Ignore presentation time if visibility changed, for Event Timing EventTiming registers for presentation feedback times for events which are expected to have a visual update. However, if page visibility changes, that can affect the time it takes to present the next paint update. We were already ignoring the time to next paint portion for UKM reporting of interactions, but now we also ignore this time for Event Timing reporting to Web Performance timeline. Filed a spec issue with EventTiming API to clarify cases where events will not have a next paint: https://github.com/w3c/event-timing/issues/123 Also, we will follow-up to see if it is not desirable to measure all the way until visibility change, as per: https://github.com/w3c/event-timing/issues/129 Bug: 1312568 Change-Id: Iee0b5eee81fb216a96ecbfcc41ca26601ab6ba1b Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/3926369 Commit-Queue: Michal Mocny <mmocny@chromium.org> Auto-Submit: Michal Mocny <mmocny@chromium.org> Reviewed-by: Noam Rosenthal <nrosenthal@chromium.org> Cr-Commit-Position: refs/heads/main@{#1093452}
The web-platform-tests Project is a cross-browser test suite for the Web-platform stack. Writing tests in a way that allows them to be run in all browsers gives browser projects confidence that they are shipping software that is compatible with other implementations, and that later implementations will be compatible with their implementations. This in turn gives Web authors/developers confidence that they can actually rely on the Web platform to deliver on the promise of working across browsers and devices without needing extra layers of abstraction to paper over the gaps left by specification editors and implementors.
The most important sources of information and activity are:
wpt:matrix.org
matrix channel; includes participants located around the world, but busiest during the European working day.If you'd like clarification about anything, don't hesitate to ask in the chat room or on the mailing list.

Note: because of the frequent creation and deletion of branches in this repo, it is recommended to “prune” stale branches when fetching updates, i.e. use git pull --prune
(or git fetch -p && git merge
).
See the documentation website and in particular the system setup for running tests locally.
The wpt
command provides a frontend to a variety of tools for working with and running web-platform-tests. Some of the most useful commands are:
wpt serve
- For starting the wpt http serverwpt run
- For running tests in a browserwpt lint
- For running the lint against all testswpt manifest
- For updating or generating a MANIFEST.json
test manifestwpt install
- For installing the latest release of a browser or webdriver server on the local machine.wpt serve-wave
- For starting the wpt http server and the WAVE test runner. For more details on how to use the WAVE test runner see the documentation.On Windows wpt
commands must be prefixed with python
or the path to the python binary (if python
is not in your %PATH%
).
python wpt [command]
Alternatively, you may also use Bash on Ubuntu on Windows in the Windows 10 Anniversary Update build, then access your windows partition from there to launch wpt
commands.
Please make sure git and your text editor do not automatically convert line endings, as it will cause lint errors. For git, please set git config core.autocrlf false
in your working tree.
The master branch is automatically synced to wpt.live and w3c-test.org.
Save the Web, Write Some Tests!
Absolutely everyone is welcome to contribute to test development. No test is too small or too simple, especially if it corresponds to something for which you've noted an interoperability bug in a browser.
The way to contribute is just as usual:
git checkout -b topic
../wpt lint
as described above.If you spot an issue with a test and are not comfortable providing a pull request per above to fix it, please file a new issue. Thank you!
