Comment 1

[Edwin Takahashi (:egao | infrequent contributor)]

This appears to be a consistent failure that began cropping up on ubuntu1804 image from November 29, 2019 push:
https://treeherder.mozilla.org/#/jobs?repo=try&group_state=expanded&resultStatus=testfailed%2Cbusted%2Cexception%2Cretry%2Cusercancel%2Crunning%2Cpending%2Crunnable&searchStr=web-platform-test%2Clinux64&revision=b02d05a8441067ee2a6fb5ecd83ed3433bcb71c5\

:masayuki - would it be acceptable to add a clause in the manifest file as follows?
if os == 'linux' and version == '18.04': FAIL

Comment 2

[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)]

Do you reproduce it on local environment? If no, I think that it's really odd bug of our driver or test environment. If yes, I could investigate the odd failure reason. Anyway, it's okay to mark it as FAIL.

(In reply to Masayuki Nakano [:masayuki] (he/him)(JST, +0900) from comment #2)

Do you reproduce it on local environment? If no, I think that it's really odd bug of our driver or test environment. If yes, I could investigate the odd failure reason. Anyway, it's okay to mark it as FAIL.

I will attempt to reproduce this in an ubuntu1804 virtual machine, but I may require your assistance to do so if something unexpected arises.

Comment 4

[Edwin Takahashi (:egao | infrequent contributor)]

I've set up a virtual machine with ubuntu1804, configured and performed an artifact build of firefox with current mozilla-central d1001fea6e4c.

With no changes made to the underlying OS other than apt-get update && apt-get upgrade, and necessary build items installed, this is what I got:

 0:20.88 TEST_END: Test OK. Subtests passed 4/4. Unexpected 0
 0:20.88 INFO Pausing until the browser exits

~~~~~~~~~~~~~~~~~
Ran 5 checks (4 subtests, 1 tests)

So it's something to do with the environment, or other tests are interfering with this specific test.

---

For comparison, I re-ran the test directory again to see if other tests are interfering with this particular test:

 1:03.50 TEST_END: Test OK. Subtests passed 1/1. Unexpected 0
 1:03.50 TEST_START: /dom/events/Event-dispatch-redispatch.html

So it seems, at least in the virtual machine environment, this test passes without any issue.

With this information, do you have any other avenues to investigate? I wonder if it may tangentially be related to bug 1543337? Or perhaps mouse events in the ubuntu1804 image is experiencing issues.

If you're OK with the test being marked as FAIL for ubuntu1804, and it begins passing again, at least the web-platform-test harness will inform us that something has changed.

Removing assignment since the bug is now marked as expected failure.
