6"""Client side of the mock adb (i.e. the one called instead of the actual adb).
7
8This file is meant to be put in front of the PATH during integration tests, in
9order to route all the adb calls here and serve them using a pre-configured
10dictionary (epxected commands -> planned responses).
11mock_adb.py is the counterpart of this file, and is meant to be used in the
12unittests for configuring the behavior (i.e. the dictionary) of this script.
