If you don't write a client script yourself, A-T automatically generates
one which simply passes the output of the response module through to
Test::Harness, so you're fine either way.

I think this makes it sound trickier than it needs to; AIUI the feeding 
results back to Test::Harness is nothing to do with what syntax you use 
the response handler module, it's simply that once the (possibly
autogenerated) client script gets hold of the response, it doesn't 
with any interpretation, rather it just passes it straight on to

It's just a question of which side of the HTTP bit you decide to stick 
test logic. You can even mix it up (probably a bad idea, though ;-)).

If I get time I'll try to draw it; I think that would probably help a

Alternatively, you could decide that you want to keep the test logic in 
client script (the .t bit), and just output a page containing
"DB Server: foo" in the response handler. The client script could then 
this. It's just that it's simpler in this case to stick the actual test 
in the handler as well, as Geoff suggested.

Amen to that!
