Comment:

 Can you provide a review of current practices regarding unit testing? It
 seems that Tor codebase does not rely on external frameworks/libraries for
 unit testing and has its own testing infrastructure.

 To implement unit test, do I need to create several instances of
 `routerinfo_t` structs, process them with
 `router_dump_exit_policy_to_string()` and use `tor_assert()` to see if I
 am getting the correct output? Should this code be placed in
 test/test_dir.c?

 Regarding IPv6 exit policies, do we need to implement `GETINFO exit-
 policy/ipv6`? What if torrc define both IPv4 and IPv6 exit policy entries?
 Maybe we need to implement `GETINFO exit-policy/ipv4` to get IPv4-only
 entries as well. In that case, `GETINFO exit-policy` should return all
 (both IPv4 and IPv6) entries.
