的JUnit測試FacesContext.getExternalContext

Question

我在一個Java EE下面的代碼託管bean：

FacesContext context = facesContextProvider.getCurrentInstance(); 
HttpServletResponse response = (HttpServletResponse) context.getExternalContext(); 

哪裏facesContextProvider是返回faces上下文（用於模擬測試非常有用）的自定義類。

我想知道如何在使用mockito的JUnit中進行測試。我正試着組合：

FacesContextProvider mockFacesContextProvider = mock(FacesContextProvider.class); 
when(mockFacesContextProvider.getCurrentInstance()).thenReturn(mockFacesContext); 
// this line is wrong ~> when(mockFacesContext.getExternalContext()).thenReturn((ExternalContext) new MockHttpServletResponse()); 

如何注入某種模擬或自定義HttpServletResponse到我的外部上下文中？

感謝您的幫助。

ANSWER

我的控制器代碼是錯誤的。您可以使用ExternalContext來執行您所需的任何操作。因此，在控制器，它實際上應該是：

FacesContext facesContext = facesContextProvider.getCurrentInstance(); 
ExternalContext externalContext = facesContext.getExternalContext(); 
externalContext.responseReset(); 

如果你還想要回應，你可以得到它：

HttpResponse response = externalContext.getResponse(); 

然後將單元測試工具是：

mockFacesContextProvider = mock(FacesContextProvider.class); 
mockFacesContext = mock(FacesContext.class); 
mockExternalContext = mock(ExternalContext.class); 
mockHttpSession = mock(HttpSession.class); 
when(mockFacesContextProvider.getCurrentInstance()).thenReturn(mockFacesContext); 
when(mockFacesContext.getExternalContext()).thenReturn(mockExternalContext); 
when(mockExternalContext.getSession(true)).thenReturn(mockHttpSession); 

然後單元測試代碼將是：

verify(mockExternalContext).responseReset();

FacesContextProvider mockFacesContextProvider = mock(FacesContextProvider.class); 
HttpServletResponse mockResponse = mock(HttpServletResponse.class); 
when(mockFacesContextProvider.getCurrentInstance()).thenReturn(mockFacesContext); 
when(mockFacesContext.getExternalContext()).thenReturn(mockResponse);
