1611021 - Add content testing API to simulate media control key events

Status: RESOLVED FIXED

(Core :: Audio/Video: Playback, task, P2)

Description

[Alastor Wu [:alwu]]

Although we already have ChromeUtils.generateMediaControlKeysTestEvent() which can be used to generate events, but that can only be used in the scope with chrome privilege.

We would like to have a testing API which can be used easily in mochitest without having privilege.

Attachment: Bug 1611021 - part1 : add a method in special power to generate media control key events.

It allows us to simulate media control key events in non-privileged context, such as a mochitest running in content process.

Attachment: Bug 1611021 - part2 : align some event names in MediaControlKeysTestEvent with MediaSessionAction's action name.

It allows us to share the same event name when write testing code like following,

const action = "previoustrack";
mediaSession.setActionHandler(action, () => { ... });
specialPower.generateMediaControlKeyTestEvent(action);
