<!DOCTYPE HTML> <html> <!-- A simple test of the process priority manager. https://bugzilla.mozilla.org/show_bug.cgi?id=844323 Note: If you run this test alone (i.e. not as part of the larger mochitest suite), you may see some IPC assertions, e.g. "Can't allocate graphics resources." What appears to be happening is that we close the Firefox window before the frame we create in this tab finishes starting up. Then the frame finishes loading, and it tries to show itself. But it's too late to show a remote frame at that point, so we kill the child process. In other words, I think these errors are nothing to worry about. --> <head> <script type="application/javascript" src="/tests/SimpleTest/SimpleTest.js"></script> <script type="application/javascript" src="../browserElementTestHelpers.js"></script> <link rel="stylesheet" type="text/css" href="/tests/SimpleTest/test.css"/> </head> <body> <script type="application/javascript;version=1.7"> "use strict"; SimpleTest.waitForExplicitFinish(); browserElementTestHelpers.setEnabledPref(true); browserElementTestHelpers.addPermission(); browserElementTestHelpers.enableProcessPriorityManager(); var allCompleted = 0; var allExpected = 2; function finish() { allCompleted++; if (allCompleted === allExpected) { SimpleTest.finish(); } } function runTest() { var iframeLoaded = false; var iframe = document.createElement('iframe'); iframe.setAttribute('mozbrowser', true); iframe.src = browserElementTestHelpers.emptyPage1; iframe.addEventListener('mozbrowserloadend', finish); expectProcessCreated('FOREGROUND').then(finish); document.body.appendChild(iframe); } addEventListener('testready', runTest); </script> </body> </html>
