### Plus loin avec la documentation API alternative

Et maintenant, rendez-vous sur <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a>.

* La documentation alternative reflétera également le nouveau paramètre de requête et le nouveau corps :

# Install to local repository
mvn install
```

### Testing
```bash
# Run all tests (JUnit 4 based)
mvn test

# Run specific test class
mvn test -Dtest=SpecificTest

# Alternative test runner
mvn surefire:test
```

### Code Quality
```bash
# Generate code coverage reports
mvn jacoco:report

# License header validation
mvn apache-rat:check

        Cell a = as[i];
        if (a != null) sum += a.value;
      }
    }
    return sum;
  }

    // TODO(lukes): assert that the logs are full of errors

In einigen Fällen möchten Sie möglicherweise die von den Klassen `Request` und `APIRoute` verwendete Logik überschreiben.

Das kann insbesondere eine gute Alternative zur Logik in einer Middleware sein.

Wenn Sie beispielsweise den <abbr title="Anfragekörper">Requestbody</abbr> lesen oder manipulieren möchten, bevor er von Ihrer Anwendung verarbeitet wird.

It is imported/included directly into FastAPI so that you can import it from `fastapi` and avoid accidentally importing the alternative `BackgroundTask` (without the `s` at the end) from `starlette.background`.
