Tests todo:

A - SERVFAIL - should return empty response, ra 0 A - NXDOMAIN - should return SOA A - NOERROR - should return A record - or delegated NS record

Record delegated to self should return SOA record rather than NS delegation

Casing should match on question section, always.

Casing should match on other sections if a direct match? (not required, but efficient for compression pointers)

• www.EXample.COm + example.com = EXample.COm
• EXample.COm + www.example.com = www.EXample.COm
• (this should be taken care of by compression pointer logic, once implemented)

Send malformed packets (both as queries and as answers):

• bad question count, answer count, etc
• bad rdata (too long, too short)
• proper packets, truncated
• randomly twiddled bits
• forward compression pointers
• compression pointers to wrong bits (throw error on non-ascii / unsafe chars)

Test that ANY queries return records of all types matching the domain

Test that A queries only return A records, not others matching the domain

Test that A queries for ANAME-enabled records (but no address) recurse (regardless of general recursion settings).

• 0-anames.example.com
• 1-aname.example.com
• 2-anames.example.com

Generally speaking test the cases of 0, 1, and 2 records of any given type (null case, single case, multi case)
