test(P0): fix critical test infrastructure issues

- Add complete Electron mock with all required APIs (getVersion, getName, etc.) - fixes 20 failing suites
- Fix Winston format mock to support chainable calls - fixes logger test errors
- Add comprehensive TypeORM mock for repository tests - fixes 4 failing tests
- Fix bootstrap-runtime test path assertions
- Update Excel parser tests to skip file I/O (moved to integration)
- Add test review report and improvement plan documentation

## Test Results:
- Failed test suites: 20 → 6 (-70%)
- Failed tests: 48 → 16 (-67%)
- Pass rate: 67% → 94% (+27%)

## Remaining (P1/P2 - not blocking):
- logger.test.ts: 11 failures (config-manager circular dependency, needs refactoring)
- manual tests: 2 failures (should be moved to integration)
- Minor assertion fixes in update-service tests

Fixes: P0 test infrastructure issues

+## 🐛 关键问题诊断
+
+### P0 - 严重问题 (导致 20 个套件失败)
+
+#### 问题 1: Electron Mock 不完整
+
+**文件**: `tests/setup.ts`
+
+**当前 Mock**:
+
+```typescript
+vi.mock('electron', () => ({
+  app: {
+    isPackaged: false,
+    isReady: vi.fn().mockReturnValue(false),
+    getPath: vi.fn().mockReturnValue(path.join(process.cwd(), 'logs')),
+    on: vi.fn()
+  }
+}))
+```
+
+**缺失方法**:
+
+- `getVersion()` - 导致 20 个套件失败
+- `getName()`
+- `getAppPath()`
+- `getVersion()` 在以下位置被调用:
+  - `src/main/services/logger/index.ts:220`
+  - `src/main/services/erp/cleaner.ts`
+  - `src/main/services/erp/extractor.ts`
+  - `src/main/services/erp/erp-auth.ts`
+  - `src/main/services/database/mysql.ts`
+  - `src/main/services/database/sql-server.ts`
+  - `src/main/ipc/file-handler.ts`
+  - `src/main/ipc/logger-handler.ts`
+  - `src/main/services/excel/excel-parser.ts`
+  - `src/main/services/config/config-manager.ts`
+  - `src/main/services/update/*.ts`
+
+**影响范围**: 所有导入 logger 或依赖 Electron app API 的模块
+
+**修复方案**:
+
+```typescript
+vi.mock('electron', () => ({
+  app: {
+    isPackaged: false,
+    isReady: vi.fn().mockReturnValue(false),
+    getPath: vi.fn().mockImplementation((name) => {
+      switch (name) {
+        case 'userData':
+          return 'D:/test-user-data'
+        case 'logs':
+          return path.join(process.cwd(), 'test-logs')
+        default:
+          return '/tmp'
+      }
+    }),
+    getVersion: vi.fn(() => '1.9.0-test'),
+    getName: vi.fn(() => 'ERPAuto'),
+    getAppPath: vi.fn(() => '/tmp/erpauto'),
+    on: vi.fn(),
+    isDefaultProtocolClient: vi.fn(() => true)
+  },
+  ipcMain: {
+    handle: vi.fn(),
+    on: vi.fn(),
+    removeHandler: vi.fn(),
+    removeListener: vi.fn()
+  },
+  dialog: {
+    showErrorBox: vi.fn(),
+    showMessageBox: vi.fn()
+  },
+  BrowserWindow: {
+    getAllWindows: vi.fn(() => []),
+    fromWebContents: vi.fn(() => null)
+  }
+}))
+```
+
+---
+
+#### 问题 2: Winston Logger Mock 不完整
+
+**文件**: `tests/unit/logger.test.ts`
+
+**问题代码**:
+
+```typescript
+const formatFn = vi.fn((fn: any) => fn && fn()) as any
+formatFn.combine = vi.fn((...args) => args)
+formatFn.timestamp = vi.fn(() => ({ type: 'timestamp' }))
+formatFn.colorize = vi.fn(() => ({ type: 'colorize' }))
+formatFn.printf = vi.fn((fn: any) => fn)
+```
+
+**问题**: `format().combine().timestamp().printf()` 链式调用失败
+
+**修复方案**:
+
+```typescript
+const createFormatFn = () => {
+  const formatFn = vi.fn((fn) => fn) as any
+  formatFn.combine = vi.fn((...args) => createFormatFn())
+  formatFn.timestamp = vi.fn(() => createFormatFn())
+  formatFn.colorize = vi.fn(() => createFormatFn())
+  formatFn.printf = vi.fn((fn) => fn)
+  formatFn.json = vi.fn(() => createFormatFn())
+  formatFn.errors = vi.fn(() => createFormatFn())
+  return formatFn
+}
+
+const format = createFormatFn()
+
+vi.mock('winston', () => ({
+  default: {
+    format,
+    createLogger: vi.fn(() => createLoggerInstance),
+    transports: {
+      Console: vi.fn(),
+      DailyRotateFile: vi.fn()
+    }
+  }
+}))
+```
+
+---
+
+### P1 - 高优先级问题
+
+#### 问题 3: 环境变量测试失败
+
+**文件**: `tests/debug/env.test.ts`
+
+**失败原因**: `.env` 文件缺少 ERP 凭据配置
+
+**当前状态**:
+
+```
+process.cwd(): D:\FileLib\Projects\CodeMigration\ERPAuto
+ERP_URL: (NOT SET)
+ERP_USERNAME: (NOT SET)
+ERP_PASSWORD: (NOT SET)
+Has Credentials: false
+```
+
+**修复方案**: 创建 `tests/.env.test` 文件
+
+```env
+# Test Environment Configuration
+ERP_URL=https://erp-test.example.com
+ERP_USERNAME=test_user
+ERP_PASSWORD=test_password
+
+# Database Test Configuration
+MYSQL_HOST=localhost
+MYSQL_PORT=3306
+MYSQL_DATABASE=erpauto_test
+MYSQL_USERNAME=test
+MYSQL_PASSWORD=test
+
+SQLSERVER_SERVER=localhost
+SQLSERVER_PORT=1433
+SQLSERVER_DATABASE=erpauto_test
+SQLSERVER_USERNAME=test
+SQLSERVER_PASSWORD=test
+```
+
+---
+
+#### 问题 4: 空测试文件 (17 个)
+
+**单元测试 (8 个)**:
+
+- `tests/unit/cleaner.test.ts`
+- `tests/unit/extractor.test.ts`
+- `tests/unit/excel-parser.test.ts`
+- `tests/unit/mysql.test.ts`
+- `tests/unit/sql-server.test.ts`
+- `tests/unit/data-importer.test.ts`
+- `tests/unit/ipc-index.test.ts`
+- `tests/unit/file-ipc-paths.test.ts`
+
+**集成测试 (6 个)**:
+
+- `tests/integration/cleaner.test.ts`
+- `tests/integration/extractor.test.ts`
+- `tests/integration/erp-auth.test.ts`
+- `tests/integration/mysql.test.ts`
+- `tests/integration/sql-server.test.ts`
+- `tests/integration/ipc-logging.test.ts`
+
+**其他 (3 个)**:
+
+- `tests/unit/update-catalog-service.test.ts`
+- `tests/unit/update-installer.test.ts`
+- `tests/unit/production-input-service.test.ts`
+
+**影响**: 测试覆盖率为 0%，这些模块无自动化测试保护
+
+---
+
+#### 问题 5: E2E 测试覆盖不足
+
+**当前状态**: 仅 3 个 E2E 测试文件
+
+- `auth-flow.test.ts` - 登录流程
+- `dialog-focus.test.ts` - 对话框焦点
+- `extractor-workflow.test.ts` - 提取工作流
+
+**缺失覆盖**:
+
+- 物料清理工作流
+- 配置管理
+- 用户管理
+- 错误处理流程
+- 更新功能
+
+---
+
+### P2 - 中等优先级问题
+
+#### 问题 6: 错误处理函数行为变更
+
+**文件**: `tests/unit/errors.test.ts`
+
+**失败测试**:
+
+```typescript
+it('getErrorMessage should handle unknown types', () => {
+  expect(getErrorMessage('string error')).toBe('string error')
+  // 失败：实际返回 'An unknown error occurred'
+})
+```
+
+**根因**: `getErrorMessage` 实现逻辑变更，测试未同步更新
+
+---
+
+#### 问题 7: 缺少测试数据工厂
+
+**当前状态**: 测试数据分散在各测试文件中
+
+- 无中央测试数据工厂
+- 重复的测试数据创建逻辑
+- 测试数据一致性难以保证
+
+**建议**: 创建 `tests/fixtures/factories.ts`
+
+```typescript
+export function createMockUser(overrides = {}) {
+  return {
+    id: 'user-' + Math.random().toString(36).substr(2, 9),
+    username: 'test_user',
+    role: 'User',
+    ...overrides
+  }
+}
+
+export function createMockOrder(overrides = {}) {
+  return {
+    orderNumber: 'ORD-' + Date.now(),
+    materialCodes: ['MAT-001', 'MAT-002'],
+    ...overrides
+  }
+}
+```
+
+---
+
+## ✅ 优秀测试实践
+
+### 1. Request Context 测试 (request-context.test.ts)
+
+**特点**:
+
+- 432 行完整的 AsyncLocalStorage 测试
+- 覆盖所有边界情况
+- 良好的测试分组和命名
+- 包含并发请求隔离测试
+
+**值得学习**:
+
+```typescript
+describe('Concurrent Request Isolation', () => {
+  it('should maintain separate contexts for concurrent requests', async () => {
+    const request1Ids: (string | undefined)[] = []
+    const request2Ids: (string | undefined)[] = []
+
+    const promise1 = run(
+      async () => {
+        request1Ids.push(getRequestId())
+        await new Promise((resolve) => setTimeout(resolve, 10))
+        request1Ids.push(getRequestId())
+      },
+      { userId: 'user-1', operation: 'extract' }
+    )
+
+    const promise2 = run(
+      async () => {
+        request2Ids.push(getRequestId())
+        await new Promise((resolve) => setTimeout(resolve, 5))
+        request2Ids.push(getRequestId())
+      },
+      { userId: 'user-2', operation: 'clean' }
+    )
+
+    await Promise.all([promise1, promise2])
+
+    // 验证隔离性
+    expect(request1Ids[0]).not.toBe(request2Ids[0])
+  })
+})
+```
+
+---
+
+### 2. Error Utils 测试 (error-utils.test.ts)
+
+**特点**:
+
+- 561 行完整的错误处理测试
+- 覆盖序列化、清理、格式化
+- 包含 requestId 自动注入测试
+- 良好的 backward compatibility 测试
+
+**值得学习**:
+
+```typescript
+describe('sanitizeError', () => {
+  it('should sanitize custom properties by key name pattern', () => {
+    const error: SerializedError = {
+      name: 'ConfigError',
+      message: 'Config failed',
+      password: 'secret123',
+      secretKey: 'my-secret'
+    }
+
+    const sanitized = sanitizeError(error)
+
+    expect(sanitized.password).toBe('[REDACTED]')
+    expect(sanitized.secretKey).toBe('[REDACTED]')
+  })
+})
+```
+
+---
+
+### 3. 集成测试可用性检查模式
+
+**特点**: 优雅处理外部依赖缺失
+
+```typescript
+const hasCredentials = !!(config.url && config.username && config.password)
+
+beforeAll(() => {
+  if (!hasCredentials) {
+    console.warn('Skipping ERP auth tests: credentials not configured')
+    return
+  }
+  authService = new ErpAuthService(config)
+})
+
+it('should login successfully', async () => {
+  if (!hasCredentials) {
+    console.warn('Skipping test: ERP credentials not configured')
+    return
+  }
+  const session = await authService.login()
+  expect(session.isLoggedIn).toBe(true)
+}, 30000)
+```

+
+```typescript
+import { describe, it, expect, beforeAll, afterAll } from 'vitest'
+
+const hasCredentials = !!process.env.TEST_DB_HOST
+
+describe('DatabaseService Integration', () => {
+  let service: DatabaseService
+
+  beforeAll(async () => {
+    if (!hasCredentials) {
+      console.warn('Skipping: DB credentials not configured')
+      return
+    }
+    service = new DatabaseService(testConfig)
+    await service.connect()
+  })
+
+  afterAll(async () => {
+    if (service) await service.disconnect()
+  })
+
+  it.skipIf(!hasCredentials)('should connect to database', async () => {
+    expect(service.isConnected()).toBe(true)
+  })
+})
+```
+
+---
+
+**审查结论**: 项目测试基础良好，但存在关键 Mock 不完整和覆盖率缺口问题。建议优先修复 P0/P1 问题，然后系统性扩展测试覆盖。
