NAME
   Test::Net::Connect - Test::Builder based tests for network connectivity

VERSION
   Version 0.03

SYNOPSIS
       use Test::Net::Connect tests => 3;

       connect_ok({ host => 'smtp.example.com', port => 25,
                    proto => 'tcp' }, 'Check tcp://smtp.example.com:25');

       # proto defaults to 'tcp', the test name can be omitted, and the
       # port can be appended to the host name
       connect_ok({ host => 'smtp.example.com:25' });

       connect_not_ok({ host => 'localhost:23' },
                      'Telnet connections should not be accepted locally');

   Test::Net::Connect automatically exports "connect_ok()" and
   "connect_not_ok()" to make it easier to test whether or not a network
   connection can be made from this host to a port on another host using
   TCP or UDP.

   Test::Net::Connect uses Test::Builder, so plays nicely with
   Test::Simple, Test::More, and other Test::Builder based modules.

FUNCTIONS
 connect_ok($spec, [ $test_name ]);
   connect_ok() tests that a connection to a host, given in $spec, can be
   made.

   The specification is a hashref that contains one or more keys. Valid
   keys are "host", "port", and "proto". Each value associated with the key
   is the value that entry is supposed to have.

   host
       Specifies the hostname or IP address to connect to. If a hostname is
       given then the A records for that host will be retrieved and
       connections will be made to all the A records in turn. If any of
       them fail then the test fails.

       "host" is mandatory.

   port
       Specifies the port to connect to. The port may also be specified by
       appending a colon ":" and the port number to the "host" value. If
       this is done then "port" is optional, otherwise "port" is mandatory.

   proto
       The protocol to use. "tcp" and "udp" are the only valid values. This
       key is optional, and defaults to "tcp" if it is not specified.

   The $test_name is optional. If it is not present then a sensible one is
   generated following the form

       Connecting to $proto://$host:$port

 connect_not_ok($spec, [ $test_name ]);
   connect_not_ok() tests that a connection to a host, given in $spec, can
   not be made.

   The arguments are handled in the same manner as for connect_ok().

   NOTE: connect_not_ok() will fail ("not ok") if the given host is not in
   the DNS. DNS.

EXAMPLES
   Verify that port 25 can be reached on all the A records for
   "smtp.example.com".

       connect_ok({ host => 'smtp.example.com', port => 25,
                    proto => 'tcp' }, "Checking mail to smtp.example.com");

   Do the same thing, but shorter.

       connect_ok({ host => 'smtp.example.com:25' });

   Verify that the local SSH daemon is responding.

       connect_ok({ host => '127.0.0.1:22' });

   Verify that the host www.example.com is not running a server on port 80.

       connect_not_ok({ host => 'www.example.com:80' });
