[スプリングガイドとAWS単独で実施されるWebサービス]CHAPTER 2 HelloControllerとテストコードの学習

1.主クレーム

package com.hadoyaji.book.springboot;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.data.jpa.repository.config.EnableJpaAuditing;


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

2.Hello Controlとテストコード

package com.hadoyaji.book.springboot.web;

import com.hadoyaji.book.springboot.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 helloDto(@RequestParam("name") String name, @RequestParam("amount") int amount){
        return new HelloResponseDto(name,amount);

    }
}

import com.hadoyaji.book.springboot.config.auth.SecurityConfig;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.FilterType;
import org.springframework.security.test.context.support.WithMockUser;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;

import static org.hamcrest.Matchers.is;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;

@RunWith(SpringRunner.class)
@WebMvcTest(controllers = HelloController.class,
            excludeFilters = {
            @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, classes = SecurityConfig.class)
            })
public class HelloControllerTest {

    @Autowired
    private MockMvc mvc;

    @WithMockUser(roles="USER")
    @Test
    public void hello_가_리턴된다() throws Exception{
            String hello = "hello";

            mvc.perform(get("/hello"))
                    .andExpect(status().isOk())
                    .andExpect(content().string(hello));
    }

    @WithMockUser(roles = "USER")
    @Test
    public void helloDto가_리턴된다() throws Exception{
        String name = "hello";
        int amount = 1000;

        (mvc.perform(get("/hello/dto").param("name", name).param("amount",String.valueOf(amount))))
                .andExpect(status().isOk())
                .andExpect(jsonPath("$.name",is(name)))
                .andExpect(jsonPath("$.amount",is(amount)));
    }

}

3.lombokのHelloResponseDtoとテストコードを適用する

import lombok.Getter;
import lombok.RequiredArgsConstructor;

@Getter
@RequiredArgsConstructor
public class HelloResponseDto {

    private final String name;
    private final int amount;
}

import org.junit.Test;

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

public class HelloResponseDtoTest {

    @Test
    public void 롬복_기능_테스트(){
        //given
        String name = "test";
        int amount = 1000;

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

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