Spring MVC 테스트코드 작성하기

Spring MVC 테스트코드를 작성해보자.

1. 의존성 추가

junit을 사용하기 위해서 pom.xml에 의존성을 추가한다.

<!-- junit & spring-test -->
<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>compile</scope>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <version>3.2.3.RELEASE</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <version>3.2.3.RELEASE</version>
    <scope>compile</scope>
</dependency>

2. 프로젝트가 JNDI를 사용하는 경우

JUnit을 이용한 스프링 단위테스트시에 SpringJUnit4ClassRunner 클래스를 사용하는데 JNDI를 사용하는 경우 서버 정보가 WAS에 있으므로 별도의 서버 정보를 가져오는 클래스를 만들어서 사용한다.

public class ExtSpringJUnit4ClassRunner extends SpringJUnit4ClassRunner {
    public ExtSpringJUnit4ClassRunner(Class<?> clazz) throws InitializationError {
        super(clazz);
        // TODO Auto-generated constructor stub
        try {
            bindJndi();
        } catch (Exception e) {

        }
    }

    private void bindJndi() throws Exception {
        SimpleNamingContextBuilder builder = new SimpleNamingContextBuilder();
        builder.activate();

        JndiTemplate jt = new JndiTemplate();

        DriverManagerDataSource ds = new DriverManagerDataSource();
        ds.setDriverClassName(...);
        ds.setUrl(...);
        ds.setUsername(...);
        ds.setPassword(...);

        jt.bind("java:/../../../..", ds);
    }
}

3. 테스트 코드 작성

ExtSpringJUnit4ClassRunner 클래스를 사용한다.

applicationContext를 불러온다.

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

@RunWith(ExtSpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
        "applicationContext.xml"
})
public class MainControllerTest {

    @Autowired
    MainController mainController;

    private MockMvc mockMvc;

    @Before
    public void setUp() throws Exception {
        mockMvc = MockMvcBuilders.standaloneSetup(mainController).build();
    }

    @Test
    public void mainControllerTest() throws Exception {
        mockMvc.perform(get("/main"))
                .andDo(print())
                .andExpect(status().isOk());
    }
}

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.transaction.annotation.Transactional;
import static org.junit.Assert.*;


@RunWith(ExtSpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
        "classpath:/egovframework/spring/com/context-*.xml",
        "classpath:/egovframework/spring/com/idgn/context-*.xml",
        "file:src/main/webapp/WEB-INF/config/egovframework/springmvc/egov-com-*.xml"
})
public class MemberDaoTest {

    @Autowired
    MemberDAO dao;

    @Autowired
    MemberService service;

    @Test
    public void 회원조회_테스트() throws Exception {
        MemberVO vo = new MemberVO();
        vo.setMemberId("qwerty123@email.com");
        MemberVO selectedMember = service.selectSetMember(vo);
        assertEquals(selectedMember.getMemberId(), vo.getMemberId());
    }

    @Test
    @Transactional
    public void 회원수정_테스트() throws Exception {
        MemberVO member = new MemberVO();
        member.setMemberId("qwerty123@email.com");
        member.setPwMiscnt(1);
        service.updateMemeberPwMisCnt(member);
        assertEquals(1, service.selectSetMember(member).getPwMiscnt());
    }
}
