...and have the code for the tests just like before.

## Testing: extended example

Now let's extend this example and add more details to see how to test different parts.

### Extended **FastAPI** app file

Let's continue with the same file structure as before:

```

├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
