使用 Cobertura 和 Jacoco 运行代码覆盖率

我在获取 Maven 插件项目（使用调用程序插件进行集成测试）的 Sonar 中的集成测试和单元测试的代码覆盖率报告时遇到了一些问题。

我无法使用默认的 Jacoco 覆盖率工具进行单元测试，因为这些工具使用 Powermock，这会导致使用该工具的类的覆盖率为 0%。另一方面，如果不使用 Jacoco，我无法找到可靠的方法来获取基于 Groovy 的集成测试的结果。

所以我需要的是 Cobertura 生成单元测试报告，Jacoco 生成集成测试报告，Sonar 能够读取批次。

我尝试使用这里的例子https://github.com/Godin/sonar-experiments/tree/master/jacoco-examples/maven-invoker-plugin-example https://github.com/Godin/sonar-experiments/tree/master/jacoco-examples/maven-invoker-plugin-example但消除了与测试阶段绑定的执行，但随后我在声纳中得到了​​“-”的单元测试覆盖率。我认为原因是为了让这种方法发挥作用，我需要将 Jacoco 指定为 Sonar 的核心覆盖工具。

有什么办法解决这个问题吗？我的 pom.xml 如下：

由于您已将声纳配置为

 <sonar.dynamicAnalysis>reuseReports</sonar.dynamicAnalysis>
 <sonar.jacoco.itReportPath>
     ${project.basedir}/target/jacoco-t.exec
 </sonar.jacoco.itReportPath>

这意味着您正在告诉 Sonarreuse现有报告来自sonar.jacoco.itReportPath。如果没有现有报告，则没有任何覆盖范围。

就我而言，我使用 Cobertura 并重用其报告Maven 站点生成，使用以下配置属性：

<sonar.java.coveragePlugin>cobertura</sonar.java.coveragePlugin>
<sonar.dynamicAnalysis>reuseReports</sonar.dynamicAnalysis>
<sonar.surefire.reportsPath>
    ${project.build.directory}/surefire-reports
</sonar.surefire.reportsPath>
<sonar.cobertura.reportPath>
    ${project.build.directory}/site/cobertura/coverage.xml
</sonar.cobertura.reportPath>

我可以使用以下命令来重用：

mvn clean install site sonar:sonar

我可以使用以下命令重现您的问题：

mvn clean install sonar:sonar

覆盖率为0%。由于目前还没有报告报告路径.

然后请确保有一个名为“jacoco-t.exec”如执行声纳之前指定的那样。

由于我不熟悉 JaCoCo，也不知道哪个 Maven 阶段生成报告文件，所以我建议执行如下命令：

mvn clean test sonar:sonar

or

mvn clean install sonar:sonar

或者和我的一样

mvn clean install site sonar:sonar

我希望这会有所帮助。
