Status: RESOLVED FIXED

(Remote Protocol :: Marionette, defect, P3)

Description

[Andrew Nicols]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.88 Safari/537.36

Steps to reproduce:

Call the element/click endpoint

Minimal reproduction at https://github.com/andrewnicols/pointOnClick

Actual results:

The element is clicked

The mouse was not moved to the element

Expected results:

According to the W3C specification at https://w3c.github.io/webdriver/#element-click

Step 8 "Otherwise" states:

11: Dispatch a pointerMove action with arguments mouse’s input id, pointer move action, mouse’s input source state, and 0.
12: Dispatch a pointerDown action with arguments mouse’s input id, pointer down action, mouse’s input source state, and 0.
13: Dispatch a pointerUp action with arguments mouse’s input id, pointer up action, mouse’s input source state, and 0.

At present only steps 12, and 13 are completed.

For W3C WebDriver Standards compliance the pointer should be moved to
the click target before the click occurs.

Looks like the test file needs reformatting, but I'm not going to do so in this issue:

Thanks Andrew for filing this issue. The underlying reason here is that at some point the WebDriver spec has been changed and now refers to action primitives. And that hasn't yet been implemented in Marionette. See bug 1490268.

I'm happy to accept a patch that simply emits a mouseover event without implementing all the action primitive specific steps.

Thanks Henrik,

I did wonder whether we should be rewriting to ues the action primitives but I wasn't sure how best to achieve that.

Thanks

No, we shouldn't at this point given that it is way more work. But we are able to easily synthesize a mousemove event. It would only have to be injected at the right position in webdriverClickElement().

W3C specification states that the mouse should be moved before a click occurs, so this test should now be pass. I've updated D100381 to remove the expected failure state of this test as it is no longer accurate.
