# NAME
Test::TCP - testing TCP program
# SYNOPSIS
use Test::TCP;
my $server = Test::TCP->new(
code => sub {
my $port = shift;
...
},
);
my $client = MyClient->new(host => '127.0.0.1', port => $server->port);
undef $server; # kill child process on DESTROY
Using memcached:
use Test::TCP;
my $memcached = Test::TCP->new(
code => sub {
my $port = shift;
exec $bin, '-p' => $port;
die "cannot execute $bin: $!";
},
);
my $memd = Cache::Memcached->new({servers => ['127.0.0.1:' . $memcached->port]});
...
And functional interface is available:
use Test::TCP;
test_tcp(
client => sub {
my ($port, $server_pid) = @_;
# send request to the server
},
server => sub {
my $port = shift;
# run server
},
);
# DESCRIPTION
Test::TCP is test utilities for TCP/IP programs.
# METHODS
- test\_tcp
Functional interface.
test_tcp(
client => sub {
my $port = shift;
# send request to the server
},
server => sub {
my $port = shift;
# run server
},
# optional
port => 8080,
max_wait => 3, # seconds
);
- wait\_port
wait_port(8080);
Waits for a particular port is available for connect.
# OO-ish interface
- my $server = Test::TCP->new(%args);
Create new instance of Test::TCP.
Arguments are following:
- $args{auto\_start}: Boolean
Call `$server->start()` after create instance.
Default: true
- $args{code}: CodeRef
The callback function. Argument for callback function is: `$code->($pid)`.
This parameter is required.
- $args{max\_wait} : Number
Will wait for at most `$max_wait` seconds before checking port.
See also [Net::EmptyPort](http://search.cpan.org/perldoc?Net::EmptyPort).
_Default: 10_
- $server->start()
Start the server process. Normally, you don't need to call this method.
- $server->stop()
Stop the server process.
- my $pid = $server->pid();
Get the pid of child process.
- my $port = $server->port();
Get the port number of child process.
# FAQ
- How to invoke two servers?
You can call test\_tcp() twice!
test_tcp(
client => sub {
my $port1 = shift;
test_tcp(
client => sub {
my $port2 = shift;
# some client code here
},
server => sub {
my $port2 = shift;
# some server2 code here
},
);
},
server => sub {
my $port1 = shift;
# some server1 code here
},
);
Or use OO-ish interface instead.
my $server1 = Test::TCP->new(code => sub {
my $port1 = shift;
...
});
my $server2 = Test::TCP->new(code => sub {
my $port2 = shift;
...
});
# your client code here.
...
- How do you test server program written in other languages like memcached?
You can use `exec()` in child process.
use strict;
use warnings;
use utf8;
use Test::More;
use Test::TCP 1.08;
use File::Which;
my $bin = scalar which 'memcached';
plan skip_all => 'memcached binary is not found' unless defined $bin;
my $memcached = Test::TCP->new(
code => sub {
my $port = shift;
exec $bin, '-p' => $port;
die "cannot execute $bin: $!";
},
);
use Cache::Memcached;
my $memd = Cache::Memcached->new({servers => ['127.0.0.1:' . $memcached->port]});
$memd->set(foo => 'bar');
is $memd->get('foo'), 'bar';
