Remarks

DataRequest events can be specific to a test case or specific to a session. When this event is raised in a test case context, intermediate data for the test case is requested. When this event is raised in a session context, intermediate data for a session is requested.

Use a method of the DataCollectionSink class that sends a Stream or a file and a userToken parameter to send intermediate data to a diagnostic data adapter.
