In most other places, you seem to do a separate pub.stderr.expect call for each
line. Why not here?

[nweiz, 2014/02/18 22:01:10]

The places with two expect calls have `JSON.encode(body)` as the second
expression rather than a literal string, so I thought the separate calls were a
little cleaner than interpolation. I could switch them to interpolation if you
prefer that.

I don't have a strong preference I just thought the tests seemed inconsistent.

     pub.shouldExit(1);
   });
