// For these tests we use a fake DBus daemon to verify powerMonitor module

// interaction with the system bus. This requires python-dbusmock installed and
|
||
|
|
// running (with the DBUS_SYSTEM_BUS_ADDRESS environment variable set).
|
||
|
|
// script/test.py will take care of spawning the fake DBus daemon and setting
|
||
|
|
// DBUS_SYSTEM_BUS_ADDRESS when python-dbusmock is installed.

// See https://pypi.python.org/pypi/python-dbusmock for more information about

// python-dbusmock.
