Tomcat7 Maven插件和JaCoCo

she*_*ley 17 java tomcat maven jacoco

有没有办法使用JaCoCo和tomcat7-maven-plugin嵌入式实例获取代码覆盖？

jacoco-maven-plugin在我的WAR POM中配置来检测我的单元测试,但我不确定如何将jacoco代理连接到嵌入式Tomcat实例来检测针对Tomcat运行的集成测试.鉴于嵌入了Tomcat实例,我不确定这种方法是否可行.有没有其他方法可以实现这一目标？我可以从使用Tomcat Maven插件切换到使用Cargo获取覆盖范围,但如果可能的话,我宁愿坚持使用Tomcat插件.

以下是我POM的一些相关摘要:

我知道自问题发布以来已经过了一段时间,但我觉得答案并没有真正解决问题的根源.如果您在这些插件中运行测试,代码覆盖可能适用于failsafe或surefire.但是,如果您只想用jacoco监视tomcat以获取覆盖率报告,则当前信息不提供此信息.我发现tomcat7-maven-plugin不允许你通过简单地提供JAVA_OPTS来为jacoco注入-javaagent.切换到货物我能够做到这一点.

重要的部分是:

  1. <plugin><groupId>org.jacoco</groupId> ...<propertyName>jacoco.agent.itArgLine</propertyName>
  2. <cargo.jvmargs>${jacoco.agent.itArgLine},output=tcpserver,port=6300 </cargo.jvmargs>

当在jacoco插件上运行报告目标时,它将在$ {projectbase} /target/site/jacoco-it/index.html中创建一个包含您的覆盖率报告的目录.我在soapui-maven-plugin中使用它,但它也可以与selenium-maven-plugin一起使用.

如果您使用maven-failsafe-plugin（或 maven-surefire-plugin）来运行集成测试，则不需要将JAVA_OPTS传递给嵌入的tomcat 。这是因为tomcat嵌入在maven-failsafe-plugin的同一进程中运行。

因此，当jacoco-maven-plugin执行prepare-agent时，它也会设置maven-failsafe-plugin 使用的argLine。

我创建了一个项目来测试这个，在 pom 的下面部分：
