CakePHP Simpletest helper

I am new to unit testing, and have been creating new component, controller, and model tests using SimpleTest. I am using CakePHP Test Suite version 1.2.0.0. I am having trouble creating a view for a helper, and the internet has yielded me no assistance. Here is the helper code:

class MyHelper extends AppHelper
{
        var $helpers = array('Session');

        function dostuff()
        {
                $helpervar = $this->Session->read('Data');
                if(empty($helpervar))
                {
                        return;
                }
        }
}

And my test code is here:

App::import('Helper', 'MyHelper');


class MyHelperTest extends CakeTestCase {

        function startTest() {
                $this->MyHelper = new MyHelperHelper();
        }

        function testRender() {
                $this->MyHelper->dostuff();
        }

        function tearDown() {
                unset($this->Controller);
                ClassRegistry::flush();
        }

}

And the error I receive:

Fatal error: Call to a member function read() on a non-object.

I am wondering if I need to create a mock view. I am new to all this so any information would be very much appreciated! Thanks!

The error is caused by the SessionHelper because it is not automagically instantiated. You have to instantiate it manually in the startTest() method:

function startTest() {
    $this->MyHelper = new MyHelper();
    $this->MyHelper->Session = new SessionHelper();
}

After manually creating an instance your class, you have to use constructClasses() to load all your components.

$Class = new ClassController();
$Class->constructClasses();
