As far as I'm concerned, the only priority here should be for things which can already be tested only with standard APIs (i.e. the idlharness tests, looks like maybe all of fast/imagecapture?).  Those should be pretty easy to upstream, right?  Any chance we can get an owner for that with Pri=2?

There's a lot of (both technical and non-technical) issues to work out generally for interop testing of things that require automation/mocking.  I'm definitely not going to argue that solving that for ImageCapture should be a priority.

#5, why is this blocked on upstreaming WebUSB tests?

#6: once WebUSB teaches how to plug the mojo mock service we can 
reuse the same arcanes for the Image Capture. 

This issue has been Available for over a year. If it's no longer important or seems unlikely to be fixed, please consider closing it out. If it is important, please re-triage the issue.

Sorry for the inconvenience if the bug really should have been left as Available.

Still available - also WebUSB already upstreamed a JS+mojo mock, so this
brug should be addressed.

Upstream image_capture tests to WPT


Moved the layout tests under third_party/WebKit/LayoutTests/imagecapture/ to
third_party/WebKit/LayoutTests/external/wpt/mediacapture-image/

Moved the layout tests under fast/imagecapture to wpt and suffixed some file names with
-fast.html to avoid name collision.
ImageCapture-creation.html was renamed to
ImageCapture-creation.https.html as it needed to be served over https

Moved third_party/WebKit/LayoutTests/imagecapture/resources/imagecapture-helpers.js to
third_party/WebKit/LayoutTests/external/wpt/mediacapture-image/resources/imagecapture-helpers.js
and extended it by adding a wrapper promise test, image_capture_test.

Copy the auto generated image_capture.mojom.js to wpt/resources/chromium/mock-imagecapture.js
used a flag called "scramble_message_ids = false" to the mojom compiler.

Used the testharness from wpt/

No new tests have been added.
