For the test failures, were you able to get those reliably over a few test runs? I'm curious if these are in random orange territory or if there's something different between our machines that cause this.

    
    

    
  
I ran the tests 3 times and they seemed to fail in the same place each time.

Chatted with mbrubeck about this on irc. I think your test failures are due to running the tests in portrait mode. If not please let me know. Since these tests require a wide screen, we're going to opt out of them if someone runs them in a mode other than landscape.

Could you change this from "info(...)" to "todo(false, ...)"?  Just so it'll be a little more visible in the summary when the tests complete.

It seems odd to create a promise but only resolve it in the if clause. This triggers a warning on sometimes having no return value. However, provided showNavBar is called via a Task.spawn it should handle either eventuality

This makes me think that the appbar should provide its own shown/hidden events rather than making us hook into transitionend (and it you look at ContextUI you'll see there's a further setTimeout after that). But, works for now

All tests should have a .desc property, so we can improve the error message here by including that in the output

We were wondering yesterday if you were running these in landscape mode. Was that the case? I did so and ended up with failures similar to to the log you posted to pastebin yesterday.

    
  
Component: Input → Tests

    
    

    
  
I think I found a flaw in this that when fixed smooths things out. We don't treat touchup like a touchmove when calculating selection in the page. So in the tests, if the difference between TouchDragAndHold's last touchmove and touchend is wide enough such that we don't snap to the right word, tests might fail. DOM's snap seems a bit unpredictable in general. I'll try to work up a test case for this a file a bug on selection. In the mean time though I'm testing some fixes that should improve the reliability of these tests.

check for landscape mode

Could you make the browser_context_menu_tests.js bail out on non-landscape screens too?

    
    

    
  
These failures all seem to stem from latency in message manager. The tests rely on selection manager values (selection state, monocle xPos) while walking through steps in each test.

I've tried compensating for this using purgeEventQueue calls, but this doesn't guarantee all mm events are delivered since one mm message can trigger additional message that a call to purgeEventQueue won't pick up on.

I'll try to add additional state getters to the selection code to help compensate for this.

Can we use a counter instead of an array here?

Basically this is nonzero if there is an operation in progress, and zero otherwise, right?  Could you add a brief comment explaining that?

Changes include:
- listening for scroll completion on page and frame scrolls
- upping various timeouts and requesting more time for the overall test via requestLongerTimeout (for debug builds)
- decreasing the number of touch events sent in TouchDragAndHold to cut down on latency
- added "browser normalize time" header tests for each page load

We were kicking around an idea for ContextUI.dismiss to return a promise that resolves when it is truly done dimissing and transitioning, see #849015

I think that would make things even worse. Opening tabs brings up the context ui and in debug builds, can take a very very long time to complete. The browser also needs to stabilize afterward.

open tab overhead. Really not needed on release builds, but debug builds need a lot of time to "calm down" before the test runs.

sounds good.
Depends on: 849015

    
    

    
  
Maybe after we get tests running in automation and have the time to work on test stability we can revisit this. But currently there's no way tests this complex can run reliably on mc.

This adds some props on SelectionHelperUI for better tracking of state, and a neat ping/pong utility call that can be used to insure all message manager messages have been flushed.

head helpers

For simplicity, I'd prefer to just disable these tests at build time by skipping them in Makefile.in:

  ifndef MOZ_DEBUG
  BROWSER_TESTS += ...
  endif

I think I can carry over the original r+ then from the previous review. Feel free to look this over if you like.

Please add a fixed margin instead of centering. Centering can cause different monitor sizes to react to sendContextMenu* differently.

nit: This is not needed, the yield will throw and this will never be executed in case of an error. Same below.

Is there a condition we could use?

Wow, that's a huge timeout! :) Can we reduce it?

You can use a waitForCondition like in https://mxr.mozilla.org/mozilla-central/source/browser/metro/base/tests/mochitest/browser_context_menu_tests.js?rev=37fd7284be3a#77

Nothing reliable. What we need to do is fix the context menu code such that showing context menus in close succession works reliably. I'm guessing we'll get to this when we work on tracking downthe context menu test failures.

I'd like to give it the extra time, it's a rather large drag. When these ran in debug builds it definitely needed it.
