JUnit 单元测试启动 Spring 容器

http://blog.csdn.net/qq_18416057/article/details/53409722

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：

 

[html] view plain copy

print?

1. <dependency>  
2.             <groupId>junit</groupId>  
3.             <artifactId>junit</artifactId>  
4.             <version>4.4</version>  
5.         </dependency>  
6.         <dependency>  
7.             <groupId>org.springframework</groupId>  
8.             <artifactId>spring-test</artifactId>  
9.             <version>2.5</version>  
10.         </dependency>  

<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>

 

[java] view plain copy

print?

1. <dependency>  
2.     <groupId>org.springframework</groupId>  
3.     <artifactId>spring-test</artifactId>  
4.     <version>3.1.1.RELEASE</version>  
5. </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。

[java] view plain copy

print?

1. @RunWith(SpringJUnit4ClassRunner.class)    
2. @ContextConfiguration(locations ={“/applicationContext.xml”})    
3. public class ProducerConsumerTest {  
4.    
5.     @Autowired  
6.     private Sender sender;  
7.     @Autowired  
8.     @Qualifier(“queueDestination”)  
9.     private Destination destination;  
10.       
11.    @Test  
12.     public void testSend() {  
13.         for (int i=0; i<2; i++) {  
14.          sender.sendInfo(destination, ”你好，生产者！这是消息：” + (i+1));  
15.         }  
16.     }  
17.       
18. }  

@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));        }    }    }

[java] view plain copy

print?

1. @RunWith(SpringJUnit4ClassRunner.class)  
2. @ContextConfiguration({“classpath:applicationContext.xml”})  
3. public class ReadDaoImplTest {  
4.     @Resource ReadDao readDao;  
5.       
6.     @Test  
7.     public void getListTest(){  
8.         List<Client> clientList = readDao.getList(”client.test”, null);  
9.           
10.         for(Client c:clientList){  
11.             System.out.println(c.getVersionNum());  
12.         }  
13.     }  
14. }  

@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

 

[java] view plain copy

print?

1. public class ReadDaoImplTest {  
2.       
3.     public  static void main(String[] args){  
4.         ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(“applicationContext.xml”);  
5.   
6.         context.start();  
7.   
8.         ReadDao fqaService = (ReadDao) context.getBean(”readDao”);  
9.         System.out.println(fqaService);  
10.     }  
11.       
12. }  

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);    }}

 

[java] view plain copy

print?

1. public class ReadDaoImplTest {  
2.       
3.     public  static void main(String[] args){  
4.         ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(“applicationContext.xml”);  
5.   
6.         context.start();  
7.   
8.         ReadDao fqaService = (ReadDao) context.getBean(”readDao”);  
9.         System.out.println(fqaService);  
10.     }  
11.       
12. }  

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。
