Would it be better to just make FrameTestHelpers do this automatically?

[lfg, 2016/09/02 17:36:38]

In this case I didn't think it was worth the effort. FrameTestHelpers already
create the widget when using the helper functions to create child frames, but in
this case we are swapping the main frame. I think this is a singular case, that
won't be reused often.

     remoteRoot->swap(localRoot);
 
     // Load a page with a child frame in the new root to make sure this doesn't
     // crash when the child frame invokes setCoreFrame.
     registerMockedHttpURLLoad("single_iframe.html");
     registerMockedHttpURLLoad("visible_iframe.html");
     FrameTestHelpers::loadFrame(localRoot, m_baseURL + "single_iframe.html");
 
     view->close();
 }
