 so we can use this in our test in some script that would run from the onload handler:

+The script passed in to runUIScript() is just a string. You can pass a string literal here, or, for longer scripts make script tag:
+{{{
+<script id="ui-script" type="text/plain">

+    testRunner.runUIScript(getUIScript(), function(result) {
+        ...
+    });
