Seam 单元测试中的 EntityManger null

Question

下面是我试图测试的代码，但在entityManager.find上出现空指针异常，因为entityManager = null。有什么建议吗？

@Name("UserProfileConverter")
@BypassInterceptors
@Converter(forClass= UserProfile.class)
public class UserProfileConverter implements javax.faces.convert.Converter {

    @Logger
    private static Log logger;

    public Object getAsObject(FacesContext arg0, UIComponent uiComponent, String s) {
           EntityManager entityManager = (EntityManager) Component.getInstance("entityManager");

        UserProfile p;

        if(s == null || s.equals("null")) {
            return null;
        } else {
            try {
                long i = Long.parseLong(s);
                return entityManager.find(UserProfile.class, i);
            } catch (NumberFormatException e) {
                logger.error(e);
            } catch (SecurityException e) {
                logger.error(e);
            }
        }

        return null;
    }

    public String getAsString(FacesContext context, UIComponent uiComponetn, Object arg2) {
        return ((CsaRole)arg2).getCsaRoleId() + "";
    }

}

这是我的测试课..

public class UserProfileConverterTest extends SeamTest {

    private UserProfileConverter converter;
      private FacesContext mockFacesContext;
      private UIComponent mockUiComponent;

      private final static Logger logger = Logger.getLogger(UserProfileConverterTest.class);

      @BeforeClass
      public void setup() {
          converter = new UserProfileConverter();
      }
      @Test
      public void testGetAsObject()
              throws Exception {
              new ComponentTest() {

              @Override
              protected void testComponents() throws Exception {

              String value =   "11111111111";
              converter.getAsObject(mockFacesContext, mockUiComponent, value);

              }
          }.run();
      }


}

公共类 UserProfileConverterTest 扩展 SeamT​​est {

EntityManager mockEntityManager;
私有 UserProfileConverter 转换器；
UIComponent模拟UiComponent = null;
MockFacesContextmockFacesContext = null;

@课前
公共无效设置（）{
    转换器 = 新 CsaUserProfileConverter();
    mockEntityManager = EasyMock.createMock(EntityManager.class);
}


类 BaseComponentTest 扩展 ComponentTest {

    protected void testComponents() 抛出异常 {

    ScopeType.EVENT.getContext().set("entityManager",mockEntityManager);
    }
}

@测试
公共无效testGetAsObject（）抛出异常{
    新的 BaseComponentTest() {
        protected void testComponents() 抛出异常 {
            super.testComponents();

        UserProfile 预期结果 = new UserProfile();
        EasyMock.expect(mockEntityManager.find(UserProfile.class,1L)).andReturn(expectedResult);


        //重播模拟 
        EasyMock.replay(mockEntityManager);

        对象目标 = converter.getAsObject(mockFacesContext,mockUiComponent,"1");
        Assert.assertEquals(expectedResult, 目标);

        //验证模拟 
        EasyMock.verify(mockEntityManager);

        }
    }。跑步（）;
