This part of ISO 10303 specifies the abstract test suite to be used in the conformance testing of implementations of ISO 10303-225. The following are within the scope of this part of ISO 10303: — the specification of the test purposes associated with ISO 10303-225; — the verdict criteria to be applied during conformance testing of an implementation of ISO 10303225 using IS010303-21 or ISO 10303-22; NOTE The verdict criteria are used to ascertain whether a test purpose has been satisfactorily met by an implementation under test (IUT) within the context of a given test case. — the abstract test cases to be used as the basis for the executable test cases for conformance testing. The following are outside the scope of this part of ISO 10303: — the creation of executable test cases; — test specifications for tests other than conformance testing such as interoperability or acceptance testing; — other implementation methods.
