[webkit-dev] Test flakiness.

[Samuel White]

Hey everyone,

I've noticed the following build message:

Unexpected flakiness: text-only failures (1)
  platform/mac/accessibility/search-predicate-element-count.html [ Failure Pass ]

Oddly, when this test is run ALONE (locally of course), it always passes. Yet, sometimes when run with other tests (say all accessibility tests), it fails. This suggests to me that this test should be considered 'flaky' as order matters (which is odd). What are the criteria for marking a test flaky? Thanks.
