java - 如何使用集成测试获得 servlet 的代码覆盖率

Question

我一直在尝试使用集成测试来获得实际开发代码（servlet 和其他）的代码覆盖率（代码覆盖率不适用于集成测试）。

技术栈：Java 1.8、Maven 3.3.9 和 IntelliJ Idea 2018.3

我的项目结构如下

• 集成测试模块
• Servlet 模块（战争）
• 模块 1
• 模块 2

为了运行我的集成测试 (IT)，我在 IntelliJ 中将 Tomcat 配置为在 8081 端口上运行。为了执行 IT，我们不断在本地主机上发布信息http://localhost:8081/rm-xsp/servletname

下面是我的pom，mvn clean verify -Pone是我的行家目标

我看到该coverage-report文件夹​​是使用目标下的文件夹创建的html，其中包含报告。但是没有一个java类文件有任何覆盖。参考以下：

我的输出如下：

似乎我错过了一些东西。我已经浏览了很多相同的帖子，但无法找出解决方案。

任何指示或建议都将受到高度赞赏。
