**FastAPI** créera l'objet de type `BackgroundTasks` pour vous et le passera comme paramètre.

## Créer une fonction de tâche

Une fonction à exécuter comme tâche d'arrière-plan est juste une fonction standard qui peut recevoir des paramètres.

Elle peut être une fonction asynchrone (`async def`) ou une fonction normale (`def`), **FastAPI** saura la gérer correctement.

        try {
            crawlJob.execute();
            fail("Should throw JobProcessingException");
        } catch (JobProcessingException e) {
            assertTrue(e.getMessage().contains("Failed to execute a crawl job"));
            assertNotNull(e.getCause());
            assertEquals("Test exception", e.getCause().getMessage());
        }
    }

    // Test execute with JobProcessingException in executeCrawler

### About `__name__ == "__main__"` { #about-name-main }

The main purpose of the `__name__ == "__main__"` is to have some code that is executed when your file is called with:

<div class="termy">

```console
$ python myapp.py
```

</div>

but is not called when another file imports it, like in:

```Python
from myapp import app
```

### Deletar um Hero

Também podemos **deletar** um `Hero`.

### Executar o App

Você pode executar o app:

<div class="termy">

```console
$ fastapi dev main.py
