1398933 - test-verify sometimes times out

Status: RESOLVED FIXED

(Testing :: General, defect)

Description

[Geoff Brown [:gbrown] (pto Apr 11-18)]

We expect test-verify to sometimes have more tests to verify than it can verify in a reasonable amount of time. In these cases, test-verify should give up and complete before timing out.

I see some exceptions, where the job runs for too long.

This is a merge, so having lots of tests to verify is not unexpected.

We triggered "Verification too long", but didn't stop verification:

toolkit/components/extensions/test/mochitest/test_ext_notifications.html
...
[task 2017-09-09T11:28:26.407889Z] 11:28:26     INFO - TinderboxPrint: Verification too long: Not all tests were verified.<br/>
...
intl/l10n/test/test_localization.js

I think it bailed out of one suite (mochitests) but continued with the next suite (xpcshell tests).

Attachment: bail out of nested loop when verify max time exceeded

A small fix for a small problem!
