Because of 79704, some of the tests will not work by default because WebCore will short-circuit and not ask the client for permission. The tests need to be rewritten with this in mind, and possibly switch on universal access for file URLs for testing, or check for both 1 (default denied) and 2 (denied).

We skipped these tests on Qt in r111519 to make the bot green. http://trac.webkit.org/changeset/111519
To refactor the tests, I will basically be moving all of the tests from fast/notifications to http/tests/notifications. But the state of the tests seem to be pretty bad. Some of them are disabled, and I'm unsure why. And some tests I think should be deprecated. This bug will be the master bug tracking the effort.
