### Usa el atributo `app.dependency_overrides` { #use-the-app-dependency-overrides-attribute }

Para estos casos, tu aplicación **FastAPI** tiene un atributo `app.dependency_overrides`, es un simple `dict`.

Para sobrescribir una dependencia para las pruebas, colocas como clave la dependencia original (una función), y como valor, tu dependencia para sobreescribir (otra función).

### Use the `app.dependency_overrides` attribute { #use-the-app-dependency-overrides-attribute }

For these cases, your **FastAPI** application has an attribute `app.dependency_overrides`, it is a simple `dict`.

To override a dependency for testing, you put as a key the original dependency (a function), and as the value, your dependency override (another function).

The `TestClient` is based on <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, and luckily, we can use it directly to test the API.

## Example { #example }

For a simple example, let's consider a file structure similar to the one described in [Bigger Applications](../tutorial/bigger-applications.md){.internal-link target=_blank} and [Testing](../tutorial/testing.md){.internal-link target=_blank}:

```

    }
  }

  // fails in Maven with 64-bit JDK: https://github.com/google/guava/issues/1568

  // A simple type whose .toString() will return the same value each time, but without maintaining
  // a strong reference to that value.

    return result;
