手头有个小需求：针对一个 antd 框架的后台系统，一一点开父菜单及其子菜单（2、3、4 级），检查所有菜单对应页面是否正常。
想着，playwright 目前在自动化工具的热度升高，正好了解一下，按这个试试玩玩。

因为涉及到系统登录，所以采用 connect 方式：先浏览器启动参数增加--remote-debugging-port=9222，登录好系统，然后运行脚本。

本来这个是小脚本，但用了简单的递归：自动化这么多年都是流水帐，首次有 leetcode 照进现实的感觉，就稍微分享一下

下面是东拼西凑的脚本（说明见注释）：

currentUrl="" # 记录当前url，用于报错时记录对应url

    """

    """
    try:
        browser = await playwright.chromium.connect_over_cdp("http://localhost:%d"%debugPort)
