Created attachment 315982 [details] Patch Note that this fixes testShouldTimeoutOnPageLoadTakingTooLong but not testClickShouldTimeout. The wait after a click is racy. Right after the click happens in the UI process, the page load hasn't started yet, so we can't start the wait there like we do with navigation commands, and when the command returns and thr web driver asks the browser to wait, the load has already happened. I don't think it's possible to solve that, and I don't think it's worth it either, since the test case is actually testing a very weird case (very small timeout and very fast load).

Not really, only the two tests I mentioned before set a page load timeout: $ git grep set_page_load_timeout page_load_timeout_tests.py: driver.set_page_load_timeout(0.01) page_load_timeout_tests.py: driver.set_page_load_timeout(0.01) And the default timeout is so long (300 seconds) that it doesn't affect any other test. > > Source/WebDriver/ChangeLog:9 > > + commands.

If we > are using int milliseconds elsewhere, then it's probably better to be > consistent though. The spec explicitly says the tiemout must be an integer in the range 0 to 2^64 - 1. We are doing the same for the script timeouts.

Am I missing something? No, I wondered the same while working on this. That's also why added the ASSERT to ensure the timer is not active (which would mean another command is still waiting for navigations). > > Source/WebKit/UIProcess/Automation/WebAutomationSession.cpp:450 > > + waitForNavigationToCompleteOnPage(*page, optionalPageLoadTimeout ?
