`pytestqt.mouseMove` to menubar menu widget moves to wrong place

I am trying to move my mouse to the File "button" on the menubar. In my program, pytestqt.mouseMove is moving the mouse to the wrong place (it's currently clicking near the window title).

Problem:

The mouse moves to the wrong place:

Mouse Wrong Position

I need the mouse to move to the File button so I can click it. How can I achieve this?

Solution

  • The following must be taken into account:

    def test_menubar_click(app: MainApp, qtbot: QtBot) -> None:
    # Arrange
    file_menu = app.view.file_menu
    menubar = app.view.menubar
    qtbot.add_widget(menubar)
    # Act
    action_rect = menubar.actionGeometry(file_menu.menuAction())
    qtbot.wait(3000)
    qtbot.mouseMove(menubar, action_rect.center())
    qtbot.wait(3000)
