This test is failing because iframe is not creating a new process as iframe is
not served from a different domain. 

[please use gerrit instead, 2016/12/06 13:24:47]

You need to do something like this:

  // Navigate the iframe cross-site.
  TestNavigationObserver load_observer(shell()->web_contents());
  GURL frame_url = embedded_test_server()->GetURL(
      "b.com", "/payment_request_iframe.html");
  EXPECT_TRUE(
      ExecuteScript(root->child_at(0)->current_frame_host(),
                    "window.location.href = '" + frame_url.spec() + "';"));
  load_observer.Wait();

Why do you need to use the HTTPS server?  If it's really needed, I think
Rouslan's suggestion should work, or alternatively you could also do
NavigateIframeToURL with that URL, or use the redirector in the HTML directly:
<iframe src="/cross-site/b.com/foo.html"> (see basic-active-in-iframe.html and
the ActiveMixedContentInIframe test for an example).  But also, why does it need
to be in chrome/?  Does the crash not repro from a content test?
