How to add "property alias" only for testing at "QML" file.

[dmhk_4ss]

I want to add "property alias" only for testing at QML file.
Is there any way to do it ?

//sample.qml

Item {

    // I want to these properties for testing only.
    property alias innerListView: idListView
    property alias currentItem: idListView.currentItem

    ListView {
        id: idListView
        anchors.fill: parent
        clip: true
        model: weekModel
        delegate: Component
        {
            id: weekDelegate
            Item {
                id: delegateItem
                property alias text: menuText.text
                
                Text {
                    id :menuText
                    text: modelData
                }
            }
        }
    }
    ListModel {
        id: weekModel
        ListElement{day: "Sunday"}
        ListElement{day: "Monday"}
        ListElement{day: "Tuesday"}
        ListElement{day: "Wednesday"}
        ListElement{day: "Thursday"}
        ListElement{day: "Saturday"}
    }
}

Is there any way to do like this ?

//Rough idea

#ifdef TEST
     property alias innerListView: idListView
#endif

hi @dmhk_4ss and welcome

something like this could be done.

Inside your main set a property depending on specific circumstances, in this example, debug or not debug

    QQmlApplicationEngine engine;
#ifdef QT_DEBUG
    engine.rootContext()->setContextProperty("debug", true);
#else
    engine.rootContext()->setContextProperty("debug", false);
#endif

property var innerListView:  debug ? idListView : undefined //can't assign undefined to an alias -> var
