[스프링 부트] 테스트 - spring-boot-starter-test

mock을 이용한 간단한 테스트를 진행해 보자

    @Test

        mockMvc.perform(get("/hello"))
                .andExpect(status().isOk())
                .andExpect(content().string("hello hongjun"))
                .andDo(print());
    }

SpringBootTest의 WebEnviroment를 RANDOM_PORT로 지정하여 실제 servlet를 이용한 테스트를 진행해 보자.

package com.hongjun423.springinit.sample;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.boot.test.web.client.TestRestTemplate;
import org.springframework.test.context.junit4.SpringRunner;

import static org.assertj.core.api.Assertions.assertThat;
import static org.mockito.Mockito.when;

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@AutoConfigureMockMvc
public class SampleControllerTest {

    @Autowired
    TestRestTemplate testRestTemplate;

    @MockBean
    SampleService mockSampleService;

    @Test
    public void hello() {
        when(mockSampleService.getName()).thenReturn("hongjun");

        String result = testRestTemplate.getForObject("/hello", String.class);
        assertThat(result).isEqualTo("hello hongjun");
    }
}
