Unit Testing & Mock Objects - El Forum - 02-23-2009

Hi all,
Has anybody tried writing a test case in CI using mock objects ??.
I have integrated simpletest with CI thanks to the CI wiki but the examples provided aren't sufficeint enough coz they are not dealing with controllers.
If i want to test my controller den should i directly create a mock object of my controller or is there any other approach.

It seems nobody has tried it out yet...anyways i am able to test my model using SimpleTest but without using Mock object. Will try to find a way to do it with mock object too...and will post soon.

The way CI loads itself makes it difficult to create a mock object for database.. :-(.
But if anybody finds a better way post on this thread

Apparently, your answer can be found in chapter 8 of CodeIgniter for Rapid PHP Application Development. http://blogs.linux.ie/kenguest/2008/04/10/book-review-codeigniter-for-rapid-php-application-development/

hi again, i read the book but it just mentions about mock objects for database but nothing relevant is provided....it talks about test data and nothing else. I searched a lot but till now no break through. :-(

Can you post an example of what you have so far? I was in to TDD many years ago. I've probably forgotten most of it, but who knows?

i am developing a demo forum application.
I have following models : ForumTopic, ForumComment....
I want to unit test ForumComment.
Following is my ForumComment model:
Code:
<?php
class ForumComment extends Model
{
var $commentid = null;
var $topicid = null;
var $commenttext = null;
var $userid = null;
var $commentdate = null;
function ForumComment()
{
parent::Model();
}
function getComments($topicid){
$this->db->where('tpid',$topicid);
$data = $this->db->get('comment');
return $data;
}
/**
* Method to persist data into database
*/
function save()
{
$dbarray= array('commtext'=>$this->commenttext,
'commdate'=>$this->commentdate,
'userid'=>$this->userid,
'tpid'=>$this->topicid
);
$this->db->insert('comment',$dbarray);
}
}Following is my unit test case which i was able to create ..its my first unit test case.
Code:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
class ForumCommentModelTest extends UnitTestCase{
var $CI;
function __construct(){
$this->UnitTestCase('Testing Login Functionality');
}
function setUp(){
$this->CI = &get;_instance();
$this->CI->load->model('ForumComment','forum');
}
function tearDown(){}
function testForumComment_getComments(){
$this->CI->forum->ForumComment();
$result = $this->CI->forum->getComments(1);
$result=$result->num_rows();
$this->assertEqual($result,2);
}
}
?>But i have auto loaded the database for the test case to execute. But i want to mock my database but i cant figure out the way to create one.

I'm so confused. That may as well be written in Russian... I guess I can't remember as much as I'd hoped. Sorry...
