New Revision: 433317
URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=433317
Log:
Add a test file for NAPTR tests.
This test contains a mock resolver that can generate DNS answers for
NAPTR queries. Currently, it can only generate nominal results. It will
be tweaked further once off-nominal test cases are required.
