CakePHP 2.0 Redirect Testing

I watched a few examples in the cookbook, but I do not understand: http://book.cakephp.org/2.0/en/development/testing.html#a-more-complex-example

How can I check redirection in delete action like this?

public function delete($id = null){         
        $this->Comment->id = $id;
        if (!$this->Comment->exists()) {
            throw new NotFoundException(__('Invalid comment'));
        }
        if ($this->Comment->delete()) {         
            $this->Session->setFlash(__('Comment deleted'));
            return $this->redirect(array('controller' => 'posts', 'action' => 'view', $idPost));
        }
        $this->Session->setFlash(__('Comment was not deleted'));
        return $this->redirect(array('controller' => 'posts', 'action' => 'view', $idPost));        
    }
}

The test stops after redirecting, so it does not even print this echo:

public function testDelete(){       
    $result = $this->testAction("/comments/delete/1");
    echo "this is not printed";
    print_r($this->headers);        
}

Testing your removal action should be relatively the same as testing any other action. Your test case might look something like this.

// notice it extends ControllerTestCase
class PostsControllerTest extends ControllerTestCase {

    function testDelete() {
      $this->testAction('/posts/delete/1');
      $results = $this->headers['Location'];
      // your OP code redirected them to a view, which I assume is wrong
      // because the item would be deleted
      $expected = '/posts/index';
      // check redirect
      $this->assertEquals($results, $expected);

      // check that it was deleted
      $this->Posts->Post->id = 1;
      $this->assertFalse($this->Posts->Post->exists());
    }

}

, . , . , - .

mocks generate ControllerTestCase.

function testDelete() {
  $Posts = $this->generate('Posts', array(
    'components' => array(
      'Email' => array('send'),
      'Session'
    )
  ));
  // set ControllerTestCase to use this mock
  $this->controller = $Posts;

  $this->testAction('/posts/some_action_that_sends_email');
}

PostsController . send() EmailComponent SessionComponent.

, , $idPost - undefined.

- :

public function delete($id = null){         
        $this->Comment->id = $id;
        if (!$this->Comment->exists()) {
            throw new NotFoundException(__('Invalid comment'));
        }
        if ($this->Comment->delete()) {         
            $this->Session->setFlash(__('Comment deleted'));
        } else {
            $this->Session->setFlash(__('Comment was not deleted'));
        }
        $this->redirect(array('controller' => 'posts', 'action' => 'view', $id));        
    }
}

:

public function testDeleteWithSuccess() {
        $Controller = $this->generate('Comments', array(
            'components' => array(
                'Session'
            ),
            'models' => array(
                'Comment' => array('exists')
            )
        ));

        $Controller->Comment->expects($this->once())
            ->method('exists')
            ->will($this->returnValue(true));

        $Controller->Session->expects($this->once())
            ->method('setFlash')
            ->with('Comment deleted');

        $this->testAction("/comments/delete/ID");

        $this->assertEquals($this->headers['Location'], 'http://'. $_SERVER['HTTP_HOST'] . '/posts/view/ID');
    }

An echo is never printed, your delete function always causes a redirect to the end.

Plenix, Isn't that so? Do you delete the comment and pass the comment identifier to the message view controller? So, are you viewing a post or comment by doing this? Any other suggestion?
