你的某个page是不是忘记 return driver 了，报错的截图贴一下

这个文件也截一下吧

没有找到元素，试着使用隐式等待implicitly_wait()

6

单步调试看下 self._driver 的来源即可

感谢大家的支招，来迟了，后来我又试了下，将全部变量形式改成原来的id定位写法，然后重新搞了下try…catch逻辑，用例成功调试通了，之前的报错应该是元素定位问题导致的，附上修改后的代码 :blush: :handshake:
def main(self):
“”"
1、尝试点击app首页"同意更新"按钮
2、点击失败随即进行尝试找到启动页"同意进入按钮"并点击，左滑两次并进行登录。。。。。
3、第二步如果找不到元素点击失败则意味着app已登录过一次，进行下一步的判断
4、第三步失败后进行有无缓存判断登录
5、登录后进入首页判断有无更新弹窗，有则点掉
“”"

用一对三个反单引号（英文输入法下的esc键下方） 就是代码的格式，这样贴上来的代码格式就不会乱

好的，下次我注意下，感谢
