* Aplicar regras de segurança, autenticação, papéis de usuários, etc.
* E muitas outras coisas...

Tudo isso, enquanto minimizamos a repetição de código.

## Primeiros passos { #first-steps }

Vamos ver um exemplo simples. Tão simples que não será muito útil, por enquanto.

Mas dessa forma podemos focar em como o sistema de **Injeção de Dependência** funciona.

    file.createNewFile();
    
    // Monitor for witness notifications
    TestWitnessListener listener = new TestWitnessListener();
    
    // Simulate cluster failover (would require test environment setup)
    // ... trigger server failover ...
    
    // Verify that witness notification was received and handled
    assertTrue(listener.waitForNotification(30000));  // 30 second timeout
