 ### Test Plan
 
-We will e2e test this feature by deploying an OpenTelemetry Collector on the control-plane node, and configure it to export traces using the [stdout exporter](https://github.com/open-telemetry/opentelemetry-go/tree/master/exporters/stdout), which logs the spans in json format.  We can then verify that the logs contain our expected traces when making calls to the API Server.
+We will test tracing added by this feature with an integration test.  The
+integration test will verify that spans exported by the apiserver match what is
+expected from the request.
