Help required to test some Negative Responses from Bind Server.

[Harshith Mulky]

Hello Experts,


As a tester who is testing a client(lwres) developed on same bind stack.

I would want to generate scenarios and test how the client responds when the bind server responds with negative Responses


I was able to test Negative response like NXDOMAIN as it was straight forward where a record is not present in particular Domain file


I would want to test a scenario where bind Server responds with the following Response Codes


1. SERVFAIL

2. REFUSED

3. Receiving NOERROR, but no RR in response

4. NOTIMP


If I have a basic Zone file like this, Can I be able to test the above 4 scenarios
