上面是我的启动过程，由于在微信小程序里面需要切换到不同的页面，我的处理方式是
handles = self._driver.window_handles
for window in handles:
self._driver.switch_to.window(window)
title = self._driver.title
if ':VISIBLE' in title:
logger.info(f"切换到窗口：{title}")
return True
return False
这种方式在单台设备运行的时候都没有问题，但是在多台设备同时运行的时候，运行一段时间之后再获取页面标题的时候就直接报错，报错日志如下：
