title: Composer autoload not work properly
body: <p>I have following problem: I have class Router (in project/connection/api/callbacks) and TestRouter (in project/tests/api).</p>
  
  <p>Class Router is only Example and I don't want psr-0 or 4.</p>
  
  <p>Router has this code on the beginning:</p>

  <p>Test class start with this code:</p>
  
  <pre><code>&lt;?php
  
  $loader = require __DIR__ . '/../../vendor/autoload.php';
  $loader-&gt;add('Connection\\Api\\Callbacks', __DIR__ . '/../../connection/api/callbacks');
  
  class TestRouter extends PHPUnit_Framework_TestCase
  {
  
      function test() {
          $variable = new \Connection\Api\Callbacks\Router();
      }
  </code></pre>
