 // TestURLFetcher and TestURLFetcherFactory are used for testing consumers of
 // URLFetcher. TestURLFetcherFactory is a URLFetcher::Factory that creates
 // TestURLFetchers. TestURLFetcher::Start is overriden to do nothing. It is
 // expected that you'll grab the delegate from the TestURLFetcher and invoke
 // the callback method when appropriate. In this way it's easy to mock a
 // URLFetcher.
 // Typical usage:
 //   // TestURLFetcher requires a MessageLoop:
 //   MessageLoopForUI message_loop;
 //   // And io_thread to release URLRequestContextGetter in URLFetcher::Core.
-//   BrowserThread io_thread(BrowserThread::IO, &message_loop);
+//   BrowserThreadImpl io_thread(BrowserThread::IO, &message_loop);
