## Architecture

### Module Structure

```
fess-crawler-parent/
├── fess-crawler/              # Core framework
├── fess-crawler-lasta/        # LastaFlute DI integration
└── fess-crawler-opensearch/   # OpenSearch backend
```

### Key Design Patterns

**Factory**: `CrawlerClientFactory`, `ExtractorFactory` - protocol/format-specific component selection

        if (Constants.EXECUTE_TYPE_CRAWLER.equalsIgnoreCase(executeType)) {
            ptList.add(Constants.PROCESS_TYPE_REPLACE);
        } else {

# Tests Asíncronos { #async-tests }

Ya has visto cómo probar tus aplicaciones de **FastAPI** usando el `TestClient` proporcionado. Hasta ahora, solo has visto cómo escribir tests sincrónicos, sin usar funciones `async`.

Vamos a revisar esos conceptos de despliegue de antes:

* Seguridad - HTTPS
* Ejecución al inicio
* Reinicios
* **Replicación (el número de procesos en ejecución)**
* Memoria
* Pasos previos antes de empezar

Hasta este punto, con todos los tutoriales en la documentación, probablemente has estado ejecutando un **programa de servidor**, por ejemplo, usando el comando `fastapi`, que ejecuta Uvicorn, corriendo un **solo proceso**.
