If not, is smoke testing still used?
It's sort of a Venn Diagram. Some Automated tests are Smoke tests, and some smoke tests are Automated (inasfar as they are ran by a computer program). A Smoke test is a take off (if I recall correctly) on the term "Where there's smoke, there's usually fire." It's a set of preliminary tests that the program must pass to be considered for 'real' (viz. fire) testing.
A smoke test can be manual insomuch as a tester has a list of steps he follows, but these aren't automated with a computer program.
Smoke testing is still used -- in places I've worked, it's usually automated.
