We currently do not have tests in web-platform-tests.
There are tests outside the external/wpt folder:
third_party/blink/web_tests/editing/input/edit-context.html<https://source.chromium.org/chromium/chromium/src/+/main:third_party/blink/web_tests/editing/input/edit-context.html>
third_party/blink/web_tests/editing/input/edit-context-dom-mutation.html<https://source.chromium.org/chromium/chromium/src/+/main:third_party/blink/web_tests/editing/input/edit-context-dom-mutation.html>

I'm going to migrate as much of the contents of these as I can to WPT. This 
won't be possible for a lot of the subtests since they rely on primitives like 
eventSender and textInputController, which aren't available in WPT.
There is also test coverage that still needs to be written for scenarios 
involving nested editable elements, and I plan to add these as WPTs.

There's been some work 
done<https://chromium-review.googlesource.com/c/chromium/src/+/3009937> around 
adding support for IME testing but my understanding is that more work is needed 
in order to use this in WPTs.

Do you all have a timeline in mind for experimentation?

Summary

The EditContext API simplifies the process of integrating a web app with 
advanced text input methods such as VK shape-writing, Handwriting panels, 
speech recognition, IME Compositions etc., improves accessibility and 
performance, and unlocks new capabilities for web-based editors.

Risks



Interoperability and Compatibility

There are no known interop or compat risks.


Gecko: No signal

WebKit: No signal

Web developers: Strongly positive Positive feedback from Word online, Adobe and 
Figma, Google Docs

Other signals:


Activation

Developers interested in this feature will typically have their own polyfill 
for text input using hidden textarea or contenteditable elements. Feature 
detecting and using new API to avoid side effects of previous approaches is 
intended to be easily adoptable.



WebView application risks

None

Goals for experimentation
We are looking for feedback on the developer ergonomics of using the API and 
for confirmation that it meets the needs of production web apps for various 
input modes. This is a complex API, and different developers are expected to 
use it in different ways. For example, some partners plan to construct the view 
of their editable region in the subtree of the EditContext-associated element, 
while other partners plan to keep the EditContext-associated element off-screen 
while using the EditContext APIs to set the bounds of the editable region.

We want to ensure that our design enables all these scenarios and is robust 
given the wide field of IMEs utilized by different users, which may have subtly 
different behaviors and event timings.


Ongoing technical constraints

None



Debuggability
Existing DevTools functionality should suffice to debug EditContext.
Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, 
Chrome OS, Android, and Android WebView)?
Yes


Is this feature fully tested by 
web-platform-tests<https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?
No


Flag name
--enable-blink-features=EditContext


Requires code in //chrome?
False


Tracking bug
https://bugs.chromium.org/p/chromium/issues/detail?id=999184


Estimated milestones
