"""Base class for Bluetooth tests.
BluetoothTest provides a common warmup() and cleanup() function for the
collection of Bluetooth tests that sets the following properties, depending
on the arguments to the test and properties of the test object:
self.device - BluetoothDevice object for the device being tested
self.tester - BluetoothTester object for the device's partner tester
self.interactive - InteractiveClient object for the device
The latter two may be None if the test is initialized from the control file
with the tester_host parameter as None and/or the interactive argument as
It is not mandatory to use this base class for Bluetooth tests, it is for
convenience only. A test with special requirements, or a need to derive
from a different base class, may instantiate and clean-up the associated
objects on its own.
