// |options.url|: the URL to fetch
// |options.fetch_option|: the options passed to |fetch_method|
// |options.fetch_method|: the method used to fetch. Useful for testing an
// iframe's fetch() vs. this page's fetch().
// |options.expected_type|: The value of response.type
// |options.expected_redirected|: The value of response.redirected
// |options.expected_intercepted_urls|: The list of intercepted request URLs.
