Также у Вас может быть файл `test_main.py` содержащий тесты. Можно разместить тестовый файл и файл приложения в одной директории (в директориях для Python-кода желательно размещать и файл `__init__.py`):

``` hl_lines="5"
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

```

In the file `main.py` you have your **FastAPI** app:


```Python
{!../../../docs_src/app_testing/main.py!}
```

### Testing file

Then you could have a file `test_main.py` with your tests. It could live on the same Python package (the same directory with a `__init__.py` file):

``` hl_lines="5"
