Tomcat7 Maven插件和JaCoCo [英] Tomcat7 Maven Plugin and JaCoCo
问题描述
有没有办法使用 JaCoCo 获取代码覆盖率 tomcat7-maven-plugin 嵌入式实例？
Is there any way to get code coverage using JaCoCo with the tomcat7-maven-plugin embedded instance?
jacoco-maven-plugin在我的WAR POM中配置来检测我的单元测试，但我不知道如何将jacoco代理连接到嵌入式Tomcat实例以检测我的集成测试对Tomcat运行。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进行覆盖，但如果可能的话，我更愿意坚持使用Tomcat插件。
The jacoco-maven-plugin is configured in my WAR's POM to instrument my unit tests, but I'm not sure how to attach the jacoco agent to the embedded Tomcat instance to instrument my integration tests that run against Tomcat. Given that the Tomcat instance is embedded, I'm not sure if this approach is possible. Is there any other way to accomplish this? I can probably switch from using the Tomcat Maven Plugin to using Cargo to get coverage, but I'd prefer to stick with the Tomcat plugin if possible.
这里有一些来自我的POM的相关片段：
Here are a few relevant snippets from my POM:

推荐答案
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。切换到货物我能够这样做。
I know its been awhile since the question was posted but I don't feel the answer really addressed the root of the problem. Code coverage may work with failsafe or surefire if you are running tests within those plugins. However, if you just want to monitor tomcat with jacoco to get a coverage report current information doesn't provide that. I found that the tomcat7-maven-plugin doesn't allow you to inject the -javaagent for jacoco by simply providing JAVA_OPTS. Switching to cargo I was able to do that like so.

重要部分是：
-
< plugin>< groupId> org.jacoco< / groupId> ...< propertyName> jacoco.agent.itArgLine< / propertyName> -
< cargo.jvmargs> $ {jacoco。 agent.itArgLine}，output = tcpserver，port = 6300< /cargo.jvmargs>
<plugin><groupId>org.jacoco</groupId> ...<propertyName>jacoco.agent.itArgLine</propertyName><cargo.jvmargs>${jacoco.agent.itArgLine},output=tcpserver,port=6300 </cargo.jvmargs>
报告目标在jacoco插件上运行，它将在$ {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。
When report target is run on the jacoco plugin it will create a directory in ${projectbase}/target/site/jacoco-it/index.html with your coverage report. I use this with the soapui-maven-plugin but it could be used with selenium-maven-plugin also.
