CakePHP 3: tests for controller - cakephp

Question

I'm writing tests for a controller in a plugin (Assets plugin).
This is the controller:
namespace Assets\Controller;
use Cake\Controller\Controller;
class AssetsController extends Controller
{
public function asset($filename, $type)
{
$this->response->type($type);
$this->response->file(ASSETS . DS . $filename);
return $this->response;
}
}
As you can see, it only sends an asset files.
This is the route:
Router::plugin('Assets', ['path' => '/assets'], function ($routes) {
$routes->connect(
'/:type/:filename',
['controller' => 'Assets', 'action' => 'asset'],
[
'type' => '(css|js)',
'filename' => '[a-z0-9]+\.(css|js)',
'pass' => ['filename', 'type'],
]
);
});
And this is the test class:
namespace Assets\Test\TestCase\Controller;
use Assets\Utility\AssetsCreator;
use Cake\TestSuite\IntegrationTestCase;
class AssetsControllerTest extends IntegrationTestCase
{
public function testAsset()
{
//This is the filename
$filename = sprintf('%s.%s', AssetsCreator::css('test'), 'css');
$this->get(sprintf('/assets/css/%s', $filename));
$this->assertResponseOk();
}
}
Running the test, however, this exception is generated (full test here):
1) Assets\Test\TestCase\Controller\AssetsControllerTest::testAsset
Cake\Routing\Exception\MissingControllerException: Controller class could not be found. in /home/mirko/Libs/Plugins/Assets/vendor/cakephp/cakephp/src/Http/ControllerFactory.php:91
I do not think is a problem of broken, because the same exception is generated by doing so:
$url = \Cake\Routing\Router::url([
'controller' => 'Assets',
'action' => 'asset',
'plugin' => 'Assets',
'type' => 'css',
'filename' => $filename,
]);
$this->get($url);
Where am I doing wrong? Thanks.

Solved! On my tests' bootstrap, I missed:
DispatcherFactory::add('Routing');
DispatcherFactory::add('ControllerFactory');
Now it works.
