// This method generates a number of tests verifying fetching of blob URLs,
|
|
// allowing the same tests to be used both with fetch() and XMLHttpRequest.
|
|
//
|
|
// |fetch_method| is only used in test names, and should describe the
|
|
// (javascript) method being used by the other two arguments (i.e. 'fetch' or 'XHR').
|
|
//
|
|
// |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.
|
|
//
|
|
// |fetch_should_fail| similarly is a callback that is called with the Test, a URL
|
|
// 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.
