Comment (by jelte):

 Just for clarity, right now it actually works (as in, is contained)
 because we are not doing priming right; we are not using root hints as a
 base for priming, but setting the address of a root server permanently in
 our cache; if we implement priming (one of the first tasks to do when we
 continue work on the resolver, imo), this test *would* send out queries
 (simply for starting a resolver). We will then also need to make priming
 so that we can configure the root hints and set it to localhost where we
 configure a fake root server as well (but currently, as we don't do real
 priming at all, this isn't possible).

 What is running is an actual resolver, and any queries not for l.root-
 servers.net (btw, as a trivial task, shall we change it to f?) sent to it
 would result in actual queries. But it is configured to only listen on
 localhost port 47806, so I don't see this as a problem.

 btw, I've also confirmed this experimentally; I ran this in an environment
 without any network connectivity, and one with network but with running.
 tcpdump reported no network activity, and as vorner already confirmed,
 without (dns) networking, the test succeeds as well.
