+# MCPHub Coding Instructions
+
+## Project Overview
+
+MCPHub is a TypeScript/Node.js MCP server management hub that provides unified access through HTTP endpoints.
+
+**Core Components:**
+
+- **Backend**: Express.js + TypeScript + ESM (`src/server.ts`)
+- **Frontend**: React/Vite + Tailwind CSS (`frontend/`)
+- **MCP Integration**: Connects multiple MCP servers (`src/services/mcpService.ts`)
+
+## Development Environment
+
+```bash
+pnpm install
+pnpm dev           # Start both backend and frontend
+pnpm backend:dev   # Backend only
+pnpm frontend:dev  # Frontend only
+```
+
+## Project Conventions
+
+### File Structure
+
+- `src/services/` - Core business logic
+- `src/controllers/` - HTTP request handlers
+- `src/types/index.ts` - TypeScript type definitions
+- `src/config/index.ts` - Configuration management
+
+### Key Notes
+
+- Use ESM modules: Import with `.js` extensions, not `.ts`
+- Configuration file: `mcp_settings.json`
+- Endpoint formats: `/mcp/{group|server}` and `/mcp/$smart`
+- All code comments must be written in English
+- Frontend uses i18n with resource files in `locales/` folder
+- Server-side code should use appropriate abstraction layers for extensibility and replaceability
+
+## Development Process
+
+- For complex features, implement step by step and wait for confirmation before proceeding to the next step
+- After implementing features, no separate summary documentation is needed - update README.md and README.zh.md as appropriate
+
+### Development Entry Points
+
+- **MCP Servers**: Modify `src/services/mcpService.ts`
+- **API Endpoints**: Add routes in `src/routes/`, controllers in `src/controllers/`
+- **Frontend Features**: Start from `frontend/src/pages/`
+- **Testing**: Follow existing patterns in `tests/`

+# 测试框架和自动化测试实现报告
+
+## 概述
+
+本项目已成功引入现代化的测试框架和自动化测试流程。实现了基于Jest的测试环境，支持TypeScript、ES模块，并包含完整的CI/CD配置。
+
+## 已实现的功能
+
+### 1. 测试框架配置
+
+- **Jest配置**: 使用`jest.config.cjs`配置文件，支持ES模块和TypeScript
+- **覆盖率报告**: 配置了代码覆盖率收集和报告
+- **测试环境**: 支持Node.js环境的单元测试和集成测试
+- **模块映射**: 配置了路径别名支持
+
+### 2. 测试工具和辅助函数
+
+创建了完善的测试工具库 (`tests/utils/testHelpers.ts`):
+
+- **认证工具**: JWT token生成和管理
+- **HTTP测试**: Supertest集成用于API测试
+- **数据生成**: 测试数据工厂函数
+- **响应断言**: 自定义API响应验证器
+- **环境管理**: 测试环境变量配置
+
+### 3. 测试用例实现
+
+已实现的测试场景：
+
+#### 基础配置测试 (`tests/basic.test.ts`)
+- Jest配置验证
+- 异步操作支持测试
+- 自定义匹配器验证
+
+#### 认证逻辑测试 (`tests/auth.logic.test.ts`)
+- 用户登录逻辑
+- 密码验证
+- JWT生成和验证
+- 错误处理场景
+- 用户数据验证
+
+#### 路径工具测试 (`tests/utils/pathLogic.test.ts`)
+- 配置文件路径解析
+- 环境变量处理
+- 文件系统操作
+- 错误处理和边界条件
+- 跨平台路径处理
+
+### 4. CI/CD配置
+
+GitHub Actions配置 (`.github/workflows/ci.yml`):
+
+- **多Node.js版本支持**: 18.x和20.x
+- **自动化测试流程**: 
+  - 代码检查 (ESLint)
+  - 类型检查 (TypeScript)
+  - 单元测试执行
+  - 覆盖率报告
+- **构建验证**: 应用构建和产物验证
+- **集成测试**: 包含数据库环境的集成测试
+
+### 5. 测试脚本
+
+在`package.json`中添加的测试命令：
+
+```json
+{
+  "test": "jest",
+  "test:watch": "jest --watch",
+  "test:coverage": "jest --coverage",
+  "test:verbose": "jest --verbose",
+  "test:ci": "jest --ci --coverage --watchAll=false"
+}
+```
+
+## 测试结果
+
+当前测试统计：
+- **测试套件**: 3个
+- **测试用例**: 19个
+- **通过率**: 100%
+- **执行时间**: ~15秒
+
+### 测试覆盖的功能模块
+
+1. **认证系统**: 用户登录、JWT处理、密码验证
+2. **配置管理**: 文件路径解析、环境变量处理
+3. **基础设施**: Jest配置、测试工具验证
+
+## 技术特点
+
+### 现代化特性
+
+- **ES模块支持**: 完全支持ES2022模块语法
+- **TypeScript集成**: 类型安全的测试编写
+- **异步测试**: Promise和async/await支持
+- **模拟系统**: Jest mock功能的深度使用
+- **参数化测试**: 数据驱动的测试用例
+
+### 最佳实践
+
+- **测试隔离**: 每个测试用例独立运行
+- **Mock管理**: 统一的mock清理和重置
+- **错误处理**: 完整的错误场景测试
+- **边界测试**: 输入验证和边界条件覆盖
+- **文档化**: 清晰的测试用例命名和描述
+
+## 后续扩展计划
+
+### 短期目标
+
+1. **API测试**: 为REST API端点添加集成测试
+2. **数据库测试**: 添加数据模型和存储层测试
+3. **中间件测试**: 认证和权限中间件测试
+4. **服务层测试**: 核心业务逻辑测试
+
+### 中期目标
+
+1. **端到端测试**: 使用Playwright或Cypress
+2. **性能测试**: API响应时间和负载测试
+3. **安全测试**: 输入验证和安全漏洞测试
+4. **契约测试**: API契约验证
+
+### 长期目标
+
+1. **测试数据管理**: 测试数据库和fixture管理
+2. **视觉回归测试**: UI组件的视觉测试
+3. **监控集成**: 生产环境测试监控
+4. **自动化测试报告**: 详细的测试报告和趋势分析
+
+## 开发指南
+
+### 添加新测试用例
+
+1. 在`tests/`目录下创建对应的测试文件
+2. 使用`testHelpers.ts`中的工具函数
+3. 遵循命名约定: `*.test.ts`或`*.spec.ts`
+4. 确保测试用例具有清晰的描述和断言
+
+### 运行测试
+
+```bash
+# 运行所有测试
+pnpm test
+
+# 监听模式
+pnpm test:watch
+
+# 生成覆盖率报告
+pnpm test:coverage
+
+# CI模式运行
+pnpm test:ci
+```
+
+### Mock最佳实践
+
+- 在`beforeEach`中清理所有mock
+- 使用具体的mock实现而不是空函数
+- 验证mock被正确调用
+- 保持mock的一致性和可维护性
+
+## 结论
+
+本项目已成功建立了完整的现代化测试框架，具备以下优势：
+
+1. **高度可扩展**: 易于添加新的测试用例和测试类型
+2. **开发友好**: 丰富的工具函数和清晰的结构
+3. **CI/CD就绪**: 完整的自动化流水线配置
+4. **质量保证**: 代码覆盖率和持续测试验证
+
+这个测试框架为项目的持续发展和质量保证提供了坚实的基础，支持敏捷开发和持续集成的最佳实践。
