This part of ISO 10303 specifies the abstract test methods and requirements for conformance testing of an implementation of a language binding of the SDAI. Since the SDAI is specified independently of any programming language, the abstract test methods presented in this part are applicable to all SDAI language bindings. The abstract test methods support as well the various implementation classes as specified in ISO 10303-22. The following are within the scope of this part of ISO 10303: — abstract test methods for software systems that implement the SDAI; — the specification, in a manner that is independent of any SDAI language binding, of the methods and approaches for testing of various SDAI operations; — the specification and documentation of abstract test cases. The following are outside the scope of this part of ISO 10303: — the development of test data and/or test programs for specific language bindings; — the specification of test methods, algorithms, or programs for the conformance testing of applications that interact with SDAI implementations; — the architecture and implementation approach for a conformance test system that realizes the test methods specified in this part of ISO 10303.
