This standard defines the test methods to be used to measure conformance to IEEE 1003.2 (Shell and Utility Application Interface for Computer Operating System Environments). To define test methods and requirements for implementation of test suites to verify conformance of implementations to the Standard Shell and Utility Application Interface for Computer Operating System Environments. New IEEE Standard - Inactive-Withdrawn. A definition of the requirements placed upon providers of a POSIX Conformance Test Suite for the POSIX.2 standard (ISO/IEC 9945-2:1993, IEEE/ANSI Std. 1003.2-1992) is provided. These requirements consist of a list of assertions defining those aspects of POSIX.2 that are to be tested and the associated test methods that are to be used in performing those tests. This standard is primarily aimed at test suite providers but it also defines to POSIX.2 implementors those aspects of the standard that will be verified by a conformance test suite.
