[webkit-dev] Bug numbers in TestExpectations

[Alexey Proskuryakov]

I've been repeatedly finding it that bug numbers in TestExpectations don't lead to bugs that are helpful in the context of the specific test. Often the bug doesn't have any information beyond what's already in the expectation (that the test is skipped of failing, without a posted diff or any other useful detail). Other times, the linked bug is one that the person was working on at the time of changing expectations, so the bug link is more like "see related bug XXXX, and try to figure out how exactly it's related", not "this failure is tracked by XXXX". Free form comments worked great for both cases in Skipped files.

It appears that the rigid format that requires putting a bug URL is causing more harm than good in practice. I suggest making the URL optional.
