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' });
