硒Python：这段代码是否正确？

import time 
from selenium import webdriver 
from selenium.webdriver.common.by import By 
from commonPages.LoginPage import LoginPage 
from util.InitialSetUp import InitSetup 
i = InitSetup() 
chrome_options = i.close_popup() 
driver = webdriver.Chrome(chrome_options=chrome_options) 
log = LoginPage(driver) 
log.nav_login_page() 
class Test_User_Profile: 
def test_required_fields_are_not_empty(self): 
    time.sleep(2) 
    profile_link = driver.find_element(By.CLASS_NAME, 'user-dropdown-button') 
    profile_link.click() 

    user_profile_link = driver.find_element(By.CLASS_NAME, 'user-profile-menu-item') 
    user_profile_link.click() 

    all_fields = driver.find_elements(By.TAG_NAME, 'input') 
    for field in all_fields: 
     value_of_field = field.get_attribute('value') 
     if value_of_field not in '[object Object],[object Object],[object Object]': 
      # print(value_of_field) 
      length = len(value_of_field) 
      # Assert all required fields are filled out 
      assert length > 0 

def test_required_fields_are_displayed(self): 
    all_fields_labels = driver.find_elements(By.CLASS_NAME, '_2H4nTeLi38d1fmjX5_VWUV') 
    empty = [] 
    for field_labels in all_fields_labels: 
     value_of_field = field_labels.text 
     if value_of_field not in '[object Object],[object Object],[object Object]': 
      # print(value_of_field) 
      length = len(value_of_field) 
      # Assert all required fields are displayed 
      assert length > 0 
      empty.append(value_of_field) 
      # print(empty) 
    assert empty == ['name', 'job title', 'email', 'phone', 'location'] 

# # Close modal 
# close_btn = driver.find_element(By.CLASS_NAME, 'close-profile-button') 
# close_btn.click() 

# # Close browser 
# driver.close()

上述代码有时无法运行，有时会通过。如果这是正确的，我不明白吗？硒Python：这段代码是否正确？

当它失败，给出错误信息：

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"class name","selector":"close-profile-button"} 
(Session info: chrome=59.0.3071.115)

即使定位器“关闭型材式按钮”出现在网页上。

该网页probalby还没有完全加载，所以你需要等待点击按钮。

from selenium.webdriver.support.ui import WebDriverWait 
from selenium.webdriver.support import expected_conditions as EC 
from selenium.webdriver.common.by import By 


wait = WebDriverWait(driver,60) 
wait.until(EC.visibility_of_element_located((By.CLASS_NAME, 'close-profile-button'))) 

close_btn = driver.find_element(By.CLASS_NAME, 'close-profile-button') 
close_btn.click()

这不起作用，给出一个错误消息，*等* –

它只是不正确的格式？我确实忘了一些东西，比如括号。关于更新。什么是错误信息？ – DJK

'Test_User_Profile.py:52：in Test_User_Profile element = wait.until（EC.visibility_of_element_located（By.CLASS_NAME，'close-profile-button'）） TypeError：__init __（）需要2个位置参数，但有3个被给出了' –
