/**
|
* IoT 网关子设备 WebSocket 协议集成测试（手动测试）
|
*
|
* <p>测试场景：子设备（IotProductDeviceTypeEnum 的 SUB 类型）通过网关设备代理上报数据
|
*
|
* <p><b>重要说明：子设备无法直接连接平台，所有请求均由网关设备（Gateway）代为转发。</b>
|
*
|
* <p>使用步骤：
|
* <ol>
|
* <li>启动 yudao-module-iot-gateway 服务（WebSocket 端口 8094）</li>
|
* <li>确保子设备已通过 {@link IotGatewayDeviceWebSocketProtocolIntegrationTest#testTopoAdd()} 绑定到网关</li>
|
* <li>运行以下测试方法：
|
* <ul>
|
* <li>{@link #testAuth()} - 子设备认证</li>
|
* <li>{@link #testPropertyPost()} - 子设备属性上报（由网关代理转发）</li>
|
* <li>{@link #testEventPost()} - 子设备事件上报（由网关代理转发）</li>
|
* </ul>
|
* </li>
|
* </ol>
|
*
|
* <p>注意：WebSocket 协议是有状态的长连接，认证成功后同一连接上的后续请求无需再携带认证信息
