I believe the intention was to add more tests over time.

I believe the test mode refers to using the test configuration and using
the client port from the incoming packet instead of the well known port.
See the REPLY_TO_SOURCE_PORT option in includes/site.h to enable

See the bottom of tests/DHCPv6/test-a.conf.  There is a stanza of
subnet6 fe80::20c:29ff:fe42:820/128 {
}

You may need to adjust that to use a subnet known to your machine.
