Example for TouchEventSequence in TestCase Qml needs some correction

Rectangle {
    width: 640; height: 480

    MultiPointTouchArea {
        id: area
        anchors.fill: parent
        property bool touched: false
        onPressed: touched = true
    }

    TestCase {
        name: "ItemTests"
       //  when: area.pressed  ---> Should be changed to windowShown
       when: windowShown
        id: test1

        function test_touch() {
            var touch = touchEvent(area);
            touch.press(0, area, 10, 10);
            touch.commit();
            verify(area.touched);
        }
    }
}
