Jacoco测试覆盖率报告显示0％

我必须从不同的代码库执行业务测试时获取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。

我的应用程序是在tomcat上部署的一组war文件。

应用程序代码库与测试代码库分开。

在获得报道时，我遵循以下步骤。

1使用maven编译测试代码。

2将应用程序类从它构建的位置（$ {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

 coverage  false     org.jacoco jacoco-maven-plugin 0.6.3.201306030806   default-prepare-agent process-resources  prepare-agent   false ${basedir}/target/jacoco-coverage.exec    default-report post-integration-test  report   <!-- true -->  com/mytest/bdt/** com/mytest/bdd/**  ${basedir}/target/jacoco-coverage.exec        

使用以下命令执行jbehave测试：

   org.jbehave jbehave-maven-plugin ${jbehave.core.version}   log4j log4j 1.2.16     unpack-view-resources process-resources  unpack-view-resources    embeddable-stories test   ${embeddables5}   true true 1  ${meta.filter} -skip * +run    run-stories-as-embeddables     

当我执行mvn mvn install -Pcoverage时

执行如下。

有了这个，我得到了一个用应用程序包生成的覆盖率报告。 但覆盖范围显示为0％

在会话链接中，不加载应用程序类。 截图：

有人可以帮我吗？

Answer 1

我能够解决这个问题如下

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（mycase中的tomcat）

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

   （我将jacoco-agent jar复制到我的项目布局中）

3. 执行测试（可以是自动或手动）

4. 停止tomcat服务器（ jacoco-coverage.exec更新jacoco-coverage.exec ）

5. 执行ant报告目标。 指向更新的jacoco-coverage.exec和复制的应用程序类文件夹。
