+
+## 🚀 运行测试
+
+### 基本命令
+
+```bash
+# 运行所有测试（watch 模式）
+npm run test
+
+# 运行所有测试（单次运行）
+npm run test:run
+
+# 打开测试 UI 界面
+npm run test:ui
+
+# 生成覆盖率报告
+npm run test:coverage
+```
+
+### 运行特定测试
+
+```bash
+# 运行单个测试文件
+npx vitest tests/unit/composables/taskRow/useTaskRowState.spec.ts
+
+# 运行匹配模式的测试
+npx vitest --grep "计时器"
+
+# 运行特定目录的测试
+npx vitest tests/unit/
+```
+
+## 📊 覆盖率目标
+
+| 指标 | 目标 | 说明 |
+|------|------|------|
+| Statements | ≥ 80% | 语句覆盖率 |
+| Branches | ≥ 75% | 分支覆盖率 |
+| Functions | ≥ 80% | 函数覆盖率 |
+| Lines | ≥ 80% | 行覆盖率 |
+
+查看覆盖率报告：
+```bash
+npm run test:coverage
+# 报告生成在 coverage/ 目录
+# 打开 coverage/index.html 查看详细报告
+```
+
+## 🔧 测试工具
+
+### Fixtures (测试数据工厂)
+
+#### tasks.ts
+提供10种预配置的任务数据生成器：
+- `createTask()` - 基础任务
+- `createParentTask()` - 父任务（带子任务）
+- `createChildTask()` - 子任务
+- `createMilestone()` - 里程碑任务
+- `createTaskWithPredecessor()` - 带前置任务
+- `createTimerTask()` - 正在计时的任务
+- `createOvertimeTask()` - 超时任务
+- `createOverdueTask()` - 逾期任务
+- `createReadonlyTask()` - 只读任务
+- `createCustomTask()` - 自定义属性任务
+
+示例：
+```typescript
+import { createTask, createParentTask } from 'tests/fixtures/tasks'
+
+const task = createTask({ name: 'My Task', progress: 50 })
+const parent = createParentTask({ id: 1, children: [task] })
+```
+
+#### columns.ts
+提供列配置生成器：
+- `createNameColumn()` - 名称列
+- `createPredecessorColumn()` - 前置任务列
+- `createAssigneeColumn()` - 负责人列
+- `createStartDateColumn()` - 开始日期列
+- `createEndDateColumn()` - 结束日期列
+- `createProgressColumn()` - 进度列
+- `createDefaultColumns()` - 默认列配置列表
+
+### Helpers (测试工具函数)
+
+#### mount.ts
+- `mountComponent()` - 挂载 Vue 组件
+- `flushPromises()` - 等待所有 Promise 完成
+- `sleep(ms)` - 延迟执行
+- `triggerMouseEvent()` - 触发鼠标事件
+- `getComputed()` - 获取组件 computed 值
+- `hasClass()` - 检查元素类名
+- `getStyle()` - 获取元素样式
+
+## 📝 编写测试指南
+
+### 1. 单元测试示例
+
+```typescript
+import { describe, it, expect } from 'vitest'
+import { ref } from 'vue'
+import { useTaskRowState } from '@/composables/...'
+import { createTask } from '../../../fixtures/tasks'
+
+describe('useTaskRowState', () => {
+  it('应该正确计算缩进', () => {
+    const task = ref(createTask())
+    const level = ref(2)
+    const { taskState } = useTaskRowState(task, level)
+
+    expect(taskState.value.indent).toBe('50px') // 10 + 2*20
+  })
+})
+```
+
+### 2. 组件测试示例
+
+```typescript
+import { describe, it, expect } from 'vitest'
+import { mount } from '@vue/test-utils'
+import TaskRow from '@/components/TaskList/taskRow/TaskRow.vue'
+import { createTask } from '../../fixtures/tasks'
+import { createDefaultColumns } from '../../fixtures/columns'
+
+describe('TaskRow', () => {
+  it('应该渲染任务名称', () => {
+    const wrapper = mount(TaskRow, {
+      props: {
+        task: createTask({ name: 'Test Task' }),
+        level: 0,
+        columns: createDefaultColumns(),
+      },
+    })
+
+    expect(wrapper.text()).toContain('Test Task')
+  })
+})
+```
+
+## 🐛 调试测试
+
+### 使用 Vitest UI
+
+```bash
+npm run test:ui
+```
+
+浏览器会自动打开，提供：
+- 实时测试运行状态
+- 测试代码高亮
+- 错误堆栈追踪
+- 覆盖率可视化
+
+### 调试单个测试
+
+在测试文件中添加 `.only`：
+```typescript
+it.only('应该测试某个功能', () => {
+  // 只运行这个测试
+})
+```
+
+### 查看详细输出
+
+```bash
+npx vitest --reporter=verbose
+```
+
+## ⚠️ 常见问题
+
+### Q: 测试失败显示 "Cannot find module '@/...'"
+A: 确保 `vitest.config.ts` 中配置了正确的路径别名。
+
+### Q: 组件测试中 slot 不显示
+A: 检查 slot 语法，确保使用 `slots: { 'slot-name': () => '...' }`。
+
+### Q: 计时器测试不稳定
+A: 使用 `vi.useFakeTimers()` 和 `vi.advanceTimersByTime()` 控制时间。
+
+### Q: 覆盖率未达标
+A: 运行 `npm run test:coverage`，打开 HTML 报告查看未覆盖代码。

+
+## 🎯 待扩展测试
+
+以下功能建议增加测试覆盖：
+- [ ] TaskRowBadges 组件（徽章显示）
+- [ ] TaskRowCollapseButton 组件（折叠按钮）
+- [ ] TaskRowIcon 组件（任务图标，特别是里程碑无发光效果）
+- [ ] TaskRowNameContent 组件（名称内容）
+- [ ] 集成测试（TaskList 整体交互）
+- [ ] 快照测试（组件输出稳定性）
