Sure, absolutely. I agree that we could construct a battery of tests such that any entity passing should be given the benefit of the doubt and treated as though it were conscious: granted human (or AI) rights, allowed self-determination, etc.
> I don't even know that other humans are conscious entities
Exactly. Note that the claim Retra is making (to which I was responding) was very much stronger than this. He is arguing not just that we should generally treat beings that seem conscious (including other people) as if they are, but that they must by definition be conscious, and in fact that it is a self-contradictory logical impossibility to speak of a hypothetical intelligent-but-not-conscious creature.
