 //
 // Usage: create an instance of this class to test browser-side embedded worker
 // code without creating a child process.  This class will create a
 // ServiceWorkerContextWrapper and ServiceWorkerContextCore for you.
 //
 // 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 On*()
 // methods to add their own logic/verification code.
 //
 // See embedded_worker_instance_unittest.cc for example usages.
