Implement W3C Actions API

[jgraham]

The marionette backend for this is tracked in https://bugzilla.mozilla.org/show_bug.cgi?id=1292178
The WebDriver API patch is in https://github.com/jgraham/webdriver-rust/tree/actions

This blocks SeleniumHQ/selenium#2285

Can this be given some love, we have been stuck with FF 47.0.1 because we have lot of tests which depend on moveto and doubleclick.

Strange, but before Marionette, I don't remember technology name (maybe XUL Runner), this feature was working. Now I'm getting error POST /session/0856e028-504a-7bd9-8198-d9dbc706f291/moveto did not match a known command.

Is there any plan to start to develop the Move To any time soon? Is there a development schedule plan? Would I be able to help the community develop this?

[jgraham]

We are aware that this is a high priority for many people and we are actively working on implementing the W3C standard API. Locking the issue to prevent more me-too comments.

The relevant routing pieces have now landed in webdriver-rust and geckodriver. Parsing action chains and basic dispatching of keys have landed in Marionette.

Firefox 52 (53?) onwards contains a mostly specification-conforming implementation of the W3C WebDriver actions API. I believe the Selenium language bindings are doing work to support this.

@mjzffr, can you give an update on the progress of this?

[mjzffr]

Firefox 52 Release and Firefox 52 ESR provide a mostly-conforming implementation with geckodriver 0.15 for key actions, pause, pointer actions (pointerType: mouse).

Some fixes have been made beyond that and will be available with geckodriver 0.16 in Firefox 55, 54, mostly in 53 and the next ESR52.

Highest priority is to fix known issues with some synthesized key events (https://bugzilla.mozilla.org/show_bug.cgi?id=1332279) and mouse click with navigation (https://bugzilla.mozilla.org/show_bug.cgi?id=1345653) and to grow the existing suite of wdspec web-platform tests.

Support for pen and touch pointerType will come next.

Closing this now as there is just follow up work that will happen in bugzilla. Selenium client bindings have been updated.
