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
How to do code coverage in remote container using Jacoco ?
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");
}
}

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;
}
