This exercise will present a popup dialogue asking for your credential (which is admin, admin as shown in the exercise). This popup is not an alert nor an iframe, the only way is to include the username and password with the address to get through it with selenium.
I have added a line if the driver is not found, then use webdriver-manager to install it. This will how it looks like if geckodriver is not found.
The code for as follows:
from selenium import webdriver
from selenium.common.exceptions import UnexpectedAlertPresentException, WebDriverException
import os
def find_file(base="C:\\", name=None):
"""
Find file and return the first match found.
:param base: Base path to search
:param name: filename to search
:return: absolute path of the file.
"""
for root, dirs, filename in os.walk(base):
if name in filename:
return os.path.join(root, name)
try:
has_driver = find_file(name="geckodriver.exe")
if has_driver:
# if driver is found.
driver = webdriver.Firefox(executable_path=has_driver)
else:
# Thank you Sergey Pirogov for creating webdriver manager module.
from webdriver_manager.firefox import GeckoDriverManager
driver = webdriver.Firefox(executable_path=GeckoDriverManager().install())
try:
# No exception is good news.
# if auth has failed UnexpectedAlertPresentException will appear.
driver.get("https://admin:admin@the-internet.herokuapp.com/basic_auth")
if "Congratulations! You must have the proper credentials." in driver.page_source:
print("Authentication successful!")
except UnexpectedAlertPresentException as e:
# Only use stderr if exception is caught.
from sys import stderr
stderr.write(str(e))
finally:
# close the driver regardless of whatever.
driver.close()
except WebDriverException as e:
from sys import stderr
stderr.write(str(e))
