Hi Marsha_R,
The purpose to run the tested application using Application Verifier and WinDbg is to trace events and exceptions of the application while TC is running the test projects.
As far as I know, TC has a plugin called DbgServices which also can be used to trace events and exception. Based on the documentation, it's very hard to compare the DbgServices with Application Verifier + WinDbg as we can't do any setup or changes to enable/disable what we desire to trace. In Application Verifier and WinDbg, we can setup the tests and event filters based on our own severity.
