尝试使用 POM 运行此代码但出现错误。硒版本= 4.8.3

测试用例文件：

\`import time

from selenium import webdriver
from Functions import definedFunctions
from locators import Locators
from data import form

class New():

    def __init__(self):
        self.driver = None
    
    def setup(self):

        driver.maximize_window()
        driver.get("https://demoqa.com/")
        
    def Text_box(self):
        elm = definedFunctions(self.driver)
        lc = Locators
        data = form

Answer 1

检查您的“驱动程序”参数。目前错误指出， “NoneType”对象没有属性“find_element”。

_element_if_visible(driver.find_element(*locator)) ^^^^^^^^^^^^^^^^^^^ AttributeError：'NoneType'对象没有属性'find_element'

查看这几行代码，我们看到该对象是“driver”。

driver.find_element()

因此没有提供有效的驱动程序。
