我在Python Selenium Webdriver脚本中遇到以下错误.

I am getting the following error in my Python Selenium Webdriver script.

Error Traceback (most recent call last): File "C:\Webdriver\ClearCore 501\TestCases\VariablesPage_TestCase.py", line 87, in test_add_variables variablesPage = projectnavigator.select_projectNavigator_item("Variables") # Select the Variables link from the left hand Project Navigator, it returns the Variables page object File "C:\Webdriver\ClearCore 501\Menus\project_navigator.py", line 24, in select_projectNavigator_item variables_projectnavigator_link = self.driver.find_element(*MainPageLocators.variables_project_navigator_link2).click() AttributeError: type object 'MainPageLocators' has no attribute 'variables_project_navigator_link2'

我认为这是因为该类尚未实例化.如果没有该类的实例，则无法访问成员变量. 我想我已经像这样实例化了我的班级:

I think it is because the class has not been instantiated. You cannot access a member variable without an instance of the class. I think I have instantiated my class like this:

projectnavigator = project_navigator.ProjectNavigatorPage(self.driver)

我不知道为什么会收到错误消息.

I do not know why I am getting the error.

我的代码段如下:

ProjectNavigatorPage类

class ProjectNavigatorPage

# This class defines the methods for the the ClearCore left hand project navigator # i.e. Selecting the Data Objects, Datasets, Variables, Feeds, Mappings, Data Previews etc import time from Pages.base import BasePage #from Pages.login import LoginPage from Pages.admin import AdministrationPage from Locators.locators import MainPageLocators from Pages.variables import VariablesPage class ProjectNavigatorPage(BasePage): # Select an item from the Project Navigator e.g. Data Objects tab, Datasets, Variables etc def select_projectNavigator_item(self, menu_item): if menu_item == "Data Objects": #LoginPage.clickAdministration() #self.clickAdministration(self) pass elif menu_item == "Datasets": pass elif menu_item == "Variables": variables_projectnavigator_link = self.driver.find_element(*MainPageLocators.variables_project_navigator_link2).click() return VariablesPage(self.driver) elif menu_item == "Feeds": pass elif menu_item == "Mappings": pass elif menu_item == "Data Previews": pass

推荐答案

声明变量时出现拼写错误/拼写错误

There is a spelling/typo mistake while declaring variable

variables_projet_navigator_link2 = (By.XPATH, 'html/body/div[2]/div[2]/div/div[4]/div/div[2]/div/div[3]/div/div[5]/div/div[3]/div/div[2]/div/div/div/div/div/div/div[1]/div/div[2]/div/div[1]/div[3]/div[1]/div/div[2]/div/div[2]/span')

variables_projet_navigator_link2应该是variables_project_navigator_link2
