CakePHP 3.0 vendor class not found

Question

I'm adding an external class to a cake 3.0 app by putting it to /vendor/name folder and requiring it from a component like this:

require_once( $_SERVER['DOCUMENT_ROOT'].'/project/vendor/external/testClass.php');

But when I try to getInstance(); of a class - I get an error

Class 'App\Controller\Component\Test_Class' not found 

I am calling this from a component (thus the \Controller\Component).

What is it that i'm doing wrong?

CakePHP 3.0 uses namespaces. So use proper namespace for your vendor class or if it's not using namespaces prefix the class name with backslash when using it.

E.g. $object = new \Test_Class();.
