Based on PHP 5 exception mechanism.

• WebRoot/protected/views/system
• yii/framework/views

Handling Errors Using an Action

First Method

						
							return array(
							    ......
							    'components'=>array(
							        'errorHandler'=>array(
							            'errorAction'=>'site/error',
							        ),
							    ),
							);
						
					

Second Method

						
							public function actionError()
							{
							    if($error=Yii::app()->errorHandler->error)
							        $this->render('error', $error);
							}
						
					

Unit Testing

Yii testing Framework is built on top of PHPUnit.

• CTestCase
• CDbTestCase

						
						class CommentTest extends CDbTestCase
						{
						    public $fixtures=array(
						        'posts'=>'Post',
						        'comments'=>'Comment',
