Test Coverage

分析和提升代码测试覆盖率。

When to Invoke

  • •评估测试完整性
  • •发现测试缺口
  • •CI/CD 门禁检查
  • •发布前验证
  • •持续改进

Input Format

yaml
project_path: "./src"
coverage_tool: "coverage.py"
target_coverage: 0.85

Output Format

yaml
coverage_report:
  overall:
    line_coverage: 0.82
    branch_coverage: 0.75
    function_coverage: 0.90
  by_module:

      line_coverage: 0.95
      status: "good"
    - name: "utils"
      line_coverage: 0.45

Examples

Example 1: Python 项目覆盖率

Input: Django Web 应用

Output:

  • •视图层覆盖率分析
  • •模型层测试缺口
  • •异常处理覆盖情况
  • •测试优先级建议

Example 2: C 项目覆盖率

Input: 嵌入式固件

Output:

  • •函数覆盖情况
  • •分支覆盖分析
  • •死代码识别
  • •关键路径覆盖建议

Best Practices

  1. •质量优于数量: 100% 覆盖不等于无 bug
  2. •关注边界: 优先覆盖边界和异常
  3. •持续监控: 集成到 CI/CD
  4. •增量检查: 新代码必须覆盖
