Good day. I have a controller method for yii 1. I want to write a unit test for it on phpunit. When testing the method, I do not want the request dataset to be saved to the database through the RainbowVideoWeb model. RainbowVideoWeb -- ActiveRecord model. I do not understand how I can replace the RainbowVideoWeb model with something that does not interact with the database. I need help

 public function actionIndex()

 try 
 $this->layout = '';
 header('Content-type: application/json');
 Yii::log("RAINBOW: " . serialize(Yii::app()->request->getRestParams()));

 $ticketVariant = Yii::app()->request->getPost('ticketVariant');
 $barcode = Yii::app()->request->getPost('ticketCode');
 $stream = Yii::app()->request->getPost('stream');
 $downloadMp4 = Yii::app()->request->getPost('downloadMp4');
 $downloadAvi = Yii::app()->request->getPost('downloadAvi');
 $requestId = Yii::app()->request->getPost('id');

 $rainbowVideo = new RainbowVideoWeb;
 $rainbowVideo->created_at = null;
 $rainbowVideo->ticket_variant = $ticketVariant;
 $rainbowVideo->barcode = $barcode;
 $rainbowVideo->stream = $stream;
 $rainbowVideo->download_mp4 = $downloadMp4;
 $rainbowVideo->download_avi = $downloadAvi;
 $rainbowVideo->request_id = $requestId;

 if ($rainbowVideo->save()) 
 echo json_encode(['status' => 'ok']);
 else 
 $errors = $rainbowVideo->getErrors();
 throw new Exception('Validation Errors. ' . print_r($errors, true));
 

 Yii::app()->end();

 catch (Exception $e) 
 Yii::log("RAINBOW error. " . $e->getMessage(), CLogger::LEVEL_ERROR);
 echo json_encode(['status' => 'error']);
