<h1>Notifications From Tests Running In An IFRAME</h1>
<p>A test is run inside an <tt>iframe</tt> with a same origin document. The
containing document should receive messages via <tt>postMessage</tt>/
<tt>onmessage</tt> as the tests progress inside the <tt>iframe</tt>. A single
passing test is expected in the summary below.
