投的Mockito ActionForm來

Question

類

我有下面的行的代碼中的問題：

OrderForm of = (OrderForm)form; 

形式的ActionForm和OrderForm是擴展的ActionForm的類。

但我試圖測試這種方法，我不知道如何做到這一點。

對於參考，這是該方法：

OrderForm of = (OrderForm)form; 
     System.out.println(Integer.parseInt(getPublisherId(req))); 
     of.setPublisherId(Integer.parseInt(getPublisherId(req))); 

     AdvertiserManager am = new AdvertiserManager(); 
     OrderManager om = new OrderManager(); 
     of = om.getOrder(of, Locale.getDefault()); 
     //If no valid campaign was found the id of 'of' is 0. So if id = 0 return 404 status. 
     if (of.getId() == 0) { 
      response.setStatus(HttpServletResponse.SC_NOT_FOUND); 
      return null; 
     } 

方法簽名：

public ActionForward performAction(ActionMapping mapping, ActionForm form, HttpServletRequest req, HttpServletResponse response)

測試：

private IPOrderApiAction spy; 

@Test 
public void testGetOrderApiCallNotExistingCampaignId() { 
    MockHttpServletRequest request = new MockHttpServletRequest(); 
    MockHttpServletResponse response = new MockHttpServletResponse(); 
    ActionMapping mapping = mock(ActionMapping.class); 
    ActionForm form = mock(ActionForm.class); 
    OrderForm of = mock(OrderForm.class); 
    Map<String,Object> map = new HashMap<String,Object>(); 
    map.put("id", "1261"); 
    spy = Mockito.spy(new IPOrderApiAction()); 
    Mockito.doReturn("1").when((IPAuthenticatedAction)spy).getPublisherId(request); 
    request.setParameters(map); 
    when(mapping.getParameter()).thenReturn("getOrder"); 
    spy.performAction(mapping,form, request, response); 
    assertEquals(HttpServletResponse.SC_NOT_FOUND, response.getStatus()); 
} 

它的struts 1.1

Answer 1

你不及格OrderForm的實例來你的方法，但ActionForm中的實例：

ActionForm form = mock(ActionForm.class); 
... 
spy.performAction(mapping,form, request, response); 

對於中投成功，形式必須是OrderForm的一個實例，所以你需要

ActionForm form = mock(OrderForm.class); 
... 
spy.performAction(mapping, form, request, response);
