///////////////////////////////////////////////////////////////////////////////
// Test Purpose:
// To verify that all properties of BluetoothDevice is correct when they've
// been discovered by adapter and delivered by BluetoothDeviceEvent.
// Testers have to put the B2G devices in an environment which is surrounded
// by N discoverable remote devices. To pass this test, the number N has to be
// be greater than (or equal to) EXPECTED_NUMBER_OF_REMOTE_DEVICES.
//
// Test Procedure:
// [0] Set Bluetooth permission and enable default adapter.
// [1] Start discovery.
// [2] Wait for 'devicefound' events.
// [3] Type checking for BluetoothDeviceEvent and BluetoothDevice.
// [4] Attach the 'onattributechanged' handler for the first device.
// [5] Fetch the UUIDs of the first device.
// [6] Verify the UUIDs.
// [7] Stop discovery.
//
// Test Coverage:
// - BluetoothDevice.address
// - BluetoothDevice.cod
// - BluetoothDevice.name
// - BluetoothDevice.paired
// - BluetoothDevice.uuids
// - BluetoothDevice.onattributechanged()
// - BluetoothDevice.fetchUuids()
// - BluetoothDeviceEvent.address
// - BluetoothDeviceEvent.device
