Not sure if the way the storage tests are run, inside a class, is messing up some fixture order or something like that. 2131505 1 lmoura 2025-07-20 16:44:21 -0700 Just confirmed that this is not a storage-specific thing. In the `imported/selenium/py/test/selenium/webdriver/common/bidi_browsing_context_tests.py::test_activate_browsing_context[wpewebkit]` test we get the same issue: ERROR WebDriverTests/imported/selenium/py/test/selenium/webdriver/common/bidi_browsing_context_tests.py::test_activate_browsing_context[wpewebkit] - urllib3.exceptions.MaxRetryError: HTTPConnectionPool(host='localhost', port=43417): Max retries exceeded with url: /session/2dbd1aad-adca-4c11-9428-63076266640a (Caused by NewConnectionError('<urllib3.connection.HTTPConnection o...

If all tests are passing, no problem. - Interestingly, `xfail` reports the failure, but the teardown error doesn't seem to happen - The same selenium test suite works fine when invoked from bazel or manual pytest (from Selenium repository) (Also update the title as it's not BiDi-related) 2138971 4 lmoura 2025-08-26 20:38:16 -0700 So, the issue is related to selenium's pytest fixtures trying to send the quit command after the original driver had already exited. I'll submit a patch upstream and likely do another import in this issue, as we already have selenium 4.35 out. 2142870 5 lmoura 2025-09-14 20:11:38 -0700 Pull request: https://github.com/WebKit/WebKit/pull/50727 2146065 6 ews-feeder 2025-09-25 21:50:09 -0700 Committed 300552@main (840ba04a5102): <https://commits.webkit.org/300552@main> Reviewed commits have been landed.
