Python3行为Web驱动程序-OOP传递驱动程序

因此，我一直在努力使我的项目更加面向对象，但我很难让驱动程序在python文件之间传递

环境.py

class DriverSetup:
    def get_driver():
        ...
        return webdriver.Firefox(executable_path=path)

def before_all(context):
        driver = DriverSetup.get_driver()
        context.actionwords = Actionwords()
        base_url = ''
        driver.get(base_url)
        AutoTools.Navigation.wait_for_page_to_load(driver)

自动工具.py

class Navigation:
    def __init__(self,driver):
        self.driver = driver

    @staticmethod
    def wait_for_page_to_load(self):
        old_page = self.driver.find_element_by_tag_name('html')

我只给了足够的地方，它得到的错误，它会击中的步骤。在调试中，Self有一个带有正确url的url，甚至还有一个窗口句柄

---

当我进入时，它返回到environment.py来运行hook exception-“WebDriver”对象没有属性“driver”

出现此错误的原因是，当调用

wait\u for\u page\u to\u load（self）

方法时，您正在访问

driver

的

属性。也就是说，当您将Firefox webdriver传递给该方法时，
self
指的是Firefox webdriver，因此它试图访问Firefox webdriver的
driver
属性，这是不正确的

你需要做的是实例化一个
Navigation
对象，这样
self
指的是所述对象，
self.driver
指的是你传递的Firefox驱动程序。从您的代码中，我希望看到如下内容：

def before_all(context):
    # These 4 lines are independent of the Navigation class
    driver = DriverSetup.get_driver()
    context.actionwords = Actionwords()
    base_url = ''
    driver.get(base_url)

    # These 2 lines are dependent on the Navigation class
    # On the right, the Navigation object is instantiated
    # On the left, the object is initialized to the navigation_driver variable
    navigation_driver = AutoTools.Navigation(driver)

    # After, you can call your method since the object's self.driver
    # was instantiated in the previous line and properly refers to the Firefox webdriver
    navigation_driver.wait_for_page_to_load()

什么是
测试自动化
行？这是命令吗？如果是，为什么有单破折号、双破折号和三破折号？
