+# 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%
