This is the anticipation of value effect Kent Beck mention in its books. The
unit tests help to make incremental improvments and anticipate value. For a
company could be value delivered so customer satisfaction and $$ in the other
hand for an open software community it would be motivation for volunteers/users.

It's good we talk about our volunteering economy because we are not a big number
of people so we must embrace and understood efficiency in this regard,
