# 年会互动大屏系统 - 压力测试指南
|
||
|
||
## 快速开始
|
||
|
||
### 1. 安装依赖
|
||
```bash
|
||
cd packages/server
|
||
pnpm add -D artillery @artilleryio/engine-socketio-v3
|
||
```
|
||
|
||
### 2. 确保服务运行
|
||
```bash
|
||
# 根目录启动所有服务
|
||
pnpm dev
|
||
|
||
# 或仅启动服务端
|
||
pnpm dev:server
|
||
```
|
||
|
||
### 3. 运行压测
|
||
```bash
|
||
# 冒烟测试 (快速验证)
|
||
pnpm test:load:smoke
|
||
|
||
# 标准测试
|
||
pnpm test:load
|
||
|
||
# 重压模式 (200并发，对应需求规格书验收标准)
|
||
pnpm test:load:heavy
|
||
|
||
# 脉冲测试 (模拟现场投票热潮)
|
||
pnpm test:load:pulse
|
||
```
|
||
|
||
---
|
||
|
||
## 测试模式说明
|
||
|
||
| 模式 | 命令 | 并发量 | 持续时间 | 用途 |
|
||
|------|------|--------|----------|------|
|
||
| `smoke` | `pnpm test:load:smoke` | 5 | 5s | 快速验证配置 |
|
||
| `standard` | `pnpm test:load` | 50 | 20s | 日常开发测试 |
|
||
| `heavy` | `pnpm test:load:heavy` | 200 | 35s | **验收标准 (150人并发)** |
|
||
| `pulse` | `pnpm test:load:pulse` | 150-200 | 21s | 模拟现场脉冲式投票 |
|
||
|
||
---
|
||
|
||
## 验收标准
|
||
|
||
根据 `年会互动大屏系统需求规格说明书.md`：
|
||
|
||
| 指标 | 目标值 | 检查方式 |
|
||
|------|--------|----------|
|
||
| 并发连接 | 200+ | Artillery 报告 `vusers.session_length` |
|
||
| QPS | > 1000 | 报告 `socketio.emit_rate` |
|
||
| 延迟 P95 | < 500ms | 报告 `socketio.response_time.p95` |
|
||
| 错误率 | < 1% | 报告 `vusers.failed` / `vusers.completed` |
|
||
| Redis 计数 | 准确无丢票 | 对比 Redis 统计与预期投票数 |
|
||
|

|
||
|
||
## 报告输出
|
||
|
||
测试完成后会输出类似以下报告：
|
||
|
||
```
|
||
All VUs finished. Total time: 35 seconds

|
||
## 高级用法
|
||
|
||
### 生成 HTML 报告
|
||
```bash
|
||
npx artillery run packages/server/load-test/vote-load-test.yaml \
|
||
--output report.json && \
|
||
npx artillery report report.json
|
||
```
|
||
|
||
### 指定环境运行
|
||
```bash
|
||
npx artillery run packages/server/load-test/vote-load-test.yaml -e heavy
|
||
```
|
||
|
||
### 调试模式 (查看详细日志)
|
||
```bash
|
||
DEBUG=socketio:* npx artillery run packages/server/load-test/vote-load-test.yaml -e smoke
|
||
```
|
||

|
||
|
||
## 故障排查
|
||
|
||
### 1. 连接失败
|
||
- 检查服务端是否运行在 `localhost:3000`
|
||
- 确认 CORS 配置允许本地访问
|
||
|
||
### 2. 投票被拒绝 (VOTING_CLOSED)
|
||
- 确保导播台已开启投票通道
|
||
- 或临时修改服务端绕过投票状态检查
|
||
|
||
### 3. 性能不达标
|
||
- 检查 Redis 连接是否正常
|
||
- 确认未在调试模式运行
|
||
- 考虑增加 Node.js 内存限制: `NODE_OPTIONS="--max-old-space-size=4096"`
