A fantastic example of a partner taking advantage of the new extensibility points in Web test playback and load tests in dev10 is provided by dynaTrace. dynaTrace has developed an extension that provides enables you to drill from a particular request to the PurePath for that request. The PurePath provides a tiered performance breakdown for the request, detailing how much time the request spent at each tier of your application. Check out Andreas’s post on the integration (including some code samples!).
