使用 arquillian 进行 EAR 集成测试

Question

我有以下真实的项目结构：

EAR
 - lib/commons.jar
 - lib/another dependencies
 - ejb.jar

我想用 arquillian 测试它，但我总是遇到异常。

这是我构建 EAR 的 java 方法：

@Deployment
public static Archive<?> createTestArchive() {
    //create ear
    EnterpriseArchive ear = ShrinkWrap
            .create(EnterpriseArchive.class, "test-app.ear");

    // create ejb-jar
    JavaArchive ejb = ShrinkWrap
            .create(JavaArchive.class, "test-ejb.jar")
            .addPackage("a.b.ejb")
            .addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");

    // resolve ejb dependencies
    File[] dependencies = Maven.resolver()
            .loadPomFromFile("pom.xml")
            .importDependencies(ScopeType.COMPILE, ScopeType.TEST)
            .resolve()
            .withTransitivity()
            .asFile();

    ear.addAsModule(ejb);
    ear.addAsLibraries(dependencies);
    ear.setApplicationXML("glassfish-resources.xml");

    LOGGER.debug("content: " + ear.toString(true));
    return ear;
}

内容看起来不错，但有些地方不太好，因为我得到了这个异常：

ArquillianServletRunner not found.
Could not determine ContextRoot from ProtocolMetadata, please contact DeployableContainer developer.

JAR 内容：

/a/
/a/b/
/a/b/ejb/
/a/b/ejb/MyEjb.class
...
/META-INF/
/META-INF/beans.xml

EAR 内容

/lib/postgresql-42.0.0.jar
/META-INF/
/META-INF/application.xml

我收到“ArquillianServletRunner not found”错误的原因是因为 EJB 级别存在错误。

以下测试代码正常运行：

@RunWith(Arquillian.class)
public class EchoServiceBeanTest {

    @EJB
    private EchoService echoService;

    @Deployment
    public static Archive<?> createDeployment() {
        // create ear
        EnterpriseArchive ear = ShrinkWrap
                .create(EnterpriseArchive.class, "test-app.ear");

        // create ejb.jar
        JavaArchive ejb = ShrinkWrap
                .create(JavaArchive.class, "test-ejb.jar")
                .addPackages(true, "a.b.ejb")
                .addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");
        LOGGER.debug("EJB content: " + ejb.toString(true));

        // build ear
        ear.addAsModule(ejb);

        LOGGER.debug("EAR deployment content: " + ear.toString(true));
        return ear;
    }

    @Test
    public void echo() throws Exception {
        Assert.assertNotNull(echoService);
        String expected = "hello";
        String returned = echoService.echo(expected);
        Assert.assertEquals(expected, returned);
    }
}

使用的maven依赖：
