[TDD] POJO를 스프링부트 테스트로 전환하기

POJO로 된 서비스를 스프링빈으로 등록하여 스프링부트 테스트로 변경하기

 

스프링부트 테스트로 전환하기 위해 아래와 같이 각 클래스 파일에 어노테이션을 추가해준다.

 

ProductService.java

package com.example.productorderservice.product;

import org.springframework.stereotype.Component;

@Component // 추가
class ProductService {
    private final ProductPort productPort;

    ProductService(final ProductPort productPort) {
        this.productPort = productPort;
    }

    public void addProduct(final AddProductRequest request) {
        final Product product = new Product(request.name(), request.price(), request.discountPolicy());

        productPort.save(product);
    }
}

 

ProductAdapter.java

package com.example.productorderservice.product;

import org.springframework.stereotype.Component;

@Component // 추가
class ProductAdapter implements ProductPort {
    private final ProductRepository productRepository;

    ProductAdapter(final ProductRepository productRepository) {
        this.productRepository = productRepository;
    }

    @Override
    public void save(final Product product) {
        productRepository.save(product);
    }
}

 

ProductRepository.java

package com.example.productorderservice.product;

import org.springframework.stereotype.Repository;

import java.util.HashMap;
import java.util.Map;

@Repository//추가
class ProductRepository {
    private Long sequence = 0L;
    private Map<Long, Product> persistence = new HashMap<>();

    public void save(final Product product) {
        product.assignId(++sequence);
        persistence.put(product.getId(), product);
    }
}

 

ProductServiceTest.java

package com.example.productorderservice.product;

import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;


@SpringBootTest // 추가
class ProductServiceTest {

    @Autowired // 추가
    private ProductService productService;

    @Test
    void 상품등록() {
        final AddProductRequest request = 상품등록요청_생성();
        productService.addProduct(request);
    }

    private static AddProductRequest 상품등록요청_생성() {
        final String name ="상품명";
        final int price = 1000;
        final DiscountPolicy discountPolicy = DiscountPolicy.NONE;
        return new AddProductRequest(name, price, discountPolicy);
    }


}
