It should, assuming you have the necessary network connectivity between
nsfoo and nstest, and that nstest allows nsfoo to query it. Be aware,
however, that if nsfoo has the answer cached, then it doesn't *need* to
forward the query to nstest. So not every query for a "test.bar.com"
name will necessarily generate a forwarded query -- only the uncached
ones will.

What's a "forward RR"?
