CakePHP: calling testAction to a json-returning me

问题:

What am I missing here? Here is my controller code:

public function calculate() {
    $this->set(array(
        "route" => array("A" => 1, "B" => 2),
        "_serialize" => array("route")
    ));

    return;
}

Here is a line from my routes.php file:

Router::parseExtensions();

Here is my test code:

    $result = $this->testAction("/itinerary/calculate.json", array(
        "method" => "POST", 
        "return" => "contents"
    ));

This code throws

MissingViewException: View file "C:\xampp\htdocs\fiver\app\View\Itinerary\calculate.ctp" is missing.

I am obviously missing something here. Please help. Another test for another controller with JSON works just fine

Got it. CakePHP requires the RequestHandler component to be explicitly added to the controller for the extensions to work. I've added this line, it started to work

public $components = array('RequestHandler');

If you dont have/want a view for your controller you can simply add

$this->autoRender = false;

// EDIT: Only working if you dont want an output but thats not the case
