Can you elaborate on what kind of automation will be needed in web-platform-tests to support this?

https://github.com/w3c/web-platform-tests/pull/6897 is adding the infrastructure for some (initially) basic forms of input automation, which could be extended. Will some existing WebDriver API do the job, or do you need something new?

We were thinking about using similar technique as is used by pointer-events tests [1,2]. Those tests are manual tests but they get an automation script injected into them that automates them for Chromium using chrome.gpuBenchmarking API.


Currently our test depends on chrome.gpuBenchmarking.smoothScrollBy to induce a
scroll. So at the very lease we need something like that. But I imagine it can be made to work with pointer{down, move, up} as well to simulate scroll. Is this true sunyunjia@? 


The link for wpt automation seems to be only adding 'click' which is not
enough. It seems our best bet if to do what we originaly planned and then
once WPT has more matching automation then consider changing the tests to
use them and thus be automated across all browsers.

Upstream scroll-boundary-behavior.html to wpt test.

This patch upstreams scroll_boundary_behavior.html to a web-platfrom-test. It
is currently a manual test. It asks users to perform some scroll/drag
behaviors and tap the "Done" button, and then checks the result.

This functionality is currently being added to ChromeDriver and soon the GPUBenchmarking dependency shouldn't be needed after that. I expect to be finished by the end of the month.

sunyunjia@: based on #6, we should check now to see if chromedriver supports what we need to automate this test.
