## 💡 如何开发测试用例
### 测试驱动开发TDD流程
遵循 **Red-Green-Refactor** 循环:
```
1. Red → 先写测试,运行失败(红色)
2. Green绿 → 编写最少代码使测试通过(绿色)
3. Refactor重构 → 优化代码,保持测试通过
```
### 测试金字塔
```
/\
/ \ E2E Tests (10%)
/____\ - 慢,昂贵,脆弱
/ \ - 测试关键用户流程
/________\
/ \ Integration Tests (20%)
/____________\ - 测试组件间协作
/______________\ Unit Tests (70%)
- 快,稳定,便宜
- 测试单个函数/组件
```
### 文件命名规范
```bash
src/
├── components/
│ ├── NotificationContainer/
│ │ ├── index.js
│ │ └── __tests__/
│ │ └── NotificationContainer.test.js # ✅ 组件测试
├── services/
│ ├── notificationHistoryService.js
│ └── __tests__/
│ └── notificationHistoryService.test.js # ✅ 服务测试
├── constants/
│ ├── notificationTypes.js
│ └── __tests__/
│ └── notificationTypes.test.js # ✅ 常量测试
└── contexts/
├── NotificationContext.js
└── __tests__/
└── NotificationContext.test.js # ✅ Context 测试
```
### 测试结构AAA 模式)
**Arrange - Act - Assert**
```javascript
test('应该正确添加通知到历史记录', () => {
// Arrange准备- 设置测试数据和环境
const notification = {
id: 'test001',
type: 'announcement',
title: '测试通知',
content: '测试内容',
publishTime: Date.now(),
};
// Act执行- 调用要测试的函数
notificationHistoryService.add(notification);
// Assert断言- 验证结果
const history = notificationHistoryService.getAll();
expect(history).toHaveLength(1);
expect(history[0].title).toBe('测试通知');
});
```
### 测试编写最佳实践
#### 1. 每个测试只测一个功能
**不推荐**(测试多个功能):
```javascript
test('通知系统功能测试', () => {
// 测试添加
service.add(notification);
expect(service.getAll()).toHaveLength(1);
// 测试筛选
expect(service.filter({ type: 'announcement' })).toHaveLength(1);
// 测试删除
service.clear();
expect(service.getAll()).toHaveLength(0);
});
```
**推荐**(拆分成独立测试):
```javascript
test('应该正确添加通知', () => {
service.add(notification);
expect(service.getAll()).toHaveLength(1);
});
test('应该正确筛选通知', () => {
service.add(notification);
expect(service.filter({ type: 'announcement' })).toHaveLength(1);
});
test('应该正确清空通知', () => {
service.add(notification);
service.clear();
expect(service.getAll()).toHaveLength(0);
});
```
#### 2. 使用描述性的测试名称
**不推荐**:
```javascript
test('test 1', () => { ... });
test('works', () => { ... });
```
**推荐**:
```javascript
test('应该在收到新事件时添加到通知列表', () => { ... });
test('应该在紧急通知时不自动关闭', () => { ... });
test('应该在权限被拒绝时不触发浏览器通知', () => { ... });
```
#### 3. 使用 Mock 隔离外部依赖
```javascript
// Mock localStorage
beforeEach(() => {
localStorage.clear();
localStorage.setItem.mockClear();
});
// Mock Audio API
global.Audio = jest.fn().mockImplementation(() => ({
play: jest.fn().mockResolvedValue(undefined),
}));
// Mock Notification API
global.Notification = {
permission: 'granted',
requestPermission: jest.fn().mockResolvedValue('granted'),
};
```
#### 4. 清理测试环境
```javascript
describe('notificationHistoryService', () => {
beforeEach(() => {
// 每个测试前清理
localStorage.clear();
});
afterEach(() => {
// 每个测试后清理(如果需要)
jest.clearAllMocks();
});
test('测试用例', () => { ... });
});
```
### 常见测试模式
#### 模式1: 测试纯函数
```javascript
// src/utils/formatTime.js
export const formatNotificationTime = (timestamp) => {
const diff = Date.now() - timestamp;
if (diff < 60000) return '刚刚';
if (diff < 3600000) return `${Math.floor(diff / 60000)}分钟前`;
return '很久前';
};
// __tests__/formatTime.test.js
describe('formatNotificationTime', () => {
test('应该返回"刚刚"当时间小于1分钟', () => {
const timestamp = Date.now() - 30000; // 30秒前
expect(formatNotificationTime(timestamp)).toBe('刚刚');
});
test('应该返回正确的分钟数', () => {
const timestamp = Date.now() - 120000; // 2分钟前
expect(formatNotificationTime(timestamp)).toBe('2分钟前');
});
});
```
#### 模式2: 测试 React 组件
```javascript
// __tests__/NotificationCard.test.js
import { render, screen, fireEvent } from '@testing-library/react';
import NotificationCard from '../NotificationCard';
describe('NotificationCard', () => {
const mockNotification = {
id: 'test001',
type: 'announcement',
priority: 'important',
title: '测试通知',
content: '测试内容',
};
test('应该渲染通知标题和内容', () => {
render(<NotificationCard notification={mockNotification} />);
expect(screen.getByText('测试通知')).toBeInTheDocument();
expect(screen.getByText('测试内容')).toBeInTheDocument();
});
test('应该在点击关闭按钮时调用 onClose', () => {
const mockOnClose = jest.fn();
render(<NotificationCard notification={mockNotification} onClose={mockOnClose} />);
const closeButton = screen.getByRole('button', { name: /关闭/i });
fireEvent.click(closeButton);
expect(mockOnClose).toHaveBeenCalledWith('test001');
});
});
```
#### 模式3: 测试异步逻辑
```javascript
// __tests__/browserNotificationService.test.js
describe('browserNotificationService', () => {
test('应该在权限授予时显示浏览器通知', async () => {
global.Notification.permission = 'granted';
const mockNotification = { title: '测试', body: '内容' };
await browserNotificationService.show(mockNotification);
// 验证 Notification 构造函数被调用
expect(global.Notification).toHaveBeenCalledWith('测试', expect.any(Object));
});
});
```

## 🚀 如何运行测试用例
### 基础命令
```bash
# 运行所有测试
npm test
# 运行所有测试CI模式运行一次后退出
npm test -- --watchAll=false
# 监视模式(修改文件时自动重新运行)
npm test -- --watch
# 运行特定文件的测试
npm test notificationTypes.test.js
# 运行匹配模式的测试
npm test -- --testNamePattern="应该正确添加通知"
# 生成覆盖率报告
npm test -- --coverage
# 生成覆盖率并在浏览器中查看
npm test -- --coverage && open coverage/lcov-report/index.html
```
### 运行特定测试套件
```bash
# 只运行单元测试
npm test -- --testPathPattern=__tests__
# 只运行集成测试
npm test -- --testPathPattern=integration
# 只运行 E2E 测试
npm test -- --testPathPattern=e2e
```
### 调试测试
#### 方法1: 使用 console.log
```javascript
test('调试示例', () => {
const result = someFunction();
console.log('结果:', result); // 在控制台输出
expect(result).toBe(expected);
});
```
#### 方法2: 使用 VS Code 调试
`.vscode/launch.json` 中添加:
```json
{
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "Jest 当前文件",
"program": "${workspaceFolder}/node_modules/.bin/jest",
"args": [
"${fileBasename}",
"--runInBand",
"--no-cache",
"--watchAll=false"
],
"console": "integratedTerminal",
"internalConsoleOptions": "neverOpen"
}
]
}
```
#### 方法3: 使用 test.only
```javascript
test.only('只运行这个测试', () => {
// 其他测试会被跳过
expect(1 + 1).toBe(2);
});
test('这个测试不会运行', () => {
expect(2 + 2).toBe(4);
});
```
### 持续集成CI/CD
在 GitHub Actions、GitLab CI 等平台中运行测试:
```yaml
# .github/workflows/test.yml
name: Tests
on: [push, pull_request]
jobs:
test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Setup Node.js
uses: actions/setup-node@v2
with:
node-version: '14'
- name: Install dependencies
run: npm install
- name: Run tests
run: npm test -- --watchAll=false --coverage
- name: Upload coverage
uses: codecov/codecov-action@v2
```

## ⚖️ 手动测试 vs 自动化测试
### 自动化测试适用场景
**应该用自动化测试**:
| 场景 | 原因 | 示例 |
|------|------|------|
| 单元逻辑测试 | 快速、稳定、可重复 | 工具函数、数据处理逻辑 |
| 组件渲染测试 | 验证输出是否正确 | 通知卡片是否显示正确内容 |
| API 响应测试 | Mock 数据验证业务逻辑 | Socket 消息处理逻辑 |
| 回归测试 | 防止修改破坏现有功能 | 每次提交前运行全部测试 |
| 边界条件测试 | 覆盖各种输入情况 | 空数据、超长文本、特殊字符 |
**自动化测试覆盖率目标**:
- 业务逻辑层: **80%+**
- 关键服务: **90%+**
- 工具函数: **95%+**
### 手动测试必需场景
**必须用手动测试**:
| 场景 | 原因 | 示例 |
|------|------|------|
| UI/UX 体验 | 自动化测试无法评估"用户感受" | 动画流畅度、视觉美观度、交互自然度 |
| 浏览器兼容性 | 需要在真实浏览器中验证 | Chrome、Edge、Firefox、Safari 表现 |
| 浏览器原生 API | Mock 无法完全模拟真实行为 | Notification API、Audio API、WebSocket |
| 网络环境 | 需要真实网络条件 | 断线重连、高延迟、弱网测试 |
| 用户流程 | 验证完整的用户旅程 | 从打开网站 → 授权 → 接收通知 → 点击跳转 |
| 性能测试 | 需要真实环境数据 | 大量通知时的内存占用、渲染性能 |
| 探索性测试 | 发现意料之外的问题 | 用户可能进行的非预期操作 |
### 对比总结
| | 自动化测试 | 手动测试 |
|--|-----------|---------|
| **速度** | 🚀 快(秒级) | 🐢 慢(分钟级) |
| **成本** | 💰 初期高(编写成本),长期低 | 💰💰 持续高(人力成本) |
| **稳定性** | ✅ 高(可重复) | ⚠️ 低(人为误差) |
| **覆盖面** | 📊 窄(只测定义的场景) | 🌐 广(可探索未知问题) |
| **运行时机** | 🔄 每次提交、CI/CD | 👨‍💻 发布前、重大更新 |
| **适用对象** | 🔧 开发人员 | 👥 测试人员 + 开发人员 |
### 最佳实践:两者结合
```
开发阶段:
1. TDD 开发 → 先写自动化测试
2. 实现功能 → 使测试通过
3. 手动验证 → 检查 UI 和交互
提交前:
1. 运行所有自动化测试 → npm test
2. 快速手动测试 → 关键流程验证
发布前:
1. 完整回归测试 → 自动化测试套件
2. 完整手动测试 → 按手动测试清单逐项验证
3. 跨浏览器测试 → Chrome、Edge、Firefox、Safari
```
### 结论
> **开发了自动化测试用例后,仍然需要手动测试!**
>
> - **自动化测试**:保证**功能正确性**和**代码质量**70-80%覆盖率)
> - **手动测试**:关注**用户体验**和**边缘场景**20-30%
> - **两者互补**:确保系统既稳定又好用
**推荐测试策略**:
```
每次提交: 自动化测试 (100%) + 手动测试 (关键流程)
每周发布: 自动化测试 (100%) + 手动测试 (完整清单)
重大版本: 自动化测试 (100%) + 手动测试 (完整清单) + 外部测试人员
```
