Your provider should get zero failures when running the Level 0 tests. If your provider supports updates and transactions, it should also get zero failures when running the Updatability and Transaction tests.
In the case of a failure, you can view and step through the ADO tests by using Microsoft® Visual Basic® 6.0. In the ADO test project, open the Project menu, click Properties, click Debugging, and then specify LTM.exe. When you press F8 to begin debugging, the Local Test Manager application will open and pass control back to Visual Basic when the tests are run.
