# ==========================================
# GitHub Actions Workflow: Continuous Integration
# ==========================================
#
# 功能：持续集成测试和代码质量检查
#
# 触发条件：
#   - Pull Request 创建或更新
#   - 推送到 main 分支
#
# 工作流程：
#   1. 依赖安装和缓存
#   2. 运行测试套件
#   3. TypeScript 类型检查
#   4. ESLint 代码检查
#   5. 验证构建成功
#
# 目的：
#   - 确保所有代码变更通过质量检查
#   - 在合并前发现潜在问题
#   - 保持代码库健康

    steps:
      # ------------------------------------------
      # 步骤 1: 检出代码
      # ------------------------------------------
      - name: 📥 Checkout repository
        uses: actions/checkout@v4

      # ------------------------------------------
      # 步骤 2: 设置 Node.js
      # ------------------------------------------
      - name: 🔧 Setup Node.js
        uses: actions/setup-node@v4
        with:
          node-version: ${{ env.NODE_VERSION }}
          cache: 'npm'

      # ------------------------------------------
      # 步骤 3: 安装依赖
      # ------------------------------------------
      - name: 📦 Install dependencies
        run: npm ci

      # ------------------------------------------
      # 步骤 4: 运行快速测试（无覆盖率，更快）
      # ------------------------------------------
      - name: 🧪 Run fast tests
        run: npm run test:ci
        continue-on-error: false
        timeout-minutes: 3

      # ------------------------------------------
      # 步骤 5: 上传测试覆盖率
      # ------------------------------------------
      - name: 📊 Upload coverage reports
        uses: actions/upload-artifact@v4
        if: always()
        with:
          name: coverage-report
          path: coverage/
          retention-days: 7

      # ------------------------------------------
      # 步骤 6: TypeScript 类型检查
      # ------------------------------------------
      - name: 🔍 Run type checking
        run: npm run typecheck

      # ------------------------------------------
      # 步骤 7: ESLint 代码检查
      # ------------------------------------------
      - name: 🎨 Run linting
        run: npm run lint

      # ------------------------------------------
      # 步骤 8: 构建验证
      # ------------------------------------------
      - name: 🏗️ Build extension
        run: npm run build

      # ------------------------------------------
      # 步骤 9: 验证构建产物
      # ------------------------------------------
      - name: ✅ Verify build
        run: |
          echo "📋 Verifying build artifacts..."

          # 检查关键文件
          test -f dist/manifest.json || exit 1
          test -f dist/icons/icon16.png || exit 1
          test -f dist/icons/icon48.png || exit 1
          test -f dist/icons/icon128.png || exit 1

          echo "✅ Build verification passed"

      # ------------------------------------------
      # 步骤 10: 总结
      # ------------------------------------------
      - name: 📣 CI Summary
        if: success()
        run: |
          echo "## ✅ CI Checks Completed" >> $GITHUB_STEP_SUMMARY
          echo "" >> $GITHUB_STEP_SUMMARY
          echo "All quality checks passed successfully:" >> $GITHUB_STEP_SUMMARY
          echo "- ✅ Tests passed with coverage" >> $GITHUB_STEP_SUMMARY
          echo "- ✅ Type checking passed" >> $GITHUB_STEP_SUMMARY
