/**
|
* IoT 网关子设备 CoAP 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>网关设备转发子设备请求时，Token 使用子设备自己的信息。
|
*
|
* <p>使用步骤：
|
* <ol>
|
* <li>启动 yudao-module-iot-gateway 服务（CoAP 端口 5683）</li>
|
* <li>确保子设备已通过 {@link IotGatewayDeviceCoapProtocolIntegrationTest#testTopoAdd()} 绑定到网关</li>
|
* <li>运行 {@link #testAuth()} 获取子设备 token，将返回的 token 粘贴到 {@link #TOKEN} 常量</li>
|
* <li>运行以下测试方法：
|
* <ul>
|
* <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>
