[Web Service Project] 2. 테스트 코드 작성 & 롬복

Directory Structure

 

 

 

 

 

 

Application.java

package com.jacklee.webservice;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {
    public static void main(String[] args) { SpringApplication.run(Application.class, args); }

테스트 코드 파일 생성

 

 

 

 

 

package com.jacklee.webservice.web;

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 static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;

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

@WebMvcTest
class HelloControllerTest {

    @Autowired
    private MockMvc mvc;

    @Test
    void hello() throws Exception {
        mvc.perform(get("/hello"))
                .andExpect(status().isOk())
                .andExpect(content().string("hello"));

    }
}

테스트 코드 작성

 

 

 

 

 

 

HelloController 코드를 롬복으로 전환

 

 

mvnrepository.com/artifact/org.projectlombok/lombok

Maven Repository: org.projectlombok » lombok

 

 

Lombok 외부라이브러리를 사용하기 위해 의존성을 추가하고, 컴파일 시 새로운 플러그인 에러이슈 떄문에 아래와 같이 의존성 및 설정을 추가한다.

configurations {
	compileOnly {
		extendsFrom annotationProcessor
	}
}

dependencies {
    compileOnly 'org.projectlombok:lombok'
    annotationProcessor 'org.projectlombok:lombok'
}

롬복 디펜던시 추가

 

 

 

build.gradle

plugins {
    id 'org.springframework.boot' version '2.4.3'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
}

group 'com.jacklee.webservice'
version '1.0-SNAPSHOT'
sourceCompatibility = '1.8'

repositories {
    mavenCentral()
    jcenter()
}

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web'

    compileOnly 'org.projectlombok:lombok'
    annotationProcessor 'org.projectlombok:lombok'

    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

test {
    useJUnitPlatform()
}

 

 

 

 

 

 

 

package com.jacklee.webservice.web.dto;

import lombok.Getter;
import lombok.RequiredArgsConstructor;

@Getter
@RequiredArgsConstructor
public class HelloResponseDto {

    private final String name;
    private final int amount;

}

HelloResponseDto 생성

 

 

 

 

package com.jacklee.webservice.web.dto;

import org.junit.jupiter.api.Test;

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

class HelloResponseDtoTest {

    @Test
    void 롬복_기능_테스트() {

        //given
        String name = "test";
        int amount = 1000;

        //when
        HelloResponseDto helloResponseDto = new HelloResponseDto(name, amount);

        //then
        assertThat(helloResponseDto.getName()).isEqualTo(name);
        assertThat(helloResponseDto.getAmount()).isEqualTo(amount);
    }
}

롬복 기능 테스트

import com.jacklee.webservice.web.dto.HelloResponseDto;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {

    @GetMapping("/hello")
    public String hello() {
        return "hello";
    }

    @GetMapping("/hello/dto")
    public HelloResponseDto helloResponseDto(@RequestParam("name") String name,
                                             @RequestParam("amount") int amount) {

        return new HelloResponseDto(name, amount);
    }
}
