Junit4测试Service中的方法

1.添加pom依赖，如下两个依赖：

<dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
            <scope>test</scope>
        </dependency>

<dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>4.1.7.RELEASE</version>
            <scope>test</scope>
        </dependency>

2.创建测试类，范例如下：

package com.iborch.health.service.user;

import com.iborch.health.dao.entity.User;
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;
import javax.annotation.Resource;
import static org.junit.Assert.*;

/**
 * Created by lhp on 2017/9/4.
 */
@RunWith(SpringJUnit4ClassRunner.class)//指定执行类
@ContextConfiguration(locations = {"classpath*:spring-servlet.xml"})
//加载配置，将测试置于spring环境当中
public class UserServiceImplTest {

    @Autowired
    UserService userService;

    @Resource
    UserMapper userMapper;

   @Before
    public void setUp() throws Exception {
    }
  
    @Test
    public void searchById() throws Exception {
        User user = userService.searchById("029a34aa-b90a-47bb-acba-47362fd29d69");
        System.out.println("测试的结果：返回用户的姓名："+user.getName());
        assertEquals("dap3533", user.getName());
    }
}

3.批量执行测试类，找个包建如下类，右键运行，就实现了，@Suite.SuiteClasses({UserServiceImplTest.class})这个注解配置要执行的测试类，多个测试类之间用逗号隔开。

范例：

package com.iborch.health.service.user;

import org.junit.runner.RunWith;
import org.junit.runners.Suite;

/**
 * Created by lhp on 2017/9/5.
 */
@RunWith(Suite.class)
@Suite.SuiteClasses({UserServiceImplTest.class})
public class RunTest {
//没有任何的逻辑代码，为空​
}
