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