        理解点:
            1.实装该方法时,需要和assert_title结合
            2.为什么不把assert_title方法写在该方法里面?
                考虑到有可能其他地方会单独调到assert_title,就单独做一个assert_title方法。
            3.综上1.和2.所述,需要在该方法里面调用assert_tilte方法。

原因分析:

日志里提示在第83行调用有问题,仔细查看,原来是实例selenium_driver之后,想要通过selenium_driver 来调取类方法open_url_is_true,但是调取名字误写成了类名SeleniumDriver

对应方法:

print(SeleniumDriver.open_url_is_true("https://www.imooc.com/""程序员"))

==>

print(selenium_driver.open_url_is_true("https://www.imooc.com/""程序员"))

思考:

为什么通过类名不能调用自己类里的方法?
