Version
I specifically saw this with 3b1e29c, but I've seen it before with other versions as well.

Platform
This specifically happened with the "api windows firefox jdk21" environment in the CI test harness. I don't know the platform details for that.

Symptom
There seems to be a race condition in the test that causes it to fail randomly.

Reproduction
I have not reproduced it locally. It seems to happen in the CI test suite with some regularity.

Actual behavior
Here's the relevant output from the CI test suite under task test-server:

=== with-driver-tests [jvm]

Expected behavior
The test should pass consistently or fail with an actual hard failure, but not fail randomly.

Diagnosis
I think this is another case of the test suite kicking off an asynchronous action with the browser, the WebDriver returns to the test code, then the test code makes another WebDriver call before the browser is ready, and the browser returns something that the test code is not expecting.

Thanks for raising this. I've only seen it on firefox on windows, you?
My guess is that a new webdriver/browser is being recreated before the last one has a chance to fully terminate. This is probably more of any issue with geckodrive/firefox, but something we can perhaps work around.

I have seen this on MacOS as well (my own machine). I don't remember if it was Firefox or not. I did note that this time, in the CI testbed, it was Firefox. I don't know enough about the low-level details of spawning WebDriver/browsers to know if that could be the cause or not. Are you thinking that there is some state that is shared between the still-dying processes and the newly-created processes? What would that be? Things like sockets numbers aren't being reused, are they? If things are pretty isolated, I'm not sure why creating one before another terminates is an issue. You might want to look and see when the process termination code returns. Is it after things are really cleaned up, or is it returning early. To debug, you could maybe insert waits strategically between things. I actually did a quick REPL test of starting up two Firefox drivers simultaneously on my MacOS machine and that seems to work as expected. Now, obviously, that was not hammering anything hard, with tight timings, but there doesn't seem to be any obvious interference. Note that I got two separate processes here, each with a separate browser window. quit-ing each driver instance (not shown, below) went smoothly as well.

I'm busy with other things these days. If you have the time and interest to explore/solve, go for it!

Just had another variant of the same issue appear as I was trying to debug it. Note in the first case, above, the exception gets thrown from go, but in the this case it's thrown from get-user-agent. Looking at the test code, in both cases, these calls are the first calls right after the creation of the driver with a with-* macro. As with before, Firefox is the browser. This particular failure happened on Windows. I'm not sure if the exception above happened on Windows or not.

I'm going back through errors in prior CI runs and found this one. It's the same rough symptom as the others, but this time it happened while running test-doc. OS/browser is Windows Firefox.

The relevant section from the User Guide is:

;; Start WebDriver for Firefox
(def driver (e/firefox)) ;; a Firefox window should appear
(e/driver-type driver)
;; => :firefox

;; let's perform a quick Wiki session

;; navigate to Wikipedia
(e/go driver "https://en.wikipedia.org/")

The exception was thrown from within the go.

@lread , I'm going to change the title of this issue now that we know that it's not constrained to with-driver-tests. It also seems to be at least focused on Windows Firefox as the OS and browser combination. At least that seems to bring it out more easily. Any issues with that?
