Where can I find Test::More?

Why does $resolver->query() return undef when the answer section is empty?
The short answer is, do not use query(). $resolver->send() will always return the answer packet, as long as an answer was received.
The longer answer is that query() is modeled after the res_query() function from the libresolv C library, which has similar behavior.
