• Junit加载Spring容器作单元测试


    阅读目录

    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);
        }
    
    }
