Custom transport

You can custom transport class if you want. For example class AgentSIB\JsonRpc\Transports\InternalJsonRpcTransport used for internal requests in tests:

<?php

namespace AgentSIB\JsonRpc\Transports;

use AgentSIB\JsonRpc\JsonRpcServer;

class InternalJsonRpcTransport implements JsonRpcTransportInterface
{
    private $server;

    public function __construct (JsonRpcServer $server)
    {
        $this->server = $server;
    }

    public function sendRequest ($request)
    {
        return $this->server->process($request);
    }
}

Usage:

$server = new JsonRpcServer(new BaseJsonRpcSerializer());
$server->addService(JsonRpcServer::DEFAULT_NAMESPACE, '\\AgentSIB\\JsonRpc\\Services\\FirstJsonRpcService');
$client = new JsonRpcClient(new InternalJsonRpcTransport($server));

Now you can test you server.
