the implementations providing the interface being tested. UnitTest
doesn't support this amazingly well but we can do it. I like that we
can do it but the amount of copy&paste required to do it should be
Separately there are some tests that want a transport, but don't need to
be repeated for every one. Many of the tests that create repositories
are like this.

before for the particular case of _offsets_to_ranges a couple of
examples as doctests would help explain it.
And in general if you don't know how to test something it's much better
