1624702 - Write a Picture-in-Picture toggle behaviour test for the durationchange event

Status: RESOLVED FIXED

(Toolkit :: Video/Audio Controls, task, P3)

Description

[Mike Conley (:mconley) (:⚙️)]

Bug 1622919 landed a change that makes the videocontrols UAWidget re-evaluate displaying the Picture-in-Picture toggle on <video> elements that fire the durationchange event.

We should add a test for this. Originally, this seemed to be difficult to test, since mocking out the duration on a video seemed hard, creating a 45 second video for the test seemed like a waste of space in the repository, and generating a 45 second video dynamically seemed really hard.

One idea is to add a new pref that controls the minimum length of video for showing the toggle, and poking that before the test begins. Then, we could switch the <source> on the video between a shorter and longer video to test the behaviour.
