Java 如何使用集成测试获得servlet的代码覆盖率

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

技术堆栈：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（war）
• 单元1
• 单元2

为了运行集成测试（IT），我在IntelliJ中配置了Tomcat，使其在8081端口上运行。为了执行IT，我们一直在

http://localhost:8081/rm-xsp/servletname

下面是我的

pom

和

mvn clean verify-Pone

是我的maven目标

我好像错过了什么。我在同一个网站上浏览了很多帖子，但都没有找到解决办法

非常感谢您的任何建议。

工具的目标似乎不受任何阶段的约束（您是否看到它在maven日志中运行？）。尝试将其绑定到

预集成测试

@guido尝试过，但没有成功。我仍然认为代码覆盖率为“0”。我的电脑运行成功。请参考上面文章中我的测试执行输出。似乎您正在定义：

failsafeArgLine

，但是您没有将其设置为failsafe执行；尝试添加它：

${failsafeArgLine}

在maven failsafeplugint的

元素中添加它。我看到现在创建了

jacocoit.exec

。但是当报告进来时，我看到

[mkdir]创建的dir:C:\Users\WorkSpace\usage\u service\autoTestEnv\target\coverage report[report]正在加载执行数据文件C:\Users\WorkSpace\usage\u service\autoTestEnv\target\coverage reports\jacoco it.exec

消息。我觉得报告关注的是autoTestEnv文件夹的目标\类，而不是servlet文件夹。您在该位置找到文件的唯一原因是您在配置中设置了该文件；当jacoco对类进行仪器化时，它使用在target中收集的类
