当业务测试从不同的代码库执行时，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。
我的应用是一组部署在tomcat上的war文件。
应用程序代码库与测试代码库是分开的。
为了获得报道，我遵循了以下步骤。
1使用maven编译测试代码。
2将应用程序类从构建位置 (${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 构建:我已经保留了

jbehave 测试使用:

当我执行 mvn mvn install -Pcoverage 时
执行过程如下。

有了这个，我得到了一份与应用程序包一起生成的覆盖率报告。但是覆盖率显示为0%
在 session 链接中，应用程序类未加载。 截图:
有人可以帮我吗？
最佳答案
我是这样解决的
将应用程序类复制到检测文件夹中。
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(我在布局时将 jacoco-agent jar 复制到了我的项目中)
执行测试(这可以是自动的或手动的)
停止tomcat服务器(
jacoco-coverage.exec此时更新)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。
感谢@jens-schauder 指点我发布这个作为答案。
关于java - Jacoco 测试覆盖率报告显示 0%，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/20219936/
