# AIOps 验证计划 — 全模块回归测试

> 基于 ROADMAP P0-P3 模块定义，每个模块开发前先写验证用例，实现后必须跑通。
> 最后更新: 2026-06-25

## 通用验证流程

```bash
# 0. 环境准备
cd /srv/aiops

# 1. 重建后端
docker-compose up -d --build backend
sleep 10 && docker ps --format '{{.Names}} {{.Status}}' | grep aiops-backend

# 2. 获取 JWT Token（用 Python 避免 shell 引号问题）
python3 -c "
import urllib.request, json
login_data = json.dumps({'username': 'admin', 'password': '123456'}).encode()
req = urllib.request.Request('http://127.0.0.1:8080/api/v1/auth/login', data=login_data, method='POST')
req.add_header('Content-Type', 'application/json')
resp = urllib.request.urlopen(req)
print(json.loads(resp.read())['data']['token'])
" > /tmp/aiops_token
TOKEN=$(cat /tmp/aiops_token)

# 3. 验证后端健康
curl -s http://127.0.0.1:8080/health | python3 -m json.tool

# 4. 前端构建
cd frontend && npm run build 2>&1 | tail -3
```

### 通过标准
- [x] U1: `/ws/stats` 返回 total + by_type + by_user + by_type_user
- [x] U2: `/ws/connections` 返回连接列表（含 uptime_sec/connect_time/type/user）
- [x] U3: 连接打开→注册→关闭→注销全流程正确
- [x] U4: 多连接并发注册正常（5 连接同时）
- [x] 心跳机制: ping=30s + pong_handler + read_deadline=60s
- [x] `go build` 零错误，17/17 回归测试通过
- [x] 6 个 WebSocket handler 共享统一 WSManager（webshell/kubectl/podexec/audit/metrics/pipeline）
