 **Cerberus e Validator_raw.py** <br>
 
 Para não criarmos cada validação de entrada manualmente, podemos utilizar o 'Validator' da biblioteca do Cerberus. <br>
 
+----
+**Mock_value** <br>
+
+Para evitar a criação desnecessária de barcodes a cada teste, foi instanciada uma cópia fantasma ou espelho, que atenderá as demandas do teste unitário sem necessariamente criar algo, retornando o valor desejado através do 'mock_value', no trecho de código abaixo. <br>
+```py
+from  unittest.mock import patch
+from src.drivers.barcode_handler import BarcodeHandler
+from .tag_creator_controller import TagCreatorController
+
+@patch.object(BarcodeHandler, 'create_barcode')
+def test_create(mock_create_barcode):
+    mock_value = "image_path"
+    mock_create_barcode.value = mock_value
+    tag_creator_controller = TagCreatorController()
+
+    result = tag_creator_controller.create(mock_value)
+```
