Introduction to various methods of Spring Test in Config

This article mainly introduces relevant information about the Spring Test method example code under Java Config. Friends in need can refer to

Spring Test method under Java Config

Three methods are used:

1. Purely manual bean fetching:

package com.wang.test;

import com.marsmother.commission.core.config.MapperConfig;
import com.marsmother.commission.core.config.PropertyConfig;
import com.marsmother.commission.core.config.ServiceConfig;
import com.marsmother.commission.core.dto.GeneralResponseData;
import com.marsmother.commission.core.service.UserService;
import com.marsmother.commission.site.config.SecurityConfig;
import org.junit.Before;
import org.junit.Test;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;

/**
 * Created by Wanglei on 15/10/29.
 */
public class CustomeTest {

  private static AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext();

  @Before
  public void tearUp(){
    context.register(PropertyConfig.class);
    context.register(ServiceConfig.class);
    context.register(SecurityConfig.class);
    context.register(MapperConfig.class);
    context.refresh();
  }

  @Test
  public void testUser(){
    UserService userService = context.getBean(UserService.class);
    Long userId = 3L;
    GeneralResponseData data = userService.addUserRelation(userId);
    System.out.println(data.getMsg());
  }
}

2. Use spring-test

package com.wang.test;

import com.marsmother.commission.core.config.MapperConfig;
import com.marsmother.commission.core.config.PropertyConfig;
import com.marsmother.commission.core.config.ServiceConfig;
import com.marsmother.commission.core.dto.GeneralResponseData;
import com.marsmother.commission.core.service.UserService;
import com.marsmother.commission.site.config.SecurityConfig;
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.context.junit4.SpringJUnit4ClassRunner;

/**
 * Created by Wanglei on 15/10/29.
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {PropertyConfig.class, ServiceConfig.class, SecurityConfig.class, MapperConfig.class})
public class SpringTest {

  @Autowired
  private UserService userService;

  @Test
  public void testUser(){
    GeneralResponseData data= userService.addUserRelation(3L);
    System.out.println(data.getMsg());
  }

}

3. Use Mockito

You need to introduce the corresponding package:

<dependency>
  <groupId>org.mockito</groupId>
  <artifactId>mockito-all</artifactId>
  <version>1.9.5</version>
  <scope>test</scope>
</dependency>

package com.wang.test;

import com.marsmother.commission.core.dto.GeneralResponseData;
import com.marsmother.commission.core.presistence.FollowNumberMapper;
import com.marsmother.commission.core.presistence.UserMapper;
import com.marsmother.commission.core.presistence.UserRelationMapper;
import com.marsmother.commission.core.service.UserService;
import org.junit.Before;
import org.junit.Test;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;

/**
 * Created by Wanglei on 15/10/29.
 */
public class TestUserService {

  @InjectMocks
  private UserService userService;

  @Mock
  private FollowNumberMapper followNumberMapper;
  @Mock
  private UserMapper userMapper;
  @Mock
  private UserRelationMapper userRelationMapper;

  @Before
  public void init(){
    MockitoAnnotations.initMocks(this);
  }

  @Test
  public void testUser(){
    Long userId = 3L;
    GeneralResponseData result = userService.addUserRelation(userId);
    System.out.println(result.getMsg());
  }

}

Here@Mock If so, it will not actually perform database operations.

There is another usage called @Spy. I don’t know the specific usage yet and need to study it.

In comparison, spring-test is more standard.
