[🐛 Bug]: Unable to run a test because driver cannot connect to DevTools

[pirquessa]

What happened?

I'm having an issue when trying to run my enterprise end to end tests. It was working well and it is no more the case, I can't understand why. The same test work for my collegues.

I've created a small code to reproduce quickly the issue that is not link to any professional data.

I'm currently using Unbuntu 22.04.4 LTS, Google Chrome 126.0.6478.126 and the matching chrome driver downloaded by Selenium.

ls -al ~/.cache/selenium/chromedriver/linux64
total 12
drwxrwxr-x 3 pirquessa pirquessa 4096 juil. 10 14:24 .
drwxrwxr-x 3 pirquessa pirquessa 4096 juil. 10 14:24 ..
drwxrwxr-x 2 pirquessa pirquessa 4096 juil. 10 14:24 126.0.6478.126

When I run ruby ./driver.rb, I get an error linked to connection with DevTools:

#0 0x637232177c7a <unknown>: disconnected: Unable to receive message from renderer (Selenium::WebDriver::Error::WebDriverError)
  (failed to check if window was closed: disconnected: not connected to DevTools)

How can we reproduce the issue?

Here is my `driver.rb` to reproduce the issue:


require 'selenium-webdriver'

driver = Selenium::WebDriver.for(:chrome)
driver.get 'https://selenium.dev'
driver.quit

### Relevant log output

Where are you executing this code? Do you have a screen or window manager?

[pirquessa]

Where ? On my Ubuntu laptop.
Do you have a screen or window manager? I don't understand what you're talking about :(

[diemol]

There are several issues open related to that error. A couple of them were due to an issue Selenium fixed a while ago, and the rest are issues in Chrome. Please check them, I believe yours should be there.

https://github.com/SeleniumHQ/selenium/issues?q=is%3Aissue+not+connected+to+DevTools+

[pirquessa]

I've seen the list, I didn't find any solution for me :(

[diemol]

Can you share the logs, maybe there is something there. Otherwise, you'd need to report it to the Chrome folks.

[github-actions]

We need more information about this issue in order to troubleshoot.

Please turn on logging and re-run your code. Information on how to adjust logs for your language can be found in our
Troubleshooting documentation.

So I'me modified my script:

require 'selenium-webdriver'

logger = Selenium::WebDriver.logger
logger.level = :debug

driver = Selenium::WebDriver.for(:chrome)
driver.get 'https://selenium.dev'
driver.quit

I get

Same problem, selenium_chrome stopped working from one day to another without any known change (no library updates, no OS updates).

Stack traces vary a bit, but look similar. Here are two examples:

There is little we can do about this issue at the Selenium project because it is entirely related to the Chrome browser, which cannot start correctly in some situations. Please report this to the Chrome folks and provide them with a way to reproduce the issue.

Hi, @pirquessa.
This issue has been determined to require fixes in ChromeDriver.

You can see if the feature is passing in the Web Platform Tests.

If it is something new, please create an issue with the ChromeDriver team.
Feel free to comment the issues that you raise back in this issue. Thank you.

Okay, I found the solution. If you launch it in headful you can see it's asking the user to select the default search engine, blocking the test from executing. This behaviour can be disabled with the option --disable-search-engine-choice-screen

Here's a full config that works for me:

Capybara.register_driver :selenium_chrome_headless_tmp_fix do |app|
  options = Selenium::WebDriver::Chrome::Options.new
  options.add_argument('--headless')
  options.add_argument('--window-size=1280,800')
  options.add_argument('--disable-search-engine-choice-screen')

  Capybara::Selenium::Driver.new(
    app,
    browser: :chrome,
    options: options
  )
end

I'd suggest to make this the default in the selenium_chrome_headless driver

Thx for the tip @mpkhr. But this fix has already been applied in my company without any change on my situation :'(
