<?php 
namespace Service;

class TwitterAPI
{
    private $httpClient;

    public function __construct($httpClient = null)
    {
        $this->httpClient = $httpClient;

        // assuming \HttpClient is defined...
        if ($httpClient === null) $this->httpClient = new \HttpClient();
    }

    public function getStatuses
    {
        // simplified for the purposes of illustration
        return $this->httpClient->get('statuses/user_timeline');
    }
    
    // etc...
}
