Integration Testing

集成测试

Test interactions between multiple components, modules, or services.

测试多个组件、模块或服务之间的交互。

When to use me

适用场景

Use this skill when:

Components have been unit tested and need to work together
Testing API contracts between services
Verifying database interactions work correctly
Checking third-party service integrations
Ensuring microservices communicate properly
Validating data flows through the system

在以下场景使用本技能：

组件已完成单元测试，需要验证协同工作情况
测试服务之间的API契约
验证数据库交互是否正常工作
检查第三方服务集成
确保微服务通信正常
验证数据在系统中的流转

What I do

功能说明

Identify integration points between components
Set up test environments with real or test databases
Configure service connections and API endpoints
Test data flow between integrated components
Verify error handling across component boundaries
Check contract compliance between services
Validate end-to-end workflows without UI

识别组件之间的集成点
使用真实或测试数据库搭建测试环境
配置服务连接和API端点
测试集成组件之间的数据流转
验证跨组件边界的错误处理
检查服务之间的契约合规性
无需UI即可验证端到端工作流

Examples

Run integration tests

npm run test:integration # Node.js integration tests pytest tests/integration/ # Python integration tests go test -tags=integration # Go integration tests

Test specific integrations

npm run test:integration -- --grep "database" pytest tests/integration/test_api_client.py

Run with test containers for external services

docker-compose -f docker-compose.test.yml up --abort-on-container-exit

undefined

docker-compose -f docker-compose.test.yml up --abort-on-container-exit

Integration Test Results:
──────────────────────────────
✅ API Service ↔ Database
  ✓ User data persists correctly
  ✓ Transaction rollback on failure

❌ Payment Service ↔ Banking API
  ✗ Authentication token refresh fails
  ✗ Currency conversion rate mismatch

⚠️ Email Service ↔ Queue
  ⚠️ Message retention period too short

Summary: 8 passed, 2 failed, 1 warning

Notes

注意事项

Integration tests are slower than unit tests
Use test databases or in-memory databases
Mock only external third-party services
Test happy paths and error scenarios
Clean up test data between tests
Consider using test containers for external dependencies
Focus on contract testing for microservices

集成测试比单元测试慢
使用测试数据库或内存数据库
仅模拟外部第三方服务
测试正常流程和错误场景
在测试之间清理测试数据
考虑为外部依赖使用测试容器
微服务重点关注契约测试
