本文介绍了Jacoco的Arquillian集成测试代码覆盖问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在使用Arquillian和tomee远程插件进行集成测试.运行良好.但是我的代码覆盖范围不起作用.我正在使用Jacoco插件进行代码覆盖.在我的Java类中获取异常 java.lang.instrument.IllegalClassFormatException:检测com/demo/EmpService
I am doing integration testing using arquillian and tomee remote plugin. it is working good. But my code coverage is not working. I am using Jacoco plugin for code coverage. Getting Exception in my Java class java.lang.instrument.IllegalClassFormatException: Error while instrumenting com/demo/EmpService
如何使用Jacoco在远程容器中进行代码覆盖?
How to do code coverage in remote container using Jacoco ?
注意:在集成阶段，我已将javaagent(argLine)传递给服务器catalina opts.我正在将我的bean注入测试类中，并试图涵盖测试用例.测试用例通过.但是没有代码覆盖并且没有异常
Note: I have passed javaagent ( argLine ) to server catalina opts in integration phase. I am injecting my bean in test class and trying to cover test cases. Test case is passed. But no code coverage and getting exception
EmpService:
import javax.enterprise.context.ApplicationScoped;
@ApplicationScoped
public class EmpService {
public String getName(String name) {
System.out.println(" I am here ###################### "+name);
String s = "Fine";
if(name.startsWith("s")) {
s = "Welcome";
}
return s;
}
}
EmpSericeIT.java
public class EmpServiceIT extends Arquillian {
@Inject
private EmpService empService;
@Deployment
public static WebArchive createDeployment() throws IOException {
WebArchive webArchive = ShrinkWrap.create(WebArchive.class, "test.war")
.addClass(EmpService.class)
.addAsWebInfResource(EmptyAsset.INSTANCE, "beans.xml");
System.out.println(webArchive.toString(true));
return webArchive;
}
@Test
public void testService() {
assertNotNull(empService);
assertEquals(empService.getName("K"),"Fine");
assertEquals(empService.getName("s"),"Welcome");
}
}

推荐答案
我通过询问JaCoCo开发人员(此处).它似乎与TestNG有关.如果将TestNG库添加到Arquillian容器中，则覆盖率应该是固定的.修改后的示例如下所示.
I found your solution by asking the JaCoCo dev's (here). It appears to be related to TestNG. If you add the TestNG library to your Arquillian container, your coverage should be fixed. A modified example of yours is shown below.
@Deployment
public static WebArchive createDeployment() throws IOException {
PomEquippedResolveStage pomEquippedResolveStage = Maven.resolver().loadPomFromFile("pom.xml");
File[] externalLibs = pomEquippedResolveStage.resolve(
"org.testng:testng"
).withTransitivity().asFile();
WebArchive webArchive = ShrinkWrap.create(WebArchive.class, "test.war")
.addClass(EmpService.class)
.addAsLibraries(externalLibs)
.addAsWebInfResource(EmptyAsset.INSTANCE, "beans.xml");
System.out.println(webArchive.toString(true));
return webArchive;
}
