// 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).
