声纳中的代码覆盖率和行覆盖率有什么区别 [英] What is the difference between code coverage and line coverage in sonar

问题描述

我知道行覆盖和分支覆盖有什么区别，但是代码覆盖和行覆盖有什么区别?是以前的指令覆盖吗?

I know what the difference is between line and branch coverage, but what is the difference between code coverage and line coverage? Is the former instruction coverage?

推荐答案

Coverage 是一个微妙的 ;-) 线和分支覆盖率的混合.

Coverage is a subtle ;-) mix of the line and the branch coverage.

您可以在我们的指标描述页面上找到公式:

You can find the formula on our metric description page:

coverage = (CT + CF + LC)/(2*B + EL)

where

CT - branches that evaluated to "true" at least once
CF - branches that evaluated to "false" at least once
LC - lines covered (lines_to_cover - uncovered_lines)

B - total number of branches (2*B = conditions_to_cover)
EL - total number of executable lines (lines_to_cover)
