[SPRING] Struts2.3.12 junit4 테스트 케이스 요청 및 세션이 null입니다.

SPRING

Struts2.3.12 junit4 테스트 케이스 요청 및 세션이 null입니다.

나는 이미이 해결책을 경험했다 : Struts 2 JUnit Plugin v2.2.3 : 테스트 클래스 확장 StrutsTestCase; '요청'이 null입니다.

그러나 나는 이미 struts2-spring 플러그인을 가지고 있지 않으며, 둘 다 Spring에서도 사용하고 있지 않습니다.

나는 3 개의 테스트 케이스를 가지고 있고, 2 개는 요청이 null 일 때 실패하고 하나는 세션이 null 일 때 실패한다.

일부 종속성 문제가 있다고 생각합니다. 몇 가지 종속성을 하나씩 제거하려고 시도했지만 어느 것도 작동하지 않습니다.

업데이트 - 테스트 결과는 다음과 같습니다.

@Test
public void login() throws Exception {
    request.setParameter("email", "nitin.cool4urchat@gmail.com");
    request.setParameter("password", "22");
    ActionProxy proxy = getActionProxy("login");
    String result = proxy.execute();
    assertEquals("success", result);
    System.out.println(response.getContentAsString());
}

@Test
public void testView() throws Exception {
    ActionProxy proxy = getActionProxy("/optimize/view");
    String result = proxy.execute();
    assertEquals("success", result);
    System.out.println(response.getContentAsString());

    proxy = getActionProxy("/optimize/view/23");
    result = proxy.execute();
    assertEquals("success", result);
    System.out.println(response.getContentAsString());

    proxy = getActionProxy("/optimize/view/110");
    result = proxy.execute();
    assertEquals("success", result);
    System.out.println(response.getContentAsString());
}

@Test
public void testSave() throws Exception {
    request.setContent("{\"id\":\"1\",\"name\":\"nitin\"}".getBytes());
    request.addHeader("Content-Type", "application/json");
    request.setMethod("POST");

    ActionProxy proxy = getActionProxy("/save");
    actions.IoOptimizationAction myAct = (actions.IoOptimizationAction) proxy.getAction();

    String result = proxy.execute();

    assertEquals("success", result);
    System.out.println(response.getContentAsString());
}

업데이트 제안 된 executeAction으로 테스트를 변경 했으므로 2 차 테스트는 다음과 같이 보입니다.

 @Test
    public void testView() throws Exception {
        System.out.println(ActionContext.getContext());
        System.out.println(executeAction("optimize/view"));
}

해결법

  1. ==============================

    1.getActionProxy 메소드를 사용하여 작업을 실행하는 경우 새 세션 맵을 호출 컨텍스트로 설정해야합니다.

    getActionProxy 메소드를 사용하여 작업을 실행하는 경우 새 세션 맵을 호출 컨텍스트로 설정해야합니다.

    ActionProxy actionProxy = getActionProxy("/action");
Map<String, Object> sessionMap = new HashMap<String, Object>();
actionProxy.getInvocation().getInvocationContext().setSession(sessionMap);
actionProxy.execute();

    액션 프록시에 대한 참조가 필요 없다면 executeAction 메소드를 사용할 수 있습니다. executeAction은 execute 메소드에서 반환 된 결과가 아니라 결과의 실제 결과를 반환합니다.

  2. ==============================

    2.제 경우에는 super.setUp을 테스트에서 호출해야했습니다.

    제 경우에는 super.setUp을 테스트에서 호출해야했습니다.

  3. ==============================

    3.요청이 null이되지 않도록하려면 다음을 수행하십시오.

    요청이 null이되지 않도록하려면 다음을 수행하십시오.

    request = new MockHttpServletRequest();

    세션 :

    Map<String, Object> sessionMap = new HashMap<String, Object>();
actionProxy.getInvocation().getInvocationContext().setSession(sessionMap);
