[英]Jacoco agent does not measure any code coverage
During the maven build process I start my app using the process-exec-maven-plugin
and run Integration tests with Failsafe. 在Maven构建过程中,我使用
process-exec-maven-plugin
启动我的应用程序,并使用Failsafe运行集成测试。 Now I want to get coverage data from the application under test. 现在,我想从被测应用程序中获取覆盖率数据。
The problem is, that the coverage report contains all the classes of my application but no coverage data (0% for all). 问题是,覆盖率报告包含我的应用程序的所有类,但没有覆盖率数据(全部为0%)。 When I append the jacoco agent to the failsafe plugin, it generates the code coverage for the test-classes which does not really help.
当我将jacoco代理附加到故障安全插件时,它会为测试类生成代码覆盖率,但实际上并没有帮助。
Any Ideas? 有任何想法吗?

In my case the problem was that the server was gone together with the docker container in "HW power off" style - there was no signal like SIGTERM on which depends output of JaCoCo (end of the JVM running in docker container). 在我的案例中,问题是服务器与“ HW关机”样式的Docker容器一起使用-没有像SIGTERM这样的信号依赖JaCoCo(在Docker容器中运行的JVM的结束)的输出。
When I add command "killall java" that docker runs inside the docker container and a small pause before the shutdown of the container, the exec file is alright. 当我添加命令“ killall java”使docker在docker容器内运行并且在关闭容器之前稍作停顿时,exec文件就可以了。
