白盒测试 使用 git log 发现代码变动中因开发粗心导致的问题

qianxing for 点点点 · August 28, 2018 · 1067 hits

原理

当开发提交代码行数小于特定阈值(比如阈值为5行),表明代码中因开发粗心、无单元测试用例导致的简单bug。

命令

git log --pretty=format:"%h %cd %an %s" --date=format:"%Y-%m-%d %H:%M" --shortstat

示例

  1. 示例项目:Jacoco

  2. git log记录

$ git log --pretty=format:"%h %cd %an %s" --date=format:"%Y-%m-%d %H:%M" --shortstat master

特别说明

本文仅使用jacoco项目作为示例,jacoco的代码质量是非常高的,我举例可能不太恰当。但是在项目测试过程中可以根据开发修改bug变更代码行数确定问题是否由于开发粗心、单元测试未覆盖导致的问题。
