Author: file Date: Thu Feb 26 06:23:07 2015 New Revision: 6467 URL: http://svnview.digium.com/svn/testsuite?view=rev&rev=6467 Log: testsuite: Add DNS server pluggable module.
This change adds a pluggable module to the testsuite which runs a DNS server using twisted-names. This is an authoritative DNS server that responds with records which are specified in a Python style zone file or a BIND style zone file. The DNS server lives for the lifetime of the test. This is useful since it removes any reliance on an external DNS server and reduces the work required to test DNS.
