Conformance resolution tests are non-standardized, possibly system-specific, tests to fulfil test purposes for which standardized abstract test cases are not defined. They may be used to complement the standardized tests used in the conformance assessment process, in order to investigate the behaviour of an IUT with respect to particular conformance requirements.
The test architecture and test method will normally be chosen specifically for the requirements to be tested, and need not be ones that are generally useful for other requirements. They may even be ones that are regarded as being unacceptable for standardized ATSs, e.g. involving implementation-specific methods using, say, the diagnostic and debugging facilities of the specific operating system.
In particular, conformance resolution tests may include SUT-specific means of controlling the occurrence of internal events and states (e.g. internally generated reset or the "busy" state) in order to test aspects of the protocol which are untestable using a standardized ATS.
Conformance resolution tests are appropriate
Conformance resolution tests are inappropriate as a basis for judging whether or not an implementation conforms overall.
Conformance resolution tests are not standardized.
