How to access popup login form with Selenium in Python
Question: I have been trying for a while to figure out how to enter username and
password in the popup-window in this exercise:

<http://pentesteracademylab.appspot.com//lab/webapp/digest>

but I am entirely new to Selenium in Python. I found out how to click the
button, so that the login form pops up:

    
    
    from selenium import webdriver
    from selenium.webdriver.common.keys import Keys
    driver = webdriver.Firefox()
    driver.get("http://pentesteracademylab.appspot.com//lab/webapp/digest")
    driver.find_element_by_css_selector('button').click()
    

but I cannot figure out how to access that window, let alone the fields in it.
I have read about `switch_to_frame` and `switch_to_window`. For windows there
is the `window_handles` showing you active windows to switch to, but this only
returns a single element, which I believe is the main window, not the pop up.
I also tried

    
    
    alert = driver.switch_to_alert()
    

to no avail. The problem is that I do not know either which kind of object the
popup is (frame,window,alert or something else), and I cannot find any names
referring to it in the HTML code for the webpage.

Can anyone take me a step further?


Answer: Pass the authentication step by accessing the following URL:

    
    
    http://username:password@pentesteracademylab.appspot.com/lab/webapp/digest/1
