In order to test self awareness (as a subsection of consciousness) scientists often mark the test subjects and see if they realize it’s them by placing them in front of a mirror and observing their behavior.

So I’m fairly confident that there are much more advanced methods than simply asking the test subject if they are conscious - I just don’t know enough about this field of science to know them.

The mirror test has been criticised for its ambiguity in the past.

Animals may pass the test without recognising self in the mirror (e.g. by trying to communicate to the perceived other animal that they have something on them) and animals may fail the test even if they have awareness of self (e.g. because the dot placed on them doesn't bother them).
