I implemented initial TestDriver support for get_accessibility_properties_for_element and get_accessibility_properties_for_accessibility_node in web-platform-tests/wpt#55784. However, I didn't implement the WebDriver parts of this in that WPT pull request because WPT talks to Gecko using Marionette directly, rather than using WebDriver. Thus, there is no WebDriver implementation yet for me to test against. Once another browser supports this with WPT via WebDriver, we will need to teach WPT how to call these methods via WebDriver. This will also involve adding WebDriver CLI tests in /webdriver/tests/classic, similar to the existing tests in /webdriver/tests/classic/get_computed_label/ and /webdriver/tests/classic/get_computed_role/.
See WICG/aom#203 (comment) for a discussion regarding the naming of the WebDriver protocol commands.
