Python Selenium TypeError预期3个参数（1given）

我无法解决以下问题：

下面是我的python selenium代码

import unittest
import time
import argparse, sys, os
import traceback
from selenium import webdriver
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By

class SeleniumTestPack(unittest.TestCase):

    driver = webdriver.Firefox()
    timeout = 30

    def test_all(self):

        admin_base_url = args.url
        cognito_url = "test.auth.us-west-2.amazoncognito.com"
        user_full_name = "test User"
        email = "test@test.com"
        firstName = "Selenium"
        lastName = "User"

        try:

          self.test_redirect_to_congito_login_page(admin_base_url, cognito_url)

          self.delete_geckodriver_log()

        except Exception:

          self.driver.save_screenshot('exception.png')
          self.fail("Exception: %s" % (traceback.format_exc()))

    def test_redirect_to_congito_login_page(self, admin_base_url, cognito_url):
      print "Test navigating to home page redirects to cognito login page"
      self.driver.get(admin_base_url)
      self.wait_for_element_loaded(By.ID, "div-forms")
      page_url = self.driver.current_url
      assert cognito_url in page_url

    def wait_for_element_loaded(self, id_type, id_locator):
      min_timeout = 2
      tries = 0
      retry_limit = 13
      while tries <= retry_limit:
        try:
          tries = tries + 1
          element_present = EC.presence_of_element_located((id_type, id_locator))
          WebDriverWait(self.driver, min_timeout).until(element_present)
          break
        except Exception:
          if tries <= retry_limit:
            continue
          self.fail("Exception waiting for page to load %s : %s" % (id_locator,traceback.format_exc()))

    def delete_geckodriver_log(self):
      #running function at the end of all other invocation ensures all test cases have already ran successfully
      geckodriverfile="geckodriver.log"
      if os.path.isfile(geckodriverfile):
        os.remove(geckodriverfile)
      else:
        print("Error: %s file not found" % geckodriverfile)

    @classmethod
    def tearDown(self):
      # close the browser window
      self.driver.quit()

if __name__ == '__main__':
    parser = argparse.ArgumentParser(description='test')
    parser.add_argument('--url',action='store',dest='url',default=None,help='<Required> url link',required=True)
    parser.add_argument('--username',action='store',dest='username',default=None,help='<Required> username',required=True)
    parser.add_argument('--password',action='store',dest='password',default=None,help='<Required> password',required=True)
    parser.add_argument('unittest_args', nargs='*')
    args = parser.parse_args()
    sys.argv[1:] = args.unittest_args
    unittest.main()

以下是我的输出：

ERROR: test_redirect_to_congito_login_page (__main__.SeleniumTestPack)  TypeError: test_redirect_to_congito_login_page() takes exactly 3 arguments (1 given)

我做错什么了吗？我在其他地方也做过类似的测试，很长一段时间以来效果都很好

任何帮助都将不胜感激。

这个解决方案对我来说非常陌生

<强>函数名称不应以“TestEy”>开始（否则将被视为单独的测试用例）

---

我重命名了函数名，它工作正常

您应该将

cognito\u url=“test.auth.us-west-2.amazoncognito.com”

更改为

cognito\u url=”http://test.auth.us-west-2.amazoncognito.com“

@demouser123不，没关系。这是由selenium内部处理的。请阅读我的答案！有人知道什么是“def测试（自我）”吗？我从旧的测试中获取了这行代码。好的，我知道了。“任何以

test\uuu

开头的方法都将被视为一个测试用例。”即我有一个测试用例，其中我有多个执行单个任务的小方法。
