我正在尝试获取集成测试的代码覆盖率报告。 Jacoco maven插件能够为单元测试提供代码覆盖率，但为集成测试提供0％的覆盖率。集成测试正在击中应用程序的其余api端点，该端点已部署在tomcat中。
我的maven jacoco插件＆amp; surefire插件看起来像这样。

我正在测试阶段执行单元测试＆amp;集成测试阶段的集成测试。 我得到的最新错误是“由于缺少执行数据文件而跳过JaCoCo执行。”
答案 0 :(得分：1)
引用documentation of prepare-agent-integration：
与prepare-agent相同，但提供适用于集成测试的默认值：
- 绑定到预集成测试阶段
- 不同的destFile
引用documentation of prepare-agent：
准备一个指向JaCoCo运行时代理的属性，该属性可以作为VM参数传递给被测试的应用程序。默认情况下，根据项目打包类型设置具有以下名称的属性：
- tycho.testArgLine用于包装类型eclipse-test-plugin和
- argLine否则。
在大多数情况下，argLine会自动选择maven-surefire-plugin来启动JVM以执行单元测试 - http://maven.apache.org/surefire/maven-surefire-plugin/test-mojo.html#argLine
argLine：在命令行上设置的任意JVM选项。
这解释了为什么您要获得单元测试的覆盖率。
要获得集成测试的覆盖范围，您必须确保将此属性传递给正在测试的应用程序的JVM，即执行Tomcat的JVM，这完全取决于您启动它的方式。< / p>

在Evgeny的帮助下，我完成了这项工作。 将服务器更改为glassfish＆amp; ide to intellij以便于调试。
使用以下JVM选项启动glassfish服务器。
