The DevTest-specific Test Event tracer is a "method" tracer. A method tracer means that it contains code that is inserted immediately before and after a specific method call. The Test Event tracer is designed to instrument the method that is the constructor of the BaseCoordinator class. After the constructor completes, the tracer creates a Test Event Listener and registers this listener with the coordinator. The listener then receives each TestEvent object of the types that were shown previously. The listener extracts relevant information from these TestEvent objects and sends that information to the Introscope Enterprise Manager in the form of Introscope metric values.
The DevTest Workstation screen shot that follows shows the TestEvents generated by one run of a test case named "broken," which contains an error. To understand which of the Introscope metrics are created, look up each value in the Event column, in Metrics Reported by Tracers.
