Stumped with unit testing (mock objects and properties)

[Atealtha]

I did a lot of research on lastcraft.com but still could not find a solution.

Here is the gist of my class:

class model {

var $dao; //data access
var $result; //database result object

function model(&$dao) { $this->dao =& $dao; }
function getInfo() { $this->result =& $this->dao->getInfo(); }

} 

Now, I am testing a page controller that uses this model. I easily made a server stub for the dao (which returns another server stub). However when I make a mock object:

Mock::generate('model');
$model =& new Mockmodel($this); 

I just don't know how to make $model->result point to an object. I first just used the class itself until I realised I want to test a callCount for $model.

Also: because it is a mock, I get this error:
Fatal error: Call to a member function on a non-object in /.../lib/class.artcontroller.php on line 41

which is

$model =& new MockModel($this); 

But I think this is because I could not set the property.

So the question is, how can I set my mock $model->result as a reference to one of my server stubs?

iirc, this came up once before and the answer was just to do it.

Something like:

$model =& new MockModel($this);
//some model returns or expectations
$result =& new MockResult($this);
//some result returns or expectations
$model->result =& $result;

$page->run($model);

$result->tally();
$model->tally();

Ended up making a few extra test cases but got rid of one server stub. This will do fine thanks.

Wouldn't sth. like the following work?

Mock::generate('Dao');
 $model =& new MockModel($this);
 $result =& new MockResult($this);
 $dao =& new MockDao($this);
 $dao->setReturnRefernce('getInfo', $result);
 $dao->expectCallCount('getInfo', 1);
$page->run($model);

$result->tally();
$model->tally();
$dao->tally();
