[SPRING] 유닛 테스트를위한 객체 MockHttpServletResponse 생성 오류

유닛 테스트를위한 객체 MockHttpServletResponse 생성 오류

아래의 책처럼 자바 서블릿을 테스트하고 싶습니다. 실용적인 TDD 및 수락 TDD 자바 개발자 :

package sample;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class LoginServlet extends HttpServlet {
    private boolean isValid;

    /**
     * 
     */
    private static final long serialVersionUID = 2473252741884321641L;

    @Override
    public void init() throws ServletException {
        super.init();

    }

    @Override
    public void doPost(HttpServletRequest req, HttpServletResponse resp)
            throws IOException {
        String user = req.getParameter("j_username");
        String pass = req.getParameter("j_password");
        if (isValidLogin(user, pass)) {
            resp.sendRedirect("/frontpage");
            req.getSession().setAttribute("username", user);
        } else {
            resp.sendRedirect("/invalidlogin");
        }

    }

    private boolean isValidLogin(String user, String pass) {
        return isValid;
    }

    public void setValid(boolean isValid) {
        this.isValid = isValid;
    }

}

내 코드는 다음과 같습니다.

    package sample;
    import static org.junit.Assert.assertEquals;
    import org.junit.Test;
    import org.springframework.mock.web.MockHttpServletRequest;
    import org.springframework.mock.web.MockHttpServletResponse;

    public class SprintTestProb {

    @Test
    public void wrongPasswordShouldRedirectToErrorPage() throws Exception {
        MockHttpServletRequest request = new MockHttpServletRequest();
        MockHttpServletResponse response = new MockHttpServletResponse();
        request.addParameter("j_username", "gyanu");
        request.addParameter("j_password", "wrongpassword");
        LoginServlet login = new LoginServlet();
        login.setValid(false);
        login.doPost(request, response);
        assertEquals("/invalidlogin", response.getRedirectedUrl());
    }

}

나는 라인에 오류가있다. MockHttpServletResponse response = new MockHttpServletResponse (); 다음과 같이

해결법

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

   1.javaee-api의 의존성을 javax.selvlet-api로 대체해야한다.

   javaee-api의 의존성을 javax.selvlet-api로 대체해야한다.

   <dependency>
     <groupId>javax.servlet</groupId>
     <artifactId>javax.servlet-api</artifactId>
     <version>3.1.0</version>
   </dependency>
   

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

   2.테스트 용 스프링 프레임 워크 레퍼런스 (Spring Framework Reference for Testing)에 따르면, 당신은 모의를 autowire하기 위해 어노테이션을 사용해야 만합니다. 스프링 참조의 예 :

       @Autowired MockServletContext servletContext; // cached
   
       @Autowired MockHttpSession session;
   
       @Autowired MockHttpServletRequest request;
   
       @Autowired MockHttpServletResponse response;
   
       @Autowired ServletWebRequest webRequest;
   
       //...
   }
   

   `

   다른 예 (주석 없음)는 여기에서 찾을 수 있습니다.

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

   3.비슷한 문제가있어서이 종속성을 내 pom에 추가하여 javaee-api를 javax.servlet로 변경할 필요가 없습니다.
