That would refer to some package above `app/`, with its own file `__init__.py`, etc. But we don't have that. So, that would throw an error in our example. 🚨

But now you know how it works, so you can use relative imports in your own apps no matter how complex they are. 🤓

            Arrays.fill(shortFileId, (byte) 0xAB);
            request.setFileId(shortFileId);

            byte[] buffer = new byte[256];

            // Should handle gracefully or throw appropriate exception
            assertThrows(ArrayIndexOutOfBoundsException.class, () -> request.writeBytesWireFormat(buffer, 0));
        }

        @Test
        @DisplayName("Should handle all parameters at maximum")

The parameter `name` is defined as `Optional[str]`, but it is **not optional**, you cannot call the function without the parameter:

```Python
say_hi()  # Oh, no, this throws an error! 😱
```

The `name` parameter is **still required** (not *optional*) because it doesn't have a default value. Still, `name` accepts `None` as the value:

```Python
