的JUnit测试FacesContext.getExternalContext

Question

我在一个Java EE下面的代码托管bean：

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

哪里facesContextProvider是返回faces上下文（用于模拟测试非常有用）的自定义类。

我想知道如何在使用mockito的JUnit中进行测试。我正试着组合：

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

如何注入某种模拟或自定义HttpServletResponse到我的外部上下文中？

感谢您的帮助。

ANSWER

我的控制器代码是错误的。您可以使用ExternalContext来执行您所需的任何操作。因此，在控制器，它实际上应该是：

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

如果你还想要回应，你可以得到它：

HttpResponse response = externalContext.getResponse(); 

然后将单元测试工具是：

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); 

然后单元测试代码将是：

verify(mockExternalContext).responseReset();

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