在运行JUnit时，使用CDI bean注入EJB 3.1的问题

Question

我使用@inject创建了一个EJB3.1并注入了CDI bean，但是在单元测试时遇到了一些问题，但是当从servlet测试它工作正常时。我在WEB-INF文件夹中有beans.xml。下面是我的EJB代码：

@Stateless
public class CdiUsingEjb {
    @Inject
    private HelloServletCDIPojo helloServletCDIPojo;

    public String greet() {
        assert helloServletCDIPojo != null;
        return helloServletCDIPojo.from();
    }
}

以下是我的CDI bean：

public class HelloServletCDIPojo {
    public String from() {
        return "from HelloServletStateless CDI";
    }
}

我创建了一个JUnit类：

public class CdiUsingEjbTest {
    @EJB
    private CdiUsingEjb cdiUsingEjb;

    @Before
    public void setUp() throws Exception {
        EJBContainer.createEJBContainer().getContext().bind("inject", this);
    }

    @Test
    public void test() {
        assertNotNull(cdiUsingEjb);
    }
}

当我运行此JUnit测试时，我收到以下错误。

org.apache.openejb.OpenEjbContainer$AssembleApplicationException: org.apache.openejb.OpenEJBException: Creating application failed: /Users/prasannakumar/freelanceWorkspace/javaWorkspace/TomEEExamples: couldn't start owb context
