声纳报告的线路和分支覆盖范围不同于Idea、Eclipse、Maven和Jenkins

Question

我所有这些工具都报告了与JaCoCo相同的覆盖率：69%的线路覆盖率和23%的分支覆盖率。

注意：截图已经拍摄了几天，所以它们的值略有不同，但差异是

然而，声纳报告了不同的值:

360.png" width="100%" height="100%" />

Maven项目的结构如下：

< li >主(聚合器) < ul > < li>java模块 js(节点)模块

您可以看到main和java模块报告的覆盖率相同，而js模块没有覆盖率。

我正在使用最新版本的雅各语，哈科专家插件和声纳的Java插件。

以下是来自 mvn 声纳：声纳的相关构建日志片段 - 似乎都按顺序排列：

这是声纳的Java插件中的一个错误吗？我认为，当由不同人员配置的其他3个工具始终显示不同的值时，声纳报告的指标不太可能是正确的。

Answer 1

覆盖率指标似乎已经自我修复。它现在报告正确的值——顺便说一句，我们在同一天将JDK升级到最新的补丁版本（8u92）。

这表明JaCoCo传感器根据JRE无法正常工作，但需要更多的调查。

Answer 2

以下是计算“单元测试覆盖率”度量的方法：

• NUMBER_OF_LINES=行数条件数。
• COVERED_LINES=NUMBER_OF_LINES-（未覆盖的行数未覆盖的条件数。

覆盖率= (100 *覆盖的行数)/行数。
