Ant JaCoCo和声纳是如何工作的？
我试图通过Sonar ut ant JaCoCo运行测试示例了解JaCoCo和Sonar是如何协同工作的：Ant JaCoCo和声纳是如何工作的？,ant,sonarqube,jacoco,Ant,Sonarqube,Jacoco,我试图通过Sonar ut ant JaCoCo运行测试示例了解JaCoCo和Sonar是如何协同工作的： JaCoCo在任务本身期间使用。执行时，JaCoCo使用覆盖率信息插入测试中使用的类文件。这将生成一个jacaco.exec文件。然后使用该文件生成代码覆盖率报告 通常有一个任务，它接受jacoco.exec文件并生成文本文件、HTML页面或包含覆盖信息的XML文件。这可能是声纳用来分析的 当然，很难不看到build.xml文件的工作原理。build.xml在示例中：因此，如果我理解正确，
JaCoCo在
jacaco.execjacoco.exec当然，很难不看到
build.xmljacoco.execjacoco.execant测试期间完全计算出来的？这有什么解释吗？是的，覆盖是在
测试期间完成的。仅仅60%的覆盖率可能是由几件事造成的。可能是某些很难测试的代码，比如catch
代码没有被测试。如果将源代码也包含在源代码路径中，Jacoco可以向您显示已测试和未测试的代码。您可以尝试使用该任务。这将生成一个HTML报告，其中包含指向源代码的链接。
