Two Test Cases 추가 (Received message and hashed password )

in test/java/com/example/backend

package com.example.backend;

import static org.assertj.core.api.Assertions.assertThat;

import java.util.List;

import org.junit.jupiter.api.Order;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.TestMethodOrder;
import org.junit.jupiter.api.MethodOrderer.OrderAnnotation;
import org.junit.jupiter.api.extension.ExtendWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.context.SpringBootTest.WebEnvironment;
import org.springframework.boot.test.web.client.TestRestTemplate;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.junit.jupiter.SpringExtension;

import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;

import com.example.backend.shared.GenericResponse;
import com.example.backend.user.User;
import com.example.backend.user.UserRepository;

@ExtendWith(SpringExtension.class)
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)
@ActiveProfiles("test")
@TestMethodOrder(OrderAnnotation.class)
public class UserControllerTest {

    @Autowired
    TestRestTemplate testRestTemplate;

    @Autowired
    UserRepository userRepository;

    private static final String API_1_0_USERS = "/api/1.0/users";

    private User createValidUser() {
        User user = new User();
        user.setUsername("test-user");
        user.setDisplayName("test-display");
        user.setPassword("Password");
        return user;
    }

    @Test
    @Order(1)
    public void postuser_whenUserIsValid_userSaveToDatabase() {
        User user = createValidUser();
        testRestTemplate.postForEntity(API_1_0_USERS, user, Object.class);
        assertThat(userRepository.count()).isEqualTo(1);
    }

    @Test
    @Order(2)
    public void postuser_whenUserIsValidreceiveOK() {
        User user = createValidUser();
        ResponseEntity<Object> response = testRestTemplate.postForEntity(API_1_0_USERS, user, Object.class);
        assertThat(response.getStatusCode()).isEqualTo(HttpStatus.OK);
    }

    @Test
    @Order(3)
    public void postuser_whenUserIsValid_receiveSuccessMessage() {
        User user = createValidUser();
        ResponseEntity<GenericResponse> response = testRestTemplate.postForEntity(API_1_0_USERS, user, GenericResponse.class);
        assertThat(response.getBody().getMessage()).isNotNull();
    }

    @Test
    @Order(4)
    public void postUser_whenUserIsValid_passwordIsHashedInDataBase(){
        User user = createValidUser();
        testRestTemplate.postForEntity(API_1_0_USERS, user, Object.class);
        List<User> users = userRepository.findAll();
        User inDB = users.get(0);
        assertThat(inDB.getPassword()).isNotEqualTo(user.getPassword());            
    }
}

Test cases: postuser_whenUserIsValid_receiveSuccessMessage & postUser_whenUserIsValid_passwordIsHashedInDataBase 추가

H2 Database console 설정

spring:
    datasource:
        generate-unique-name: false
    h2:
        console:
            enabled: true
            path: /h2-console

application.properties에서 application.yml으로 변경함
실행후 H2 DB사용을 위해 Path를 추가함 http://localhost:8080/h2-console
generate-unique-name: false으로 setting하여 JDBC URL변경없이 사용함.

GenericResponse.java class 추가

in java/com/example/backend/shared

package com.example.backend.shared;

import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@NoArgsConstructor
public class GenericResponse {
    private String message;

    public GenericResponse(String message){
        this.message = message;
    }
    
}

@NoArgsConstructor will generate a constructor with no parameters.

UserService.java class에 encode method 사용

in java/com/example/backend/shared

package com.example.backend.user;

import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.stereotype.Service;

@Service
public class UserService {

    UserRepository userRepository;

    BCryptPasswordEncoder passwordEncoder;
    
    public UserService(UserRepository userRepository){
        super();
        this.userRepository = userRepository;
        this.passwordEncoder = new BCryptPasswordEncoder();
    }

    public User save(User user){
        user.setPassword(passwordEncoder.encode(user.getPassword()));
        return userRepository.save(user);
    }

}

in UserController.java class Return값 변경

in java/com/example/backend/shared

package com.example.backend.user;

import com.example.backend.shared.GenericResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class UserController {

    @Autowired
    UserService userService;
    

    @PostMapping("/api/1.0/users")
    public GenericResponse createUser(@RequestBody User user){
        userService.save(user);
        // GenericResponse body = new GenericResponse();
        // body.setMessage("User saved");
        return new GenericResponse("User saved");
    }
}
