12 // This class is a simple mock around AudioManager, used exclusively for tests,
13 // which has the following purposes:
14 // 1) Avoids to use the actual (system and platform dependent) AudioManager.
15 // Some bots does not have input devices, thus using the actual AudioManager
16 // would causing failures on classes which expect that.
17 // 2) Allows the mock audio events to be dispatched on an arbitrary thread,
18 // rather than forcing them on the audio thread, easing their handling in
19 // browser tests (Note: sharing a thread can cause deadlocks on production
20 // classes if WaitableEvents or any other form of lock is used for
21 // synchronization purposes).
