# Vitest Configuration (Vue 3)

## 最小配置

```js
// vitest.config.ts
import { defineConfig } from 'vitest/config'
import vue from '@vitejs/plugin-vue'

export default defineConfig({
  plugins: [vue()],
  test: {
    environment: 'jsdom',
    globals: true,
    setupFiles: ['./tests/setup.ts'],
    coverage: {
      reporter: ['text', 'html'],
      include: ['src/**/*.{js,vue}']
    }
  }
})
```

## setup 示例

```js
// tests/setup.ts
import { config } from '@vue/test-utils'

config.global.mocks = {
  $t: (k) => k
}
```

## 建议

- 单元测试优先针对 `.utils.ts` 与 composables
- 组件测试只覆盖关键交互与边界状态
- 覆盖率门槛与业务关键性一致，不盲目追求 100%
