CakePHP 3.0 vendor class not found -


i'm adding external class cake 3.0 app putting /vendor/name folder , requiring component this: 

require_once( $_server['document_root'].'/project/vendor/external/testclass.php');

but when try getinstance(); of class - error 

class 'app\controller\component\test_class' not found

i calling component (thus \controller\component).

what i'm doing wrong?

cakephp 3.0 uses namespaces. use proper namespace vendor class or if it's not using namespaces prefix class name backslash when using it.

e.g. $object = new \test_class();.
