### Running Tests with Coverage

```bash
mvn clean jacoco:prepare-agent test jacoco:report
```

Coverage reports are generated in `target/site/jacoco/`.

Sin embargo, si usas el comando `pip install fastapi`, el paquete `python-multipart` no se incluye por defecto.

Para instalarlo manualmente, asegúrate de crear un [entorno virtual](../../virtual-environments.md){.internal-link target=_blank}, activarlo, y luego instalarlo con:

```console
$ pip install python-multipart
