The test on this line is a bit misleading now. Maybe remove it or change it to
test window.propertyIsEnumerable('DeviceOrientationEvent')?

 shouldBeTrue("'DeviceOrientationEvent' in window");
 shouldBeTrue("window.hasOwnProperty('DeviceOrientationEvent')");
 
 function hasOnDeviceOrientationProperty()
 {
     for (var property in window) {
         if (property == 'ondeviceorientation')
             return true;
     }
     return false;
 }
 
 shouldBeTrue("typeof window.ondeviceorientation == 'object'");
 shouldBeTrue("hasOnDeviceOrientationProperty()");
 shouldBeTrue("'ondeviceorientation' in window");
 shouldBeTrue("window.hasOwnProperty('ondeviceorientation')");
