I think "Remove obsolete unit test" is neither true nor should it actually happen: the unit test remains as important, I don't think it is obsolete at all. If it uses an interface that's not the current one then it needs to be adapted. This may be non-trivial, but especially these tests are really important. If the new interface makes it somehow impossible to adapt the test then we've got a problem, because it means we have arrived at a black-box that prohibits testing.

Thank you for updating the unit test! (But it does still require a rebase.)
