Ruby doesn't have abstract classes. You can have a base class that you
don't _intend_ to instantiate directly, but there's nothing stopping
you from doing so, so it's not like an abstract class in java, which
you actually can't instantiate directly.
I've seen some cases where the initialize method is made private so
you can't just call Foo.new, so it sort of feels like an abstract
class, but even in that case you can still use send() to instantiate
one in a test:

Yes, you can. I'd either do that, or use a shared example group and
apply it to all of the subclasses (see

Mocks are for specifying interactions between objects, which is a
different situation than you are describing.
