I think so. That describes how I use test doubles more than any other
way. I would call these "fakes" rather than "mocks" because they're
just faking data rather than checking expectations. They're no less
useful for that, though. The terminology just helps to make you
description clear when talking with other people.

Some mock frameworks can work with concrete classes, and some are
restricted to interfaces. I haven't kept up with all the frameworks,
but I think you'll find plenty that can do that for you.
