25、Requirements andGuidelines for Test Methods Specificationsand Test Method Implementations forMeasuring Conformance to POSIX StandardsSection 1: General1.1 ScopeThis International Standard is applicable to the development and use of confor-mance test method specifications for POSIX standards and may
26、be applicable toother application programming interface specifications. This International Stan-dard is intended for developers and users of test method specifications and testmethod implementations.The users of this standard include Assertion Writers: to format assertions Assertion Test Writers: to
27、 write assertion tests Test Suite or System Procurers: to interpret the results of test suitesThe purpose of this standard is to define requirements and guidelines for develop-ing assertions and related test methods for measuring conformance of an imple-mentation under test (IUT)toPOSIX standards. T
28、est method implementationsmay include Conformance Test Software (CTS), POSIX Conformance Test Pro-cedures (CTP), and audits of Conformance Documents (CD).Testing conformance of an implementation to a standard includes testing thecapabilities and behavior of the implementation with respect to the con
29、formancerequirements of the standard. Test methods are intended to provide a reasonable,practical assurance that the implementation conforms to the standard. Use of1.1 Scope 1ISO/IEC 13210: 1998 (E)IEEE Std 2003-1998 (E) TEST METHODS SPECIFICATIONS AND IMPLEMENTATIONS FORthese test methods will not

37、owing criteria: It shall use the required assertion definitions, types, syntax, and constructsspecified in this standard as applicable (see Section 3). It shall use the test result codes specified in this standard for test resultsdefined by this standard (see Section 4). It shall define any test met
38、hod specification structures and test result codesit uses in addition to those defined by this standard. It shall specify a list of conforming test result codes that indicate confor-mance to the specifications being tested (see 4.3.1).A conforming test method specification may specify other construc
39、ts not specifiedin this standard.1.3.2 Test Method Implementation Conformance CriteriaTest method implementations that conform to this standard shall include all thefollowing criteria: A test method implementation conforming to this standard shall documentthat it conforms to this standard and shall
40、document any other test methodspecifications to which it claims to conform. The test method implementation shall test each instance for an assertionthat specifies a set of instances often separated by the word or. The CTS shall be automated to the maximum extent possible. The documentation of the CT
41、S shall include the following: All information necessary to install, configure, and execute the CTS The edition of the standard being tested An overview of the CTS and the optional base standard featurestested by the CTS Deviances from the recommendations defined within this standard Known limitatio
42、ns of the CTS Release-specific changes Configuration-specific parameters Development system hardware requirements such as memory, diskspace, terminal, and printer needs Development system software requirements Hardware and software requirements necessary to execute the CTS A description of any CTS t
43、rouble-clearing procedures1.3 Conformance Criteria 3ISO/IEC 13210: 1998 (E)IEEE Std 2003-1998 (E) TEST METHODS SPECIFICATIONS AND IMPLEMENTATIONS FOR The documentation of the test method implementations shall include, ifneeded, instructions for performing the CTP and an audit of the CD. The document
44、ation of the test method implementations shall describe howto gather and interpret the results. Additional criteria may be specified in applicable standards.When no test method specification exists, test method implementations shallderive the test method specifications from the base standards and th
45、e test methodimplementation shall then meet all the criteria listed above.1.4 IUT Conformance AssessmentFigure 1-1 depicts the basic model for conformance assessment for an IUT where atest method standard is derived from an existing base standard by using thisstandard. The test method standard shall
46、 identify the test result codes that arerequired for conformance and provides the assertions from which test methodimplementations are derived. When a test method implementation is executed, itprovides intermediate test result codes that must be resolved to final test resultcodes. When the final tes
47、t result codes match the conformance test result codes,the implementation is judged to be conforming.Note: This process does not include every potential step that may be required bya certifying body, such as a conformance document audit. It addresses only therelationship between the conforming test
48、result codes identified in the testmethod standard and the final test result codes derived from the test methodimplementation.4 1 GeneralMEASURING CONFORMANCE TO POSIX STANDARDS IEEE Std 2003-19981.4 IUT Conformance Assessment5Figure 1-1 Single Base StandardISO/IEC 13210: 1998 (E)IEEE Std 2003-1998
