Change the behavior of clonable to be more opt-in See the discussion here: https://github.com/whatwg/html/issues/10107#issuecomment-1921837943 The existing *shipped* behavior (i.e. before the `clonable` concept was introduced) was that any declarative shadow root *within a `<template>`* would be automatically cloned, but no others. The semi-new behavior is the `clonable` bit concept, in which all declarative shadow roots have their `clonable` bit set to true, so they automatically get cloned by `cloneNode()`. That's regardless of whether they are inside or outside a template. The new consensus is that the "semi-new" clonable behavior is likely web-incompatible, because clones will just start getting shadow roots included. Plus it wasn't very developer-desirable. The new consensus is therefore to add a `shadowrootclonable` attribute for declarative shadow dom that allows a shadow root to opt-in to this behavior, but the default for all shadow roots will be `clonable=false`. This CL implements the new consensus behind the ShadowRootClonable flag. If the flag is false, the "shipped" behavior will be emulated via setting `clonable` in an equivalent way. See these three spec PRs: https://github.com/whatwg/dom/pull/1246 https://github.com/whatwg/html/pull/10069 https://github.com/whatwg/html/pull/10117 Bug: 1510466 Change-Id: Ice7c7579094eb08b882c4bb44f93045f23b8f222 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/5260748 Reviewed-by: David Baron <dbaron@chromium.org> Auto-Submit: Mason Freed <masonf@chromium.org> Commit-Queue: Mason Freed <masonf@chromium.org> Cr-Commit-Position: refs/heads/main@{#1258910}
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!
