These are useful to have as well, but put them in a separate test so that
they can be enabled/disabled independent of the others.  For now you can
write tests using whatever domain data is easy for you to test with locally.
When you post the tests you can show me the relevant records (e.g. dig output)
and then I can fix up the names in the test data with more permanent names
when I install them.

That is fine for xtests.
