| // |fetch_should_succeed| is a callback that is called with the Test and a URL. |
| // Fetching the URL is expected to succeed. The callback should return a promise |
| // resolved with whatever contents were fetched. |

| // to fetch, and optionally a method to use to do the fetch. If no method is |
| // specified the callback should use the 'GET' method. Fetching of these URLs is |
| // expected to fail, and the callback should return a promise that resolves iff |
| // fetching did indeed fail. |
