/**
 * WebSocket OpenAPI控制器测试
 * 
 * 功能描述：
 * - 测试WebSocket OpenAPI文档功能
 * - 验证REST API端点响应
 * - 测试WebSocket消息格式文档
 * - 验证API文档结构
 * 
 * 测试范围：
 * - 连接信息API测试
 * - 消息格式API测试
 * - 架构信息API测试
 * - 响应结构验证
 * 
 * 最近修改：
 * - 2026-01-12: Bug修复 - 修复测试用例中的方法名，只测试实际存在的REST端点 (修改者: moyin)
 * - 2026-01-12: 代码规范优化 - 创建测试文件，确保WebSocket OpenAPI控制器功能的测试覆盖 (修改者: moyin)
