Blake sent me a pastebin of a patch to run through Try and it looks great! https://treeherder.mozilla.org/#/jobs?repo=try&revision=37886d587866e548fab9db8ce03c623ecf20e470
Are there other tests in this directory that need similar modifications?
Flags: needinfo?(mrbkap)
Yes. I would add a function to that directory's head.js that runs an array of tests (and basically looks like the function `test` in this file) that abstracts out the various things the tests need and call that from all of the tests in this directory. I can write the patch tomorrow if need be.
Flags: needinfo?(mrbkap)
I wonder what the difference is between 55 and 54 to cause this to happen. Are we not preloading processes (and therefore making the "create a new tab and switch to it" slower)? The difference between my patch and the current code is that `BTU.withNewTab` waits for switchTab to finish before continuing.

Either the tab switching became faster or the content process startup in 55 (or both). Since disabling this test made the next one fail and your patch combined with keeping the processes alive fixed all the problems I would bet it's the content process startup. I think Andrew is working on that. Andrew, are there patches that got landed on nightly but did not make it to aurora 54 yet?

I haven't been looking at startup time in particular, I've only been reducing the loading of .jsm files. I don't know if that helps startup speed enough to be noticeable. My patches are blocking bug 1350472. I haven't uplifted any to 54.
Flags: needinfo?(continuation)
Maybe Mike has some ideas of what might have improved with content process startup time?

I'm going to laugh if this ends up fixing the various intermittents in browser_devices_get_user_media_screen.js too.

If not, could the parameter be only an optional boolean to disable this check when needed? But I now see that the browser_webrtc_hooks.js test needs to customize it... So maybe expectNoObserverCalled can be the default value of that testCleanup parameter?

Thanks for removing all this code duplication, I've meant to do it for a while!

That This test takes the current tab, tears it off into a new window, and the closes that window. `withNewTab` expects that the tab it opens remains open throughout the call to `taskFn`. I've changed `runTests` to do its own verison of `withNewTab` but agnostic as to the tab it ends up closing.

(In reply to Florian Quèze [:florian] [:flo] from comment #26) > nit: remove the now unused 'tab' variable. Ah, I see you did that in the next patch.
The whole set of changes looks good to me (ie. r=me), but I'm not convinced we really need the 12 separate changesets; especially when some undo what previous changesets did. And I also don't know how to r+ all of this in mozreview without doing A LOT of clicking around. Also, if you want to get a feel of how this impacts the intermittents, I would suggest using try with a syntax like: try: -b do -p linux64,linux64-asan,linux,macosx64,win32,win64 -u mochitest-bc,mochitest-e10s-bc -t none --rebuild 10 --try-test-paths browser-chrome:browser/base/content/test/webrtc
