There are some scenarios where you might want to override a dependency during testing.

You don't want the original dependency to run (nor any of the sub-dependencies it might have).

Instead, you want to provide a different dependency that will be used only during tests (possibly only some specific tests), and will provide a value that can be used where the value of the original dependency was used.

### Use cases: external service { #use-cases-external-service }

No quieres que la dependencia original se ejecute (ni ninguna de las sub-dependencias que pueda tener).

En cambio, quieres proporcionar una dependencia diferente que se usará solo durante las pruebas (posiblemente solo algunas pruebas específicas), y que proporcionará un valor que pueda ser usado donde se usó el valor de la dependencia original.

### Casos de uso: servicio externo { #use-cases-external-service }
