InvalidArgumentException：消息：使用&#39；的无效参数：&#39；必须是字符串

InvalidArgumentException: Message: invalid argument: #39;using#39; must be a string(InvalidArgumentException：消息：使用#39；的无效参数：#39；必须是字符串)

问题描述

我是Python的新手，正在尝试创建可重用的代码。当我试图通过传递在Login类下使用的所有参数来调用test_main.py中的类Login和函数login_user时，收到一个错误，即InvalidArgumentException：Message：Invalid ArgumentException：‘using’必须是字符串。

在pytest上运行的test_main.py文件。

locators_test是包含所有xpath的test_Locators.py文件的类

test_Locators.py

class Locators_test():

loginlink_xpath = "//a[@id='login-link']"
login_email = "xxxxx"
login_password = "xxxxx"
loginemail_id = "dnn_ctr1179_Login_txtEmail"
loginpassword_id = "dnn_ctr1179_Login_txtPassword"
clicklogin_id = "dnn_ctr1179_Login_btnLogin"

test_login.py

from Smoketest.locatorfile.test_Locators import Locators_test

class Login():

def __init__(self,driver):

    self.driver = driver

def login_user(self,driver):
    try:
        loginButton = self.driver.find_element((By.XPATH, Locators_test.loginlink_xpath))
        while loginButton.click() is True:
            break
        time.sleep(3)
        self.driver.execute_script("window.scrollBy(0,300);")

        EmailField = self.driver.find_element((By.ID, Locators_test.loginemail_id))
        EmailField.send_keys(Locators_test.login_email)

        PasswordField = self.driver.find_element((By.ID, Locators_test.loginpassword_id))
        PasswordField.send_keys(Locators_test.login_password)

        ClickLogin = self.driver.find_element((By.ID, Locators_test.clicklogin_id))
        while ClickLogin.click() is True:
            break

        time.sleep(5)

        userName = self.driver.find_element((By.XPATH, Locators_test.username_xpath))
        print("Logged in as", userName.text)



    except StaleElementReferenceException or ElementClickInterceptedException or TimeoutException as ex:
        print(ex.message)

test_main.py

    def test_setup():
        driver = webdriver.Chrome(executable_path= Locators_test.browser_path)
        driver.maximize_window()
        driver.delete_all_cookies()
        driver.get(homePage)
        driver.implicitly_wait(5)
        yield
        print("test complete")


def test_login(test_setup):

    from Smoketest.pages.test_login import Login

    lo = Login(driver)
lo.login_user(((Locators_test.loginlink_xpath,Locators_test.loginemail_id,Locators_test.login_email,Locators_test.loginpassword_id,Locators_test.login_password,Locators_test.clicklogin_id,Locators_test.username_xpath)))

缩进都很好

推荐答案

我自己修复了它，删除了该行中多余的一对括号

loginButton = self.driver.find_element((By.XPATH, Locators_test.loginlink_xpath))

正确的方法是

loginButton = self.driver.find_element(By.XPATH, Locators_test.loginlink_xpath)

PS：这适用于所有行。
