Spring boot api test code

json을 포함하여 body를 받아야하는 post api로 test를 하겠다.

 

test를 진행할 controller 이다.

 

package com.lof.lofserver.controller.user;

import com.lof.lofserver.controller.user.request.UserInfoDto;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.*;

@RestController
@RequestMapping("/v1/user")
public class UserController {

    @PostMapping("/create")
    public ResponseEntity<?> createUser(@RequestBody UserInfoDto userInfoDto){
        return null;
    }
}

test 코드이다.

 

import com.fasterxml.jackson.databind.ObjectMapper;
import com.lof.lofserver.controller.user.request.UserInfoDto;
import org.junit.jupiter.api.DisplayName;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.ResultActions;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;

@WebMvcTest(controllers = UserController.class)
class UserControllerTest {

    @Autowired
    private MockMvc mvc;

    @Autowired
    private ObjectMapper objectMapper;

    @Test
    @DisplayName("유저 생성 테스트")
    public void userCreate() throws Exception{
        //given
        String googleAccessToken = "googleAccessToken";
        String fcmToken = "fcmToken";
        UserInfoDto userInfoDto = new UserInfoDto(googleAccessToken, fcmToken);

        //when
        ResultActions resultActions = mvc.perform(
                MockMvcRequestBuilders.post("/v1/user/create")
                        .contentType("application/json")
                        .content(objectMapper.writeValueAsString(userInfoDto)));

        //then
        resultActions.andExpect(MockMvcResultMatchers.status().isOk());
    }

}

 

대부분의 test code는 given, when, then으로 구성을 하는것이 좋으며

@WebMvcTest 어노테이션으로 test를 진행할 controller를 등록하고

MockMvc 를 이용하여서 test를 하였다.

ObjectMapper는 객체를 json string화 하기 위해서 사용하였다.

 

static 을 사용하면 조금더 깔끔해진다.

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.post;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

public void userCreate() throws Exception{
    //given
    String googleAccessToken = "googleAccessToken";
    String fcmToken = "fcmToken";
    UserInfoDto userInfoDto = new UserInfoDto(googleAccessToken, fcmToken);

    //when
    ResultActions resultActions = mvc.perform(
            post("/v1/user/create")
            .contentType("application/json")
            .content(objectMapper.writeValueAsString(userInfoDto)));

    //then
    resultActions.andExpect(status().isOk());
}
