【Spring】Junit加载Spring容器作单元测试

如果我们需要对我们的Service方法作单元测试,恰好又是用Spring作为IOC容器的,我们可以这么配置Junit加载Spring容器,方便做单元测试。

 

> 基本的搭建

(1)引入所需的包

<dependency>    <groupId>junit</groupId>    <artifactId>junit</artifactId>    <version>3.8.1</version>    <scope>test</scope></dependency><dependency>    <groupId>org.springframework</groupId>    <artifactId>spring-test</artifactId>    <version>3.2.10.RELEASE</version></dependency>

 

(2)写测试类

测试类中要设置加载哪些Spring的配置(我这里是“/config/application*.xml”),然后就可以注入容器中的bean了。

package com.nicchagil.mybatis3spring3intg.junit;import java.util.List;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 com.nicchagil.mybatis3spring3intg.bean.User;import com.nicchagil.mybatis3spring3intg.service.UserService;@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration({"/config/application*.xml"})public class JunitTest {        @Autowired    private UserService userService;        @Test    public void c1() {        List<User> userList = userService.query(new User());        System.out.println(userList);    }}

 

> 常见的用法

常用的方式是将加载配置的部分公用出来:

package com.nicchagil.mybatis3spring3intg.junit;import org.junit.runner.RunWith;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration({"/config/application*.xml"})public class BaseJunit {    }

 

然后需要的各个测试类继承公用类:

package com.nicchagil.mybatis3spring3intg.junit;import java.util.List;import org.junit.Test;import org.springframework.beans.factory.annotation.Autowired;import com.nicchagil.mybatis3spring3intg.bean.User;import com.nicchagil.mybatis3spring3intg.service.UserService;public class UserServiceTest extends BaseJunit {        @Autowired    private UserService userService;        @Test    public void c1() {        List<User> userList = userService.query(new User());        System.out.println(userList);    }}
