    Test Plan

Manager class


Manager()

Verify that D-Bus object path is created

/xyz/openbmc_project/power/regulators/manager


Verify that D-Bus service/bus name is created

xyz.openbmc_project.Power.Regulators


Verify adds D-Bus match rule to be notified of interfacesAdded signals

Test where phosphor-regulators starts before entity-manager is ready
Test where phosphor-regulators starts after entity-manager is ready


Verify it tries to find the list of compatible system types

Test where entity-manager is ready and list is found
Test where entity-manager is not ready and list is not found


Verify it tries to find and load the config file

Test where config file not found/loaded
Test where config file found/loaded


configure()

Test where config file was loaded

Verify all regulators are configured


Test where config file was not loaded

Verify error message written to journal


interfacesAddedHandler()

Test where message is invalid and does not point at real data
Verify object path read correctly

Verify items in most specific to least specific order


Verify default config file name put at end of list
Verify checks for file names in correct order first to last
Test where first file in list found
Test where middle file in list found
Test where last file in list found
Test where file found in test directory /etc/phosphor-regulators
Test where file found in standard directory /usr/share/phosphor-regulators
