介绍在 spring 的框架下，做单元 测试 的两种办法。

    一、使用spring中对Junit框架的整合功能

    除了junit4和spring的jar包，还需要spring-test.jar。引入如下依赖：

 

<dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.4</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>2.5</version>
        </dependency>

 

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <version>3.1.1.RELEASE</version>
</dependency>

    @ContextConfiguration需要配上spring的配置文件，这样就可以在测试类中使用注解简单的注入需要的bean了。简单高效。

@RunWith(SpringJUnit4ClassRunner.class)  
@ContextConfiguration(locations ={"/applicationContext.xml"})  
public class ProducerConsumerTest {
 
    @Autowired
    private Sender sender;
    @Autowired
    @Qualifier("queueDestination")
    private Destination destination;
    
   @Test
    public void testSend() {
        for (int i=0; i<2; i++) {
         sender.sendInfo(destination, "你好，生产者！这是消息：" + (i+1));
        }
    }
    
}

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:applicationContext.xml"})
public class ReadDaoImplTest {
    @Resource ReadDao readDao;

    @Test
    public void getListTest(){
        List<Client> clientList = readDao.getList("client.test", null);

        for(Client c:clientList){
            System.out.println(c.getVersionNum());
        }
    }
}

    二、手动加载spring的配置文件，并启动spring容器

 

public class ReadDaoImplTest {

    public  static void main(String[] args){
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");

        context.start();

        ReadDao fqaService = (ReadDao) context.getBean("readDao");
        System.out.println(fqaService);
    }

}

 

public class ReadDaoImplTest {

    public  static void main(String[] args){
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");

        context.start();

        ReadDao fqaService = (ReadDao) context.getBean("readDao");
        System.out.println(fqaService);
    }

}

    运行这两种测试方法，EclipseIDE下都只需要Ctrl+F11。
