by the user for specific testing applications through the use of user-defined keywords (see clause 8) which can be checked by automatic tools for consistency and, to some extent, correctness. 4.3 The Test Suite Structure Test Purp
46、oses should be grouped in a tree-like structure. This structure is known as the Test Suite Structure, or TSS. The combination of structure and Test Purposes is known as the TSS - A to Z. Numeric: - 0 to 9. special characters: - |._- SEPARATOR := “,“; U_SCORE := “_“; qstring := “ *(“) “; ETSI ETSI ES
47、 202 553 V1.2.1 (2009-06) 27Annex B (informative): Use of the IPT Testing Framework B.1 IPT naming conventions B.1.1 IPT identifiers The IP Testing Framework 2 naming conventions provide traceability to other components of a complete test specification. For example, to the base standards, requiremen
48、ts catalogue or PICS, configuration descriptions or Test Cases. These conventions are defined in EG 202 568 2 but are repeated here for convenience. If the TPLan user wishes to follow these conventions then the syntax defined in 2 should be used. B.1.2 The Requirements Identifier The Requirements Id
49、entifier is of the form RQ_nnn_mmmm where “nnn“ is a 3-digit number and “mmmm“ is a 4-digit number. The Requirements Identifier uniquely identifies a requirement in the corresponding Requirements Catalogue, derived from the relevant base standards. For example: RQ_201_1001 In cases where a PICS (or profile PICS) is used rather than a Requirements Catalogue then the reference to the relevant PICS entry will depend on the naming conventions followed by the relevant PICS. A typical example might be: PICS_101_Table1.item3 B.1.3
