 // This tests AutoFillDownloadManager. AutoFillDownloadTestHelper implements
 // AutoFillDownloadManager::Observer and creates an instance of
 // AutoFillDownloadManager. Then it records responses to different initiated
 // requests, which are verified later. To mock network requests
 // TestURLFetcherFactory is used, which creates URLFetchers that do not
 // go over the wire, but allow calling back HTTP responses directly.
 // The responses in test are out of order and verify: successful query request,
 // successful upload request, failed upload request.
