I am having issues with handling Authentication pop up in Chrome via Selenium.

from selenium import webdriver
from selenium.webdriver.common.keys import Keys 
import time

driver = webdriver.Chrome()
driver.get('URL')
time.sleep(5)
alert = driver.switch_to_alert()
alert.send_keys('Username')
alert.send_keys(Keys.TAB)
alert.send_keys('Password')

This returns an error--

"selenium.common.exceptions.NoAlertPresentException: Message: no alert open"

Alternatively, I also tried the following code:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time

driver = webdriver.Chrome()
driver.get('https://Username:Password@URL')

The second code works partially-

In Chrome the user is logged in but the page does not load. Only a blank page is displayed. Once the blank page is loaded, i passed only the URL(without user credentials) and it works fine.

In Firefox, the webpage loads perfectly.

Basically, the issue is with Chrome.

Any help is appreciated.

Thanks!

  • Try sending the username and password along with the url. – Lalindra Kawshika Dec 08 '17 at 05:27
  • I tried that. In the alternative code that I have posted in my question, I'm sending the username and password along with the url. But that doesn't load the webpage properly. – Sameem Dec 08 '17 at 05:31

  • can you share the url in which you are getting the alert or popup – Hiten Dec 08 '17 at 07:50
  • @Hiten, I cannot share the url due to confidentiality issues and even if I did, you wouldn't be able to access it unless you have an authorised VPN connection. – Sameem Dec 08 '17 at 12:37
  • Okay. Then check the url's source code. Is there any iframe ? If yes, then use that url for login and it will work. – Hiten Dec 13 '17 at 07:37
  • I believe the alert pop up is invoked by JS. I cannot see source code before logging in and I'm very sure there's no iframe. I did find a workaround though, edited the question to highlight that. – Sameem Dec 13 '17 at 13:15
  • Hey , did you find the solution. I got the same issue while adding an extension. WebdriverWait never detects the alert, when it is there. URL : https://chrome.google.com/webstore/detail/browsec-vpn-free-and-unli/omghfjlpggmjjaagoclmmobgdodcjboh?hl=en When I click add extension, the alert popped is never detected by selenium. – Ahsan Roy Feb 21 '19 at 11:43

    @AhsanRoy Nope i did not. I did find a partial solution though. It is the second part of the post. Or you can check another question tagged to this post by DebanjanB.

The second code you have tried is correct with a slight mistake.

public void loginToSystem(String username,String password, String url){
driver = webdriver.Chrome()

driver.get("https://"+username+":"+password+"@ "+URL);
}

  • Hi, Thanks for your input. The code you have suggested doesn't look very different from mine. Except that you are using variable and I was passing them directly. Kindly point out what exactly is wrong in my code. Also in your code, have you given a space character after '@'? When I tried that, the space inserted %20 after https:// eventually making the url incorrect. My issue with the second code was that the web page was not loading properly. A blank screen was displayed. As a temporary workaround I passed the url again after a wait time of 5 seconds and it worked fine. – Sameem Dec 08 '17 at 07:15

First try to wait for alert present.

wait = WebDriverWait(driver, 10)
wait.until(EC.alert_is_present())

if alert is present then only move forword to next step. And also can you please check the screenshot if alert is actually present when testcase is failing.

  • The time.sleep() provides sufficient delay until the pop up occurs. Yes, the alert is present when the script fails. – Sameem Dec 08 '17 at 12:31
  • If it is giving NoAlertPresentException, it means there is not alert present. – Maninder Jeet Singh Dec 08 '17 at 19:23
  • You can just check this approach , Inspect the elements and find their xpath or id's and try with following code element = driver.find_element_by_id('userName') element.send_keys('Username') follow the same approach for password and submit button. Hope this will work for you. – Maninder Jeet Singh Dec 08 '17 at 19:33
