你需要实例化WebDriverWait

wait = WebDriverWait(webdriver, 5)

你可以使用wait对象。

根据您的代码试验，我仍然不确定您的用例以及您要使用until条件的原因，until_not如下所示：

page_loaded = wait.until_not(lambda driver: driver.current_url == "http://www.demo.guru99.com/V4/manager/Managerhomepage.php")

如果您的用例是验证应用程序是否使用有效/错误的凭据将用户带到带有url的页面http://www.demo.guru99.com/V4/manager/Managerhomepage.php，则可以使用以下解决方案：

  • 要验证登录成功/失败，您可以检查包含 Managerhomepage 的新URL或包含Guru99 Bank Manager HomePage的新页面标题。因此，您可以将WebDriverWait与预期条件设置如下或如下：url_contains()title_contains()

  • 代码块：

    from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import TimeoutException
from selenium.common.exceptions import UnexpectedAlertPresentException

options = webdriver.ChromeOptions() 
options.add_argument("start-maximized")
options.add_argument('disable-infobars')
driver=webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get("http://www.demo.guru99.com/V4/")
driver.find_element_by_xpath('/html/body/form/table/tbody/tr[1]/td[2]/input').send_keys('mngr144003')
driver.find_element_by_xpath('/html/body/form/table/tbody/tr[2]/td[2]/input').send_keys('bUtymYr')
driver.find_element_by_xpath('/html/body/form/table/tbody/tr[3]/td[2]/input[1]').click()
try:
            WebDriverWait(driver, 10).until(EC.url_contains("Managerhomepage"))
        #WebDriverWait(driver, 10).until(EC.title_contains("Manager"))
        print("Login is successful. Page Title is : %s" %driver.title)
except (TimeoutException,UnexpectedAlertPresentException):
        print("Loading timeout expired")
driver.quit()

  • 控制台输出（登录成功）：

    Login is successful. Page Title is : Guru99 Bank Manager HomePage

  • 控制台输出（登录失败）：

    Loading timeout expired

代替：

try:
    page_loaded = wait.until_not(
        lambda driver: driver.current_url == "http://www.demo.guru99.com/V4/manager/Managerhomepage.php"
    )
except TimeoutException:
    driver.fail("Loading timeout expired")

和：

try:
    page_loaded = wait.until_not(EC.url_to_be("http://www.demo.guru99.com/V4/manager/Managerhomepage.php"))
except TimeoutException:
    driver.fail("Loading timeout expired")

注意：你必须做一些导入：

from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.wait import WebDriverWait

PS：你必须正确定义你的wait：

wait = WebDriverWait(webdriver, 10)
