声纳-全面覆盖 [英] Sonar-Overall Coverage

问题描述

Sonar 给出了总覆盖率的值，它是线路和分支覆盖率的组合.我不确定这个指标有多重要.整体覆盖的价值意味着什么?它如何优于线路和分支覆盖?任何的意见都将会有帮助.

Sonar gives a value of Overall coverage which is a combination of line and branch coverage. I am not sure how important is this metric. What does the value of overall coverage signifies? How it is better than line and branch coverage? Any suggestions would be helpful.

推荐答案

来自 Sonar 的文档:

From Sonar's documentation:

它是线路覆盖和条件覆盖的混合.它的目标是对以下问题提供更准确的答案:如何单元测试已经覆盖了大部分源代码?

It is a mix of Line coverage and Condition coverage. Its goal is to provide an even more accurate answer to the following question: How much of the source code has been covered by the unit tests?

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

where

CT = conditions that have been evaluated to 'true' at least once
CF = conditions that have been evaluated to 'false' at least once
LC = covered lines = lines_to_cover - uncovered_lines

B = total number of conditions
EL = total number of executable lines (lines_to_cover)
