 // Tests the Cast streaming API and its basic functionality end-to-end.  An
 // extension subtest is run to generate test content, capture that content, and
 // use the API to send it out.  At the same time, this test launches an
 // in-process Cast receiver, listening on a localhost UDP socket, to receive the
 // content and check whether it matches expectations.
 //
 // TODO(miu): Now that this test has been long-stable on Release build bots, it
 // should be enabled for the Debug build bots.  http://crbug.com/396413
