Magento 1.9: How to create order programmatically - magento

Question

I found similar topics, but they are not up to date.
I have to generate around 1000 orders with random products. I found good article about creating orders http://inchoo.net/magento/programmatically-create-order-in-magento/ but it's kinda old and it's not working on version 1.9.
I get following errors:
array (size=5)
0 => string 'Please specify the product's option(s).' (length=39)
1 => string 'Please specify the product's option(s).' (length=39)
2 => string 'Please specify the product's option(s).' (length=39)
3 => string 'Please specify the product's option(s).' (length=39)
4 => string 'Please specify the product's option(s).' (length=39)
#0 E:\xampp\htdocs\magento\app\code\core\Mage\Adminhtml\Model\Sales\Order\Create.php(1631): Mage::throwException('')
#1 E:\xampp\htdocs\magento\app\code\core\Mage\Adminhtml\Model\Sales\Order\Create.php(1523): Mage_Adminhtml_Model_Sales_Order_Create->_validate()
As you can see in my create method I add options to product, so why do I get this errors?
Here is my class
class MyNamespace_MyModule_Model_Generate_Sample {
protected $orderData;
protected $product;
public function run()
{
//$customer is a random customer object
$product = Mage::getModel('catalog/product')->load(342);
$this->product = $product;
$this->orderData = array(
'session' => array(
'customer_id' => $customer->getId(),
'store_id' => Mage::app()->getStore('default')->getId(),
),
'payment' => array(
'method' => 'checkmo',
),
'add_products' =>array(
$product->getId() => array('qty' => 1),
),
