Re: TTML2 test suite and implementation report

Hi Cyril,

I agree – and if possible the test suite should be ready even earlier than Sep 20. 1 week is not much time to verify 141 tests!

I'm actively working on creating presentation tests for all the audio styling attributes.

We also need presentation tests for rw and rh units, and Cyril I wondered if we could find a way to split the work there.

Kind regards,

Nigel

Hi all,

As discussed this morning, in order to meet the earliest possible deadline for publication of the PR, we need to have the test suite and implementation report ready by September 27. Once the test suite is ready, we should leave time for people to actually check their implementations against it. We have 255 features in TTML2. We agreed to test only the additional ones compared to TTML1. This means 255-114 = 141 features. Given the volume, I think we nee to give people a week to check all those tests (possibly produce images to check interop) and update the report. So the test suite should be ready before Sept 20. Do you agree?

How do we organize the development of the test suite:
- Who can provide tests?
- How do we avoid duplicating the work?
- I see that https://github.com/w3c/ttml2-tests contains some tests already, in a validation folder. What does it mean? Do we foresee "validation" tests and "rendering" tests or are they going to be the same?

@Glenn, you indicated that you have many tests already:
 - Can you provide them for August 13?
 - Out of the new 141 features, how many features are tested by your tests? How many feature are missing? Can we distribute the work to create the missing one among other members?

Cyril
