Yukarıdaki uygulama, birden fazla WebSocket bağlantısına mesajları nasıl yönetip broadcast edeceğinizi göstermek için minimal ve basit bir örnektir.

Ancak her şey memory'de, tek bir list içinde yönetildiği için yalnızca process çalıştığı sürece ve yalnızca tek bir process ile çalışacaktır.

        assertNull(sd.getOwnerGroupSid());
    }

    @Test
    @DisplayName("Test constructor with buffer decodes SecurityDescriptor")
    void testConstructorWithBuffer() throws IOException {
        // Prepare minimal valid SecurityDescriptor buffer
        prepareMinimalSecurityDescriptorBuffer(testBuffer, 0, true, true, false);

        SecurityDescriptor sd = new SecurityDescriptor(testBuffer, 0, testBuffer.length);

        when(tree.getConfig()).thenReturn(config);
        when(config.getMaximumBufferSize()).thenReturn(65535);
        when(config.getListSize()).thenReturn(65535);

        // Arrange minimal successful open with one entry
        FileEntry fe1 = mock(FileEntry.class);
        lenient().when(fe1.getName()).thenReturn("x");
        when(fe1.getFileIndex()).thenReturn(1);

        doAnswer(inv -> {

        requestBody.put("included_urls", includedUrls);
        requestBody.put("user_agent", "Mozilla/5.0");
        requestBody.put("depth", 0);
        requestBody.put("max_access_count", 1L); // Already minimal
        requestBody.put("num_of_thread", 1);
        requestBody.put("interval_time", 0); // No delay between requests
        requestBody.put("boost", 100);
        requestBody.put("available", true);

That will raise the `WebSocketDisconnect` exception, and all the other clients will receive a message like:

```
Client #1596980209979 left the chat
```

/// tip

The app above is a minimal and simple example to demonstrate how to handle and broadcast messages to several WebSocket connections.

        DcerpcHandle handle = mock(DcerpcHandle.class);
        LsaPolicyHandle policy = mock(LsaPolicyHandle.class);

        jcifs.SID[] sids = new jcifs.SID[] { sid("S-1-1-0") };

        // Arrange a minimal response with given retval
        doAnswer(inv -> {
            jcifs.dcerpc.msrpc.MsrpcLookupSids rpc = inv.getArgument(0);
            rpc.retval = ret;
            // Provide empty arrays to satisfy code paths

Cela lèvera l'exception `WebSocketDisconnect`, et tous les autres clients recevront un message comme :

```
Client #1596980209979 left the chat
```

/// tip | Astuce

L'application ci-dessus est un exemple minimal et simple pour montrer comment gérer et diffuser des messages à plusieurs connexions WebSocket.

            assertNotNull(fileFsSizeInfo.getFree());
        }

        @ParameterizedTest
        @DisplayName("Should decode various sector and allocation configurations")
        @CsvSource({ "1000, 500, 1, 512", // Minimal sectors per alloc

                "1000, 500, 64, 512", // Large allocation units
                "1000, 500, 8, 4096", // 4K sectors

        requestBody.put("included_urls", includedUrls);
        requestBody.put("user_agent", "Mozilla/5.0");
        requestBody.put("depth", 0);
        requestBody.put("max_access_count", 2L); // Minimal: 1 success + 1 failure
        requestBody.put("num_of_thread", 1);
        requestBody.put("interval_time", 0); // No delay
        requestBody.put("boost", 100);
        requestBody.put("available", true);

    * Objetos JSON (`dict`).
    * array JSON (`list`) definiendo tipos de elementos.
    * Campos de string (`str`), definiendo longitudes mínimas y máximas.
    * Números (`int`, `float`) con valores mínimos y máximos, etc.

* Validación para tipos más exóticos, como:
    * URL.
    * Email.
    * UUID.
    * ...y otros.
