///////////////////////////////////////////////////////////////////////////////
// Test Purpose:
//   To verify that pairing process of BluetoothAdapter is correct.
//   Use B2G emulator commands to add/remove remote devices to simulate
//   discovering behavior. With current emulator implemation, the pair method
//   between adapter and remote device would be 'confirmation'.
//
// Test Coverage:
//   - BluetoothAdapter.startDiscovery()
//   - BluetoothAdapter.stopDiscovery()
//   - BluetoothAdapter.pair()
//   - BluetoothAdapter.unpair()
//   - BluetoothAdapter.onpairedstatuschanged()
//   - BluetoothAdapter.setPairingConfirmation()
//
