Jacoco测试覆盖率报告显示0％

Question

从不同的代码库执行业务测试时，我必须获得应用程序的代码覆盖率。

我使用：Maven作为我的构建Jbehave作为我的测试框架。测试是用Java编写的。

我的应用程序是部署在tomcat上的一组war文件。

应用程序代码库与测试代码库是分开的。

为了获得覆盖范围，我遵循以下步骤。

1使用maven编译测试代码。

2将应用程序类从其构建位置（$ {app.code.dir} / target
/ classes）复制到$ {test.code.dir} / target / classes

[3]通过Maven运行测试和jacoco报告

mvn版本：我保留了

当我执行mvn mvn install -Pcoverage

执行如下。

这样，我得到了与应用程序包一起生成的覆盖率报告。但覆盖率显示为0％

在会话链接中，未加载应用程序类。屏幕截图：

有人可以帮我吗？

Answer 1

我能够解决以下问题

1. 将应用程序类复制到检测文件夹中。

2. 使用Java参数启动应用服务器（在mycase中为tomcat）

   -javaagent:$WORKSPACE/target/lib/jacoco-agent-0.6.3.2.jar=includes=*,destfile=$‌​TOMCAT_HOME/jacoco-coverage.exec,append=false
   

（我在布局中将jacoco-agent jar复制到了我的项目中）

1. 执行测试（可以是自动的也可以是手动的）

2. 停止tomcat服务器（此时jacoco-coverage.exec已更新）

3. 执行蚂蚁报告目标。指向更新的jacoco-coverage.exec并复制了应用程序类文件夹。
