En este caso, es el `str`:

## An app with callbacks { #an-app-with-callbacks }

Let's see all this with an example.

Imagine you develop an app that allows creating invoices.

These invoices will have an `id`, `title` (optional), `customer`, and `total`.

The user of your API (an external developer) will create an invoice in your API with a POST request.

Then your API will (let's imagine):

            nameServiceClient.getNbtByName("NONEXISTENT-FAST-FAIL");
        }, "Should throw UnknownHostException for non-existent NetBIOS name");

        // Verify the exception message indicates name resolution failure
        assertTrue(exception.getMessage().contains("NONEXISTENT") || exception.getMessage().contains("unknown")
