1223298 - [Meta] Increase the testing coverage for AudioChannel

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: AudioChannel, defect)

Description

[Alastor Wu [:alwu]]

In order to increase the test coverage for AudioChannel, use this meta bug to collect the related issues.
Here is our rough plan.

---

In Gecko, we don't want the AudioChannel API affects the normal audio playback. Here are some test items which are collected from the previous regression bugs.

1. Check whether the audio/video playback can work well with the audio focus
   - only one audio channel in the window
   - multiple audio channels in the window
2. Check whether the audio/video would lost the audio focus during the seeking
3. Check the AudioChannel API functionality

---

In Gaia, the mainly task is to test the audio competing behavior. In addition, we'll also need to check the audio channel control functionality.

1. Ensure the audio competing behavior is correct with UX sound spec [1]
2. Check the audio control can work well on different dom windows (ex. attention window, pop-up window)
3. Add tests for sound manager, to ensure the volume control type and playing icon can always be correct

Awesome! 
It is very important to have more test cases to avoid regressions.
