///////////////////////////////////////////////////////////////////////////////
// Test Purpose:
//   To verify that all setters of BluetoothAdapter (except for pairing related
//   APIs) can change properties correctly.
//
// Test Procedure:
//   [0] Set Bluetooth permission and enable default adapter.
//   [1] Verify the functionality of 'setName'.
//   [2] Verify the functionality of 'setDiscoverable'.
//   [3] Disable Bluetooth and collect changed attributes.
//   [4] Verify the changes of attributes when BT is disabled.
//   [5] Set properties when Bluetooth is disabled.
//   [6] Enable Bluetooth and collect changed attributes.
//   [7] Verify the changes of attributes when BT is enabled.
//   [8] Restore the original 'adapter.name'.
//   [9] Check the validity of setting properties to their present value.
//
// Test Coverage:
//   - BluetoothAdapter.setName()
//   - BluetoothAdapter.setDiscoverable()
//   - BluetoothAdapter.onattributechanged()
//   - BluetoothAdapter.state
//   - BluetoothAdapter.name
//   - BluetoothAdapter.discoverable
//
