RE: Action 99: Update test_timing_attributes_order test and document_readiness_exists investigations

I started working on this and wonder if we really want to tie this test into Navigation Timing.  The motivation to add the test at TPAC<http://www.w3.org/2010/webperf/track/actions/68> was to create a test to verify the dependency on HTML5.  If we tie it into NT, UAs that have not implemented Navigation Timing yet will fail the test even though they do meet the dependency requirements.  If we don't, we still have the dependency verification, but do not guarantee the validity of the data.  I think this is fine, as we have taken the precedence in other tests to trust the browser to timestamp the attributes correctly and focus on validating proper order.

My vote is to leave the test as is.  What are everyone else's thoughts?

Thanks,
Karen

That sounds like a nice value-add.  I can work on that for next week.

Thanks,
Karen

Hi Karen, Thanks for the updates.

http://w3c-test.org/webperf/tests/submission/Microsoft/NavigationTiming/test_timing_attributes_order.htm

Looks good to me.

http://w3c-test.org/webperf/tests/submission/Microsoft/NavigationTiming/test_document_readiness_exist.html

This test checks that document.readyState has the right value at the right time. That's fine, but isn't related to Navigation Timing. To make it relevant, we should verify that each of performance.timing.{domLoading,domInteractive,domComplete} are 0 prior to reaching each readiness phase and are >0 after reaching it.
