使用Qtbot模拟鼠标在菜单栏和工具栏中的点击

from PyQt5.QtWidgets import QApplication, QMainWindow, QMenu, QAction, QToolBar

from pytestqt import qtbot

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        fileMenu = menubar.addMenu('File')

        # 添加菜单项
        openAction = QAction('Open', self)
        fileMenu.addAction(openAction)

        # 创建工具栏
        toolbar = QToolBar(self)
        self.addToolBar(toolbar)

        # 添加工具栏按钮
        toolbar.addAction(openAction)

def test_menu_toolbar_click(qtbot):
    app = QApplication(sys.argv)
    main_window = MainWindow()
    main_window.show()

    # 模拟点击菜单栏中的"Open"
    menu_open_action = main_window.menuBar().findChild(QAction, 'Open')
    qtbot.mouseClick(menu_open_action, Qt.LeftButton)

    # 模拟点击工具栏中的"Open"
    toolbar_open_action = main_window.findChild(QAction, 'Open')
    qtbot.mouseClick(toolbar_open_action, Qt.LeftButton)

    sys.exit(app.exec_())
