// Bug 776129 - If a window w calls window.open, the resultant window should be
// remote iff w is remote.
//
// <iframe mozbrowser> can be default-OOP or default-in-process. But we can
// override this default by setting remote=true or remote=false on the iframe.
//
// This bug arises when we are default-in-process and a OOP iframe calls
// window.open, or when we're default-OOP and an in-process iframe calls
// window.open. In either case, if the opened iframe gets the default
// remotness, it will not match its opener's remoteness, which is bad.
//
// Since the name of the test determines the OOP-by-default pref, the "inproc"
// version of this test opens an OOP frame, and the "oop" version opens an
// in-process frame. Enjoy. :)
"use strict";
SimpleTest.waitForExplicitFinish();
browserElementTestHelpers.setEnabledPref(true);
function runTest() {
// We're going to open a remote frame if OOP off by default. If OOP is on by
// default, we're going to open an in-process frame.
var remote = !browserElementTestHelpers.getOOPByDefaultPref();
var iframe = document.createElement('iframe');
iframe.setAttribute('mozbrowser', 'true');
iframe.setAttribute('remote', remote);
// The page we load does window.open, then checks some things and reports
// back using alert(). Finally, it calls alert('finish').
//
// Bug 776129 in particular manifests itself such that the popup frame loads
// and the tests in file_browserElement_OpenMixedProcess pass, but the
// content of the frame is invisible. To catch this case, we take a
// screenshot after we load the content into the popup, and ensure that it's
// not blank.
