```

## 测试分类

### 1. 单元测试 (Unit Tests)

测试单个组件的隔离行为，不依赖外部服务。

**目录**: `tests/unit/`

**运行命令**:
```bash
npm run test:unit
```

**覆盖范围**:
- 领域实体 (Domain Entities)
- 值对象 (Value Objects)
- 领域服务 (Domain Services)
- 应用层处理器 (Application Handlers)
- 数据映射器 (Data Mappers)

### 2. 集成测试 (Integration Tests)

测试多个组件之间的交互，使用模拟的外部依赖。

**目录**: `tests/integration/`

**运行命令**:
```bash
npm run test:integration
```

**覆盖范围**:
- 仓储实现 (Repository Implementations)
- 控制器 (Controllers)
- 事件发布器 (Event Publishers)

### 3. 端到端测试 (E2E Tests)

测试完整的 API 流程，模拟真实的客户端请求。

**目录**: `tests/e2e/`

**运行命令**:
```bash
npm run test:e2e
```

**覆盖范围**:
- API 端点
- 认证流程
- 错误处理
- 完整的请求/响应周期

## 测试配置

### Jest 配置文件

#### 基础配置 (`tests/jest.config.js`)

  moduleFileExtensions: ['js', 'json', 'ts'],
  rootDir: '..',
  testEnvironment: 'node',

process.env.KAFKA_ENABLED = 'false';

// 增加异步操作超时

## 手动测试指南

### 1. 使用 cURL 测试

```bash
# 1. 健康检查
curl -X GET http://localhost:3006/api/v1/mpc-party/health

# 2. 获取 JWT Token（从身份服务获取或手动生成）
TOKEN="eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."

# 3. 测试 Keygen 参与
curl -X POST http://localhost:3006/api/v1/mpc-party/keygen/participate \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "sessionId": "550e8400-e29b-41d4-a716-446655440000",
    "partyId": "user123-server",
    "joinToken": "join-token-abc123",
    "shareType": "wallet",
    "userId": "user-id-123"
  }'

# 4. 列出分片
curl -X GET "http://localhost:3006/api/v1/mpc-party/shares?page=1&limit=10" \
  -H "Authorization: Bearer $TOKEN"

# 5. 获取分片信息
curl -X GET http://localhost:3006/api/v1/mpc-party/shares/share_xxx \
  -H "Authorization: Bearer $TOKEN"
```

### 2. 使用 Swagger UI

1. 启动开发服务器：
   ```bash
   npm run start:dev
   ```

2. 访问 Swagger UI：
   ```
   http://localhost:3006/api/docs
   ```

3. 点击 "Authorize" 按钮，输入 JWT Token

4. 测试各个端点

### 3. 使用 Postman

1. 导入 API 集合（如果有提供）

2. 设置环境变量：
   - `BASE_URL`: `http://localhost:3006/api/v1`
   - `TOKEN`: JWT Token

3. 按顺序执行请求：
   - 健康检查
   - Keygen 参与
   - 列出分片
   - 获取分片详情

## 测试覆盖率

### 运行覆盖率报告

```bash
npm run test:cov
```

### 覆盖率目标

| 指标 | 目标 | 当前 |
|------|------|------|
| 语句覆盖率 | > 80% | - |
| 分支覆盖率 | > 70% | - |
| 函数覆盖率 | > 80% | - |
| 行覆盖率 | > 80% | - |

### 覆盖率报告输出

报告生成在 `coverage/` 目录下，包含：
- `coverage/lcov-report/index.html` - HTML 报告
- `coverage/lcov.info` - LCOV 格式报告

---

## CI/CD 集成

### GitHub Actions 示例

```yaml
# .github/workflows/test.yml
name: Tests

on:
  push:
    branches: [main, develop]
  pull_request:
    branches: [main]

jobs:
  test:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v3

      - name: Setup Node.js
        uses: actions/setup-node@v3
        with:
          node-version: '18'
          cache: 'npm'

      - name: Install dependencies
        run: npm ci

      - name: Generate Prisma Client
        run: npx prisma generate

      - name: Run unit tests
        run: npm run test:unit

      - name: Run integration tests
        run: npm run test:integration

      - name: Run e2e tests
        run: npm run test:e2e

      - name: Upload coverage
        uses: codecov/codecov-action@v3
        with:
          files: ./coverage/lcov.info
```

---

## 最佳实践

### 1. 测试命名规范

```typescript
describe('ComponentName', () => {
  describe('methodName', () => {
    it('should [expected behavior] when [condition]', () => {
      // ...
    });
  });
});
```

### 2. AAA 模式

```typescript
it('should save share successfully', async () => {
  // Arrange - 准备测试数据
  const share = createMockShare();
  prismaService.partyShare.create.mockResolvedValue(share);

  // Act - 执行被测方法
  await repository.save(share);

  // Assert - 验证结果
  expect(prismaService.partyShare.create).toHaveBeenCalled();
});
```

### 3. 模拟最佳实践

- 只模拟外部依赖，不模拟被测代码
- 使用 `jest.fn()` 创建模拟函数
- 使用 `mockResolvedValue` 和 `mockRejectedValue` 处理异步
- 在 `beforeEach` 中重置模拟

### 4. 避免的反模式

- 测试实现细节而非行为
- 过度模拟
- 测试间相互依赖
- 测试中使用硬编码的时间等待

---

## 故障排除

### 常见问题

1. **测试超时**
   - 增加 Jest 超时时间
   - 检查异步操作是否正确等待

2. **模拟不生效**
   - 确保模拟在测试之前设置
   - 检查依赖注入的 token 是否正确

3. **类型错误**
   - 确保 TypeScript 配置正确
   - 检查 `tsconfig.json` 中的 `paths` 映射

4. **环境变量问题**
   - 确保 `tests/setup.ts` 正确设置环境变量
   - 检查 `jest.config.js` 中的 `setupFilesAfterEnv`
