Jacoco 的 Arquillian 集成测试代码覆盖问题

Question

我正在使用 arquillian 和 tomee 远程插件进行集成测试。它运作良好。但是我的代码覆盖率不起作用。我正在使用 Jacoco 插件进行代码覆盖。在我的 Java class java.lang.instrument.IllegalClassFormatException 中出现异常：检测 com/demo/EmpService

时出错

如何使用 Jacoco 在远程容器中进行代码覆盖？

注意： 我已将 javaagent ( argLine ) 传递给处于集成阶段的服务器 catalina opts。我在测试 class 中注入我的 bean 并试图覆盖测试用例。测试用例通过。但没有代码覆盖率并出现异常

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");
    }
}

我通过询问 JaCoCo 开发人员 (here) 找到了您的解决方案。它似乎与 TestNG 有关。如果你将 TestNG 库添加到你的 Arquillian 容器中，你的覆盖范围应该是固定的。您的修改示例如下所示。

@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;
}
