Java单元测试模拟HttpServletRequest getResourceAsStream

如何在Java单元测试中模拟HttpServletRequest

getResourceAsStream

？我使用它从servlet请求中读取资源文件

HttpServletRequest.getSession（）.getServletContext（）.getResourceAsStream（）

---

我正在使用

org.mockito.Mock

来模拟

HttpServletRequest

您需要做很多模拟。我建议使用注释：

import static org.mockito.Mockito.when;

public class TestClass{

   @Mock
   private HttpServletRequest httpServletRequestMock;

   @Mock
   private HttpSession httpsSessionMock;

   @Mock
   private ServletContext servletContextMock;

   @Before
   public void init(){
      MockitoAnnotations.initMocks(this);
   }

   @Test
   public void test(){
       // Arrange
       when(httpServletRequestMock.getSession()).thenReturn(httpSessionMock);
       when(httpSessionMock.getServletContext()).thenReturn(servletContextMock);

       InputStream inputStream = // instantiate;

       when(servletContextMock.getResourceAsStream()).thenReturn(inputStream);

       // Act - invoke method under test with mocked HttpServletRequest

   }
}
