1556026 - User prompt of type promptUserAndPass is not supported when entering text in an alert()

Status: RESOLVED DUPLICATE of bug 1556307

(Testing :: geckodriver, defect)

Description

[elinnore]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:67.0) Gecko/20100101 Firefox/67.0

Steps to reproduce:

I am using python selenium to go through an authentication process.
The code is opening a page that displays an alert.
I am passing some text to the alert and I obtain the error mentioned in the next section.
This issue occurred after Firefox was updated to 67.0.
Code works fine using any version < 67.0 (55.0+).
OS: MacOS 10.14.5
Issue is present in on multiple OS and was reported already to Selenium:
https://github.com/SeleniumHQ/selenium/issues/7239

This might not be an issue related to Firefox as everything works fine in GUI. However, what has been changed in Firefox 67.0 with respect to alerts?

python 3.7.0
selenium 3.141.0
geckodriver: v0.24.0 (https://github.com/mozilla/geckodriver/releases)

Code:

import os
import sys
import pdb
from selenium.webdriver import Firefox

file_path = os.path.realpath(__file__)
head, tail = (os.path.split(file_path))
sys.path.append(head)
os.environ['PATH'] += os.pathsep + head

base_url = 'https://www.httpwatch.com/httpgallery/authentication/'
browser = Firefox()
browser.get(base_url)
browser.find_element_by_id('displayImage').click()
dialog = browser.switch_to.alert
dialog.send_keys('myuser' + u'\ue004' + 'mypass')

Actual results:

Error

Please see the developer changes for Marionette (Webdriver) in Firefox 67:

https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Releases/67#WebDriver_conformance_(Marionette)

Generally, using HTTPAuth dialogs isn't supported yet by any driver. As such there is a need for a new API end-point which will be defined/setup via https://github.com/w3c/webdriver/issues/385. Sadly we cannot add this before the spec has been written.

So that behavior is expected for the moment, and you will have to wait for bug 1556307 being fixed.
