$this->fetchRow creates failure in phpunit in Zend framework - zend-framework

Question

I followed Rob Allens ZF 1 Tutorial and wanted to pimp it up with some UnitTesting. But whenever I run the phpunit command, i get the message:
here was 1 failure:
1) IndexControllerTest::testDeleteAction
Failed asserting last controller used <"error"> was "Index"
/path/to/library/Zend/Test/PHPUnit/ControllerTestCase.php:1000
/path/to/tests/application/controllers/IndexControllerTest.php:55
FAILURES!
Tests: 4, Assertions: 9, Failures: 1.
The Action in question is the deleteAction and looks like this:
public function deleteAction() {
if ($this->getRequest()->isPost()) {
$del = $this->getRequest()->getPost('del');
if ($del == 'Yes') {
$id = $this->getRequest()->getPost('id');
$wishes = new Application_Model_DbTable_Wishes();
$wishes->deleteWish($id);
}
$this->_helper->redirector('index');
}
else {
$id = $this->_getParam('id', 0);
$wishes = new Application_Model_DbTable_Wishes();
$this->view->wish = $wishes->getWish($id);
}
}
I tracked the error down to be $wishes>getWish($id); so if i go to that function, that looks like this:
public function getWish($id) {
$id = (int) $id;
$row = $this->fetchRow('id = ' . $id);
if(!$row){
throw new Exception("Could not find row $id");
}
return $row->toArray();
}
it appears the line $row = $this->fetchRow('id = ' . $id); causes the problem. And I can't figure out why. All action work just fine, they do as expected.Any idea how to fix this?
Thanks!

Maybe try using the select() object instead if a plain string:
public function getWish($id) {
$id = (int) $id;
$select = $this->select();
$select->where('id = ?', $id);
$row = $this->fetchRow($select);
if(!$row){
throw new Exception("Could not find row $id");
}
return $row->toArray();
}
This just a wild guess, but who knows. The only thing that looks at all odd is the lack of a placeholder in the query string (?).
FetchRow() does like to work with the select() object, in fact if you pass a string the first thing fetchRow() does is build a select(). So maybe it just doesn't like the string.
