If you transform values, then it has logic, so it does not fit in my definition of simple plumbing. If you check that integer value AgencyId is passed to another object as integer value with the same name of AgencyId that is basic plumbing that should not be covered by unit test. Of course someone might forget to wire that up somewhere, but it is not something I would say writing test and then maintaining it costs more than just fixing it when you find it and once it is fixed there is no real reason to keep regression on it.
