Issue closing an Modal Alert (popup)

[leviathan54]

Following suggestion from @Larz60+ I have simplified the code so username/password is hardcoded and no spreadsheet is referenced.

It looks to me like the accept alert is actually working with this script BUT something is happening that preventing me recording the test result. so for example if i successfully login then it will print "test is passed" but if i don't successfully login it does not print "test failed". Instead I get this error message

Traceback (most recent call last):
  File "C:/Users/David/PycharmProjects/POM/Login2.py", line 21, in <module>
    if driver.title == "Guru99 Bank Manager HomePage":
  File "C:\Python37\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 342, in title
    resp = self.execute(Command.GET_TITLE)
  File "C:\Python37\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "C:\Python37\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 241, in check_response
    raise exception_class(message, screen, stacktrace, alert_text)
selenium.common.exceptions.UnexpectedAlertPresentException: Alert Text: None
Message: Dismissed user prompt dialog: User or Password is not valid

Here is my simplified script. You can cut and paste this script to test with

from selenium import webdriver
import unittest
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC


profile_path = 'C:/FireFoxProfile'
profile = webdriver.FirefoxProfile(profile_path)
driver = webdriver.Firefox(firefox_profile=profile_path)
driver.implicitly_wait(2)
driver.get('http://www.demo.guru99.com/V4/')
driver.maximize_window()

username = "mngr189426" #correct password is "mngr189426"
password = "fail" #correct password is "hapEnyn"

driver.find_element_by_name("uid").send_keys(username)
driver.find_element_by_name("password").send_keys(password)
driver.find_element_by_name("btnLogin").click()
#if login is successful then check website is on right page and pass/fail test
if driver.title == "Guru99 Bank Manager HomePage":
    print("test is passed")
else:
    print("test failed")
    # return to homepage and insert password/username for next row in spreadsheet
    WebDriverWait(driver, 20).until(EC.alert_is_present).accept

    unittest.main(verbosity=2)
