These are usually not the tests of dnspython.

dnspython even has some support for using a different file instead of 
/etc/resolv.conf, the problem is that there are several other packages
in the callstack before dnspython in these failing tests.

Note that even if you would be mocking /etc/resolv.conf, you'd still 
have to add a nameserver IP address in the mocked /etc/resolv.conf
At that point you might as well install the mocked resolv.conf
as /etc/resolv.conf in build environments.

This is mocking the C library functionality,
which is not used by dnspython.
