-// 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);
-//   // Create and register factory.
-//   TestURLFetcherFactory factory;
-//   URLFetcher::set_factory(&factory);
-//   // Do something that triggers creation of a URLFetcher.
-//   TestURLFetcher* fetcher = factory.GetFetcherByID(expected_id);
-//   DCHECK(fetcher);
-//   // Notify delegate with whatever data you want.
-//   fetcher->delegate()->OnURLFetchComplete(...);
-//   // Make sure consumer of URLFetcher does the right thing.
-//   ...
-//   // Reset factory.
-//   URLFetcher::set_factory(NULL);
-//
-// Note: if you don't know when your request objects will be created you
-// might want to use the FakeUrlFetcher and FakeUrlFetcherFactory classes
-// below.

-// The FakeUrlFetcher and FakeUrlFetcherFactory classes are similar to the
-// ones above but don't require you to know when exactly the URLFetcher objects
-// will be created.
-//
-// These classes let you set pre-baked HTTP responses for particular URLs.
-// E.g., if the user requests http://a.com/ then respond with an HTTP/500.
-//
-// We assume that the thread that is calling Start() on the URLFetcher object
-// has a message loop running.
-//
-// This class is not thread-safe.  You should not call SetFakeResponse or
-// ClearFakeResponse at the same time you call CreateURLFetcher.  However, it is
-// OK to start URLFetcher objects while setting or clearning fake responses
-// since already created URLFetcher objects will not be affected by any changes
-// made to the fake responses (once a URLFetcher object is created you cannot
-// change its fake response).
-//
-// Example usage:
-//  FakeURLFetcherFactory factory;
-//  URLFetcher::set_factory(&factory);
-//
-//  // You know that class SomeService will request url http://a.com/ and you
-//  // want to test the service class by returning an error.
-//  factory.SetFakeResponse("http://a.com/", "", false);
-//  // But if the service requests http://b.com/asdf you want to respond with
-//  // a simple html page and an HTTP/200 code.
-//  factory.SetFakeResponse("http://b.com/asdf",

-//                          true);
-//
-//  SomeService service;
-//  service.Run();  // Will eventually request these two URLs.
