InvalidArgumentException：消息：无效参数：“using”必须是字符串

Question

我对 python 很陌生，试图创建可重用的代码。当我尝试通过传递 Login 类下使用的所有参数来调用 test_main.py 中的 Login 类和函数 login_user 时，我收到错误 InvalidArgumentException: Message: invalid argument: 'using' must be a string。

在 pytest 上运行的 test_main.py 文件。

Locators_test 是 test_Locators.py 文件的类，其中我拥有所有 xpath

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"

测试登录.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)

测试主程序.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

Answer 1

我自己修复了这个问题，从行中删除了多余的一对括号

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。

Answer 2

这对我有用，

locator = (By.XPATH, Locators_test.loginlink_xpath)
self.driver.find_element(*locator).click()

解释：在 中*<arguments>，除了第一个位置参数之外的所有位置参数都将打包在一个元组中，因为它们不会被更改，确切的属性将在第二步中反映。
