 // In-Process EmbeddedWorker test helper.
 //
 // Usage: create an instance of this class for a ServiceWorkerContextCore
 // to test browser-side embedded worker code without creating a child process.
 //
 // By default this class just notifies back WorkerStarted and WorkerStopped
 // for StartWorker and StopWorker requests. The default implementation
 // also returns success for event messages (e.g. InstallEvent, FetchEvent).
 //
-// Alternatively consumers can subclass this helper and override
-// OnStartWorker(), OnStopWorker(), OnSendMessageToWorker(),
-// OnInstallEvent(), OnFetchEvent() etc to add their own
-// logic/verification code.
+// Alternatively consumers can subclass this helper and override On*()
+// methods to add their own logic/verification code.
 //
 // See embedded_worker_instance_unittest.cc for example usages.
