Given that the domain-specific language in #1467 is merged, why not use that? It also supports replacing the root hints on the fly for subsequent scenarios.

@matsduf @marc-vanderwal thanks, I have updated the unit tests and this PR is now ready for review. In particular, see the handling of specific root hints for scenarios NO-SPF-ROOT-ZONE, NULL-SPF-ROOT-ZONE, NON-NULL-SPF-ROOT-ZONE in t/Test-zone11.t where everything is in one file but requires a bit more code.

Have you considered using the model introduced in #1467 instead?

Unfortunately no, just because I am not familiar with it yet and we are on a short deadline. I will start using it for next releases though !

I would like to see standard unit test files before merge. Else this PR is fine.
