[asterisk-commits] mmichelson: branch group/dns_naptr r433328 - /team/group/dns_naptr/tests/

[SVN commits to the Asterisk project]

Author: mmichelson
Date: Tue Mar 24 10:55:40 2015
New Revision: 433328

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=433328
Log:
Change test so that they specify lengths of strings.

This allows for me to write off-nominal tests where I can give
incorrect string lengths and see just how badly things blow
up...mwahaha.
