This line is pointless. We know how to run tests :-) Please remove.

Please see my reply to your other patch regarding patch formatting.

In review to v1 I asked you to fold this test in box-tap/cfg.
Any reason why this couldn't/shouldn't be done?

No, that's not what I meant. Using a random port like that won't save

Nit: I'd just inlined both of these functions.

Bad indentation. We use 4 spaces in Lua, never tabs. Please configure
your editor appropriately and fix this test.
