[🐛 Bug]: Network intercepters for authentication not working with Firefox and Chrome

[martingrossmann]

What happened?

Tried to execute the Network intercepter test canContinueWithAuthCredentials in dev.selenium.bidirectional.webdriver_bidi.NetworkCommandsTest with latest Chrome and Firefox, but got a timeout or an exception:

Firefox

Chrome
... cannot load https://the-internet.herokuapp.com/basic_auth and tests runs into a timeout.

The documentation tells it's supported since Selenium 4.18, but the example tests are disabled and do not work. What is here the latest implementation state?

What browsers and operating systems are you seeing the problem on?

• Chrome 122 with latest chromedriver,
• Firefox 123 with geckodriver 0.34.0
• Windows 10

I have an update: With Selenium 4.19.1 the Network examples are working with Firefox 124, but not with Chrome.

Unfortunately, with Chrome 124 I still get a timeout. Does anybody know whats wrong with Chrome?

I remember I wanted to check this but got distracted by something else.

If you check https://github.com/SeleniumHQ/selenium/blob/aaa7e791a4b6be6314250966a4538cd594576254/java/test/org/openqa/selenium/bidi/network/NetworkCommandsTest.java#L45, they are only executed with Firefox. Chrome still needs to implement this.

We have the code examples disabled for that reason.

Is that right, @pujagani?

[pujagani]

Yes! That's correct. Chrome's stable release does not support it. Looks like the latest Canary has the support https://wpt.fyi/results/webdriver/tests/bidi/network?label=master&label=experimental&aligned&view=subtest.

[martingrossmann]

Thanks for your input, makes something clearer. :-)

I will close this as the question has been answered.
