模拟ActionContext.getContext().getSession()返回null [英] Mocking ActionContext.getContext().getSession() returns null

问题描述

我正在尝试为以下方法编写jUnit测试用例.

I am trying to write jUnit test case for following method.

public class MyClass {

  public static Map<String, Object> getSession() {
    Map<String, Object> session = ActionContext.getContext().getSession();
    return session;
  }
}

我遵循了此问题以及此问题，并尝试模拟ActionContext.但是会话仍然是null.

I followed this question and also this question and tried to mock ActionContext. But still session is null.

    public class TestClass {

        private HttpServletRequest request;
        private HttpSession session;

        @Before
        public void setUp() {
            // mock the session
            session = mock(HttpSession.class);
            // mock the request
            request = mock(HttpServletRequest);
            when(request.getSession()).thenReturn(session);

            // set the context
            Map<String, Object> contextMap = new HashMap<String, Object>();
            contextMap.put(StrutsStatics.HTTP_REQUEST, request);
            ActionContext.setContext(new ActionContext(contextMap));
        }

        @After
        public void destroyTests() {
           ActionContext.setContext(null);
        }

@Test
    public void testGetSession() {        
        Map<String, Object> session =MyClass.getSession();
        //session is null here

    }

}

我在这里做错什么了吗?

Is there something I am doing wrong here ?

推荐答案

将以下代码添加到上下文映射中，因为它是空上下文，因此您应将会话设置为操作上下文.

Add the following code to the context map, since it's empty context created you should set the session into action context.

contextMap.put(ActionContext.SESSION, new SessionMap(request));
