The conformance tests for OLE DB are meant to supplement a provider writer's own testing, not to replace it. They form just a part of the complete testing suite. Comprehensive testing of any OLE DB provider includes the following:
The conformance tests contribute to the first task (OLE DB interface testing) and to the last task (consumer testing, through ADO), but not the others. The conformance tests include test variations for normal usage as well as some error and boundary cases. They do not check provider-specific behavior, stress scenarios, performance, multiuser cases, application scenarios, or low-resource conditions.
