init terminating in do_boot
My knowledge of Erlang is very limited. I run an authoritative DNS server on port 8053, per dnstest.config, and:
% ./run.sh
Erlang/OTP 22 [erts-10.6.4] [source] [64-bit] [smp:12:12] [ds:12:12:10] [async-threads:1]
{"init terminating in do_boot",{undef,[{dnstest,start,[],[]},{init,start_em,1,[]},{init,do_boot,3,[]}]}}
init terminating in do_boot ({undef,[{dnstest,start,[],[]},{init,start_em,1,[]},{init,do_boot,3,[]}]})
Crash dump is being written to: erl_crash.dump...done
Same thing with a more recent:
% ./run.sh
Erlang/OTP 24 [erts-12.3.2.1] [source] [64-bit] [smp:12:12] [ds:12:12:10] [async-threads:1] [jit]
{"init terminating in do_boot",{undef,[{dnstest,start,[],[]},{init,start_em,1,[]},{init,do_boot,3,[]}]}}
init terminating in do_boot ({undef,[{dnstest,start,[],[]},{init,start_em,1,[]},{init,do_boot,3,[]}]})
Crash dump is being written to: erl_crash.dump...done
IMHO, the README is a bit short...
The README is indeed a bit lacking, mostly because this is something that we've used internally for testing erldns, but we haven't had much interest in others to run it, either against erldns or against other systems. I'll see if I can get a team member to give you a hand to figure out how to get it running.
@bortzmeyer - I cannot reproduce locally against the latest dnstest repo with erldns latest running as authoritative locally with default config for both, the test harness runs fine:
Erlang/OTP 24 [erts-12.0.3] [source] [64-bit] [smp:16:16] [ds:16:16:10] [async-threads:1] [jit] [dtrace]

Would you be able to provide the erl_crash.dump to have a look?

@bortzmeyer - apologies for the delay, I had a chance to look at the dump and it only indicates that it cannot find the dnstest module and start() function in it, hence unable to load and execute the code.
Not clear what it is the underlying issue as I cannot reproduce locally, but could you please do the following:
cd dnstest
rm -rf _build
rm rebar.lock
make
sometimes _build/* artefacts get stale and it may cause issues.
Also, try:
./rebar3 shell

i.e. try to load rebar shell and manually execute with 'dnsdist:start()'
Please let me know if this solved the conundrum.

@m0rcq Thanks, after that, it is better. dnstest runs. It is not clear to me how to use it. I run an authoritative name server on port 8053, it receives just one badly formed query (which makes sense, dnstest tries to see how the server will react to wrong packets) but that's all and dnstest stops with a very long message. Here is the beginning:

@bortzmeyer - the test harness is bailing out with {error,timeout,{server,{{127,0,0,1},8053}}} when querying the local authoritative at 127.0.0.1:8053 from what I can see.
Are you running erldns instance locally or it is another nameserver? Also, is dig failing on queries against the same auth instance?
dig has no problem to get an answer. (For a proper query. Of course, unparseable queries are ignored.)
