Question

我想测试一个EJB，我想用Weld EE Embedded测试它，因为我不想为此部署一个应用服务器。

这是我的班级：

@RunWith(Arquillian.class)
public class EJBTest {
    @Deployment
    public static JavaArchive createTestArchive() {
        return ShrinkWrap
                .create(JavaArchive.class, "test.jar")
                .addAsManifestResource(EmptyAsset.INSTANCE, ArchivePaths.create("beans.xml"));
    }

    @Stateless
    public static class SomeService {
        public String someMethod() {
            return "test";
        }
    }

    @Inject
    SomeService someService;

    @Test
    public void testStatelessCall() {
        Assert.assertEquals("test", someService.someMethod());
    }
}

这是我的pom.xml依赖项：

在测试我的课程时，我有一个NPE：

有人有解决方案吗？

Answer 1

这似乎是一个Weld EE错误。

查看相应的Arquillian forum thread和the associated issue on Weld Issue Tracker。

Answer 2

尝试使用@EJB而不是@Inject。

Answer 3

而不是'arquillian-weld-ee-embedded-1.1'，尝试使用'arquillian-weld-se-embedded-1.1'。这确实是一个错误，这应该解决它。

编辑：看到你已经解决了，我的不好：）
