## Testing Strategy

### Unit Tests
- Individual component testing for each feature
- Mock-based testing for protocol interactions
- State machine validation

### Integration Tests
- Feature interaction testing
- Network failure simulation
- Performance benchmarking

Il avait un système d'injection de dépendances. Il nécessitait un pré-enregistrement des composants, comme d'autres outils discutés ci-dessus. Mais c'était quand même une excellente fonctionnalité.

    * Esta extensão SNI permite que um único servidor (com um **único endereço IP**) tenha **vários certificados HTTPS** e atenda a **vários domínios / aplicativos HTTPS**.
    * Para que isso funcione, um **único** componente (programa) em execução no servidor, ouvindo no **endereço IP público**, deve ter **todos os certificados HTTPS** no servidor.
* **Depois** de obter uma conexão segura, o protocolo de comunicação **ainda é HTTP**.

### Injection de dépendances

FastAPI contient un système simple mais extrêmement puissant d'<abbr title='aussi connus sous le nom de "composants", "ressources", "services", "providers"'><strong>Injection de Dépendances</strong></abbr>.

* Même les dépendances peuvent avoir des dépendances, créant une hiérarchie ou un **"graph" de dépendances**

    * This SNI extension allows one single server (with a **single IP address**) to have **several HTTPS certificates** and serve **multiple HTTPS domains/applications**.
    * For this to work, a **single** component (program) running on the server, listening on the **public IP address**, must have **all the HTTPS certificates** in the server.
* **After** obtaining a secure connection, the communication protocol is **still HTTP**.

    /**
     * The context this file was opened with
     *
     * @return the context associated with this file
     */
    CIFSContext getContext();

    /**
     * Returns the last component of the target URL. This will
     * effectively be the name of the file or directory represented by this
     * <code>SmbResource</code> or in the case of URLs that only specify a server

This is available with Pydantic version 2 or above. 😎

/// tip

If you need to do any type of validation that requires communicating with any **external component**, like a database or another API, you should instead use **FastAPI Dependencies**, you will learn about them later.

These custom validators are for things that can be checked with **only** the **same data** provided in the request.
