    any code to create the corresponding event logs:

    1. Copy the modified message_registry.json into `/etc/phosphor-logging/` on
       the BMC. That directory may need to be created.
    2. Use busctl to call the Create method to create an event log corresponding
       to the message registry entry under test.
