## Worker性能测试
191+
192+
`vue-styled-components`使用Web Worker进行复杂样式计算，以避免阻塞主线程。我们提供了性能测试工具来比较Worker和主线程在不同场景下的性能差异。
193+
194+
### 运行测试
195+
196+
```bash
197+
# 在浏览器中运行可视化性能测试
198+
npm run test:worker
199+
200+
# 在命令行中运行性能测试
201+
npm run benchmark:worker
202+
```
203+
204+
### 测试代码结构
205+
206+
性能测试相关的代码位于项目根目录的`worker-benchmark`文件夹中：
207+
208+
- `worker-benchmark.ts` - 核心的基准测试实现
209+
- `worker-performance.ts` - 单元测试形式的性能测试
210+
- `api.ts` - 提供用于基准测试和可视化的API
211+
- `worker-demo.html` - 带有图表显示的可视化测试页面
212+
213+
### 测试场景
214+
215+
测试覆盖以下几个场景：
216+
217+
1. **简单样式计算** - 少量简单的CSS规则
218+
2. **复杂样式计算** - 多个复杂的CSS规则
219+
3. **大量样式计算** - 大量的CSS规则，模拟大型应用场景
220+
4. **混合样式计算** - 混合简单和复杂的CSS规则
221+
5. **阈值边界测试** - 测试接近复杂度阈值的场景
222+
6. **Worker不可用场景** - 模拟Worker不可用时的回退机制
223+
224+
### 性能优化
225+
226+
根据测试结果，我们实现了智能的样式计算策略：
227+
228+
- 对于简单样式（规则数量少于阈值），直接在主线程中计算，避免Worker创建和通信开销
229+
- 对于复杂样式，使用Worker异步计算，避免阻塞主线程
230+
- 当Worker不可用时，自动回退到主线程计算
231+
232+
这种策略在保持良好性能的同时，确保了样式计算的可靠性和兼容性。
