我需要在Controller中测试add方法，我正在使用cakephp框架和phpunit进行测试，控制器中的方法如下所示：
public function add() {
$this->CategoryProblem->create();
if ($this->CategoryProblem->save($this->request->data)) {
$message = 'Saved';
} else {
$message = 'Error';
}
$this->set(array(
'message' => $message,
'_serialize' => array('message')
));
}
，测试看起来像这样：
public function testAdd() {
$data = array(
'CategoryProblems' => array(
'id' => '15',
'parent_id'=>null,
'modified'=> '',
'deleted'=>'',
'name'=>'raspado',
'description'=>null,
),
);
$this->testAction('/categoryproblems/add',array('data'=> $data ));
$result = $this->_testAction('/categoryproblems.json',array('method'=>'pot','data'=>array(json_decode('message'))));
$this->assertTrue($result,'Saved');
debug($result);
}
当我运行测试时出现此错误：
