    Test plan for DBusSensor class


src/sensors.hpp

Verify sizeof(SensorType) == 1
Verify toString(SensorType) still works (regression)


src/dbus_sensor.*

DBusSensor()

Verify 4 args to getTypeBasedProperties are returned successfully

objectPath
unit
minValue
maxValue


Verify that 2 associations are returned successfully

"chassis", "all_sensors", 
"inventory", "sensors", 


Verify that no signals are emitted until object is completely initialized
Verify value is set correctly
Verify maxValue is set correctly
Verify minValue is set correctly
Verify unit is set correctly
Verify functional is set to true
Verify available is set to true
Verify all associations are created successfully
