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)
|
|

### Variables
|
|
|
|
```
|
|
port=65053
|
|
ns=localhost
|
|
|
|
# For the sake of accuracy, it's most important to test with the standard unix dig tool
|
|
digcmd="dig"
|
|
|
|
# For the sake of completeness, it's important to test with our very own dig tool
|
|
#digcmd="node bin/dig.js"
|
|
```
|
|
|
|
### Run the server
|
|
|
|
```
|
|
# Serve:
|
|
node bin/digd.js +norecurse -p $port --input sample/db.json
|
|
```
|
|
|
|
