使用Web套接字在Arquillian TomEE嵌入式测试中进行CDI注入

Question

我正在编写我的@ServerEndpoint的一些集成测试，在最终运行端点之后，我现在在@OnOpen中得到一个nullpointer，因为注入失败了。

我已经在github上传了代码：https://github.com/runarhk/Websockets-Test

端点的定义如下：

@ServerEndpoint("/test")
public class MyEndpoint{

    @Inject
    private SessionHandler sessionHandler;

    @OnOpen
    public void open(Session session) {
        sessionHandler.addSession(session);//sessionhandler is @Singleton
    }

    @OnClose
    public void close(Session session) {
    }

    @OnError
    public void onError(Throwable error) {
    }

    @OnMessage
    public void handleMessage(String payload, Session session) {
    }
}

@Singleton
public class SessionHandler {
    public void addSession(Session session){}

}

@ClientEndpoint
public class SocketClient {

    @OnOpen
    public void onOpen(Session session) {
    }

    @OnMessage
    public void onMessage(String message, Session session) {
    }

    @OnClose
    public void onClose(Session session, CloseReason closeReason) {
        LOGGER.info(String.format("Session %s close because of %s",     session.getId(), closeReason));
    }

    public SocketClient openConnection(URL url) {//URL injected arquillian resource, where url is for http connection..
        WebSocketContainer container = ContainerProvider.getWebSocketContainer();
        try {
            SocketClient  client = new SocketClient();
            URI uri = URI.create(url.toString().replace("http", "ws") + "test");
            container.connectToServer(client, uri);
            return client;
        } catch (DeploymentException | IOException ex) {
            LOGGER.log(Level.SEVERE, null, ex);
            throw new RuntimeException(ex);
        }
    }

    public void closeConnection() {
        try {
            session.close(new CloseReason(CloseReason.CloseCodes.NORMAL_CLOSURE, "Client requested close"));
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }
}

我的测试是用spock编写的，在设置中失败

@RunWith(ArquillianSputnik)
class SocketIT extends Specification {

    @Deployment
    public static Archive archive() {
       return ShrinkWrap.create(WebArchive.class, "test-sockets.war")
           .addAsWebInfResource(EmptyAsset.INSTANCE, ArchivePaths.create("beans.xml"))
           .addClasses(MyEndpoint.class, SessionHandler.class);
    }
    @ArquillianResource
    URL url;

    SocketClient client;

    def setup() {
        client = SocketClient.openConnection(url);
    }

    def cleanup() {
        client.closeConnection();
    }

    def 'test connection'() {
        given: 'payload'
            def payload = "abc"
        when: 'sending payload'
            client.sendMessage(payload)
        then: 'it should not fail'
            ass
    }
}

我的Arquillian.xml文件如下所示：

</arquillian>

编辑： 我刚下载到1.7.2-plus并在那里运行我的应用程序。它就像一个魅力。那么这可能与tomee-embedded不是一个加号变体有关？
