[🐛 Bug]: alerts not working properly

[bestchatgptuser]

What happened?

tried triggering an alert, then dismissing it, but Selenium never detects the alert. it's just that.

How can we reproduce the issue?

vSPDescendants.ElementAt(0).Click(); //trigger alert
var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
wait.Until(ExpectedConditions.AlertIsPresent()); //errors here. if i remove this, it will error on the next line
IAlert alert = driver.SwitchTo().Alert(); //errors here if the wait stuff is removed
alert.Dismiss(); //this code is copied straight from selenium docs, by the way

Hi, @bestchatgptuser.
Please follow the issue template, we need more information to reproduce the issue.

Either a complete code snippet and URL/HTML (if more than one file is needed, provide a GitHub repo and instructions to run the code), the specific versions used, or a more detailed description to help us understand the issue.

Note: If you cannot share your code and URL/HTML, any complete code snippet and URL/HTML that reproduces the issue is good enough.

Reply to this issue when all information is provided, thank you.

[bestchatgptuser]

it just does not get simpler than this. a popup appears, and Selenium doesn't detect it

[diemol]

Selenium can interact web app pop-ups, not OS level pop-ups. Check that, please.

Otherwise, we need a way to reproduce the issue.

Selenium can interact web app pop-ups, not OS level pop-ups. Check that, please.

If it is an OS level pop-up, I've used pyautogui for them successfully before

[bestchatgptuser]

it's a web app pop-up

[diemol]

@bestchatgptuser looking forward to see your code script so we can reproduce the issue!

This prompt you get when navigating to Google is not an alert. You can inspect it and click on the button you prefer.

I will close this issue because we never got a script to reproduce the problem.

[chukarski]

I do not see the google page, I see Unsaved Changes alert, but selenium does not see them

with options

  options.add_option(:web_socket_url, true)
  options.unhandled_prompt_behavior = :ignore

All simple dialogs encountered should be left to the user to handle.

[diemol]

That is not a web pop-up or an alert. It is an OS prompt created by the browser itself.

[chukarski]

But with gem install selenium-webdriver -v 4.26.0, it works as expected. Last lines of script are modified to

sleep 5
puts 'Waiting for Alert'
@page.visit('https://google.com/')
alert = @page.driver.browser.switch_to.alert
puts "alert -> #{alert}"
alert.accept
puts "URL #{@page.current_url}"
exit 0

And it gives

Waiting for Alert
alert -> #<Selenium::WebDriver::Alert:0x0000000128bd0870>
