IIUC cross origin resources report timing values of zero.

[Charlie Harrison, 2016/04/05 21:56:30]

Does this count as cross origin? I'm seeing valid startTimes locally.

 document.write('<scr' + 'ipt src="' + src + '"></scr' + 'ipt>');
 </script>
 <script>
 window.addEventListener("load", t.step_func(function() {
-    var resourceTiming = window.performance.getEntriesByType('resource')[2];
-    assert_less_than(resourceTiming.startTime, boundedStart);
-    t.done();
+  window.performance.getEntriesByType('resource').forEach(function(r) {
+    if (r.name.indexOf('dummy.js') != -1) {
+      assert_less_than(r.startTime, boundedStart);

[Bryan McQuade, 2016/04/05 20:34:09]

given the above, we should probably assert that r.startTime > 0 as well (and in
the other tests as well)

[Charlie Harrison, 2016/04/05 21:56:30]

Done.

+      t.done();
+    }
+  });
 }));
