CSA Preface
Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).
This International Standard was reviewed by the CSA TCIT under the jurisdiction of the Strategic Steering Committee on Information Technology and deemed acceptable for use in Canada. (A committee membership list is available on request from the CSA Project Manager.) From time to time, ISO/IEC may publish addenda, corrigenda, etc. The CSA TCIT will review these documents for approval and publication. For a listing, refer to the CSA Information Products catalogue or CSA Info Update or contact a CSA Sales representative. This Standard has been formally approved, without modification, by the Technical Committee and has been approved as a National Standard of Canada by the Standards Council of Canada.
Scope
This standard defines the general requirements and test methods for measuring conformance to ISO/IEC 9945-1 :1990 (IEEE Std 1003.1-1990) hereinafter referred to as .POSIX.1. {3}.1 It also defines the test assertions for measuring conformance to POSIX.1{3}.
This standard is intended for use by
- Developers of POSIX.1 {3} test methods;
- Implementors of POSIX.1 {3} implementations;
- Application writers for POSIX.1 {3} conforming implementations;
- POSIX.1 {3} testing laboratories; and
- Others interested in validating the conformance of a vendor-claimed POSIX.1 {3} implementation
The purpose of this standard is to specify the test assertions and related test methods for measuring conformance of an implementation to POSIX.1 {3}.
Testing conformance of an implementation to a standard includes testing the claimed capabilities and behavior of the implementation with respect to the conformance requirements of the standard. These test methods are intended to provide a reasonable, practical assurance that the implementation conforms to the standard. Use of these test methods will not guarantee conformance of an implementation to POSIX.1 {3}; that normally would require exhaustive testing, which is impractical for both technical and economic reasons.
The technical specifications for a POSIX System Application Program Interface are defined in POSIX.1 {3}. IEEE Std 2003.1-1992 defines a means of measuring conformance to the POSIX.1 {3} technical specifications. Any question of interpretation of those technical specifications arising from the use of this standard is a question of interpretation of POSIX.1 {3}.
