wrap function(items) in a chrome.test.callbackPass - and the idiomatic way to do
that is for "var pass = chrome.test.callbackPass" at the top, then use
"pass(function(items) {.." here.

Done.

+      var extensionoptions = document.createElement('extensionoptions');
+      extensionoptions.addEventListener('createfailed', function() {
+        try {
+          chrome.runtime.sendMessage(items['embeddedId'],
+                                     'checking for options page',
+                                     function(response) {
+            chrome.test.assertFalse(response.hasOptionsPage);
+            done();
+          });
+        } finally {
