Within `tests/2_functional-tests.js` , alter the `'send {surname: "da Verrazzano"}'` test (`// #4 `):
Send the following JSON response as a payload to the `/travellers` route:

}
```

Check for the following, within a `request.end` callback:
1. `status`
2. `type`
3. `body.name`
4. `body.surname`
Follow the assertion order above - we rely on it. Be sure to remove `assert.fail()` , once complete.
