## Una aplicación con callbacks { #an-app-with-callbacks }

Veamos todo esto con un ejemplo.

Imagina que desarrollas una aplicación que permite crear facturas.

Estas facturas tendrán un `id`, `title` (opcional), `customer` y `total`.

El usuario de tu API (un desarrollador externo) creará una factura en tu API con un request POST.

Luego tu API (imaginemos):

* Enviará la factura a algún cliente del desarrollador externo.

    private DcerpcHandle mockDcerpcHandle;

    // Mocking MsrpcLsarOpenPolicy2 and MsrpcLsarClose is tricky because they are created inside the constructor/method.
    // We need to use ArgumentCaptor or a custom Answer to control their behavior.
    // For now, let's assume we can mock their behavior through the sendrecv method of DcerpcHandle.

    @BeforeEach
    void setUp() {
