SecurityComponent black-holing my controller test case

Question

Here's my UsersController test case:

<?php
App::uses('UsersController', 'Controller');

class TestUsersController extends UsersController {

    public $autoRender = false;

    public function redirect($url, $status = null, $exit = true) {
        $this->redirectUrl = $url;
    }

    public function render($action = null, $layout = null, $file = null) {
        $this->renderedAction = $action;
    }

    public function _stop($status = 0) {
        $this->stopped = $status;
    }
}

class UsersControllerTestCase extends ControllerTestCase {

    public $fixtures = array('app.user');

    public function setUp() {
        parent::setUp();
        $this->Users = new TestUsersController();
        $this->Users->constructClasses();
    }

    public function tearDown() {
        unset($this->Users);

        parent::tearDown();
    }

    public function testAdminSearchStudents() {
        $data = array('User' => array('search' => 'Ipsum'));
        $result = $this->testAction('/admin', array('return' => 'vars', 'method' => 'post', 'data' => $data));
        $this->assertCount(1, $result['users']);
    }

}

There's nothing special about my UsersController, but it uses the SecurityComponent (inherited from AppController).

And when I run the tests, i get the infamous:

The request has been black-holed Test case: UsersControllerTestCase(testAdminSearchStudents)

I think it's because i'm forging a POST request without the CSRF token and referal?

What should I do to make this work without removing the Security component from my Controller?

I'm not sure if this will help, but here's the important part of the stack trace:

I solved the problem mocking the the SecurityComponent::_validatePost method:

$this->Users = $this->generate('Users', array(
    'components' => array(
        'Security' => array('_validatePost'),
    )
));
