idea intellij to unit test Spring

1. Add Junit4 and SpringJUnit4 support

1. <!-- junit -->  
2. <dependency>  
3.             <groupId>junit</groupId>  
4.             <artifactId>junit</artifactId>  
5.             <scope>test</scope>  
6.         </dependency>  
7.   
8. <!-- spring-test -->  
9.  <dependency>  
10.         <groupId>org.springframework</groupId>  
11.         <artifactId>spring-test</artifactId>  
12.     </dependency>  

2. Create a test class

(wins: right-click menu -------> Go to (G) -------> Test (E) to quickly create a corresponding test class in the test package and the same directory)

(ios: IntelliJ IDEA provides a shortcut Cmd + Shift + T as a navigation between classes and tests. Also allows users to create a test class there.)

 

3. The generated code is as follows:

1. package net.wll.web.service.impl;  
2.   
3. import org.junit.Test;  
4.   
5. import static org.junit.Assert.*;  
6.   
7. public class DAreasServiceImplTest {  
8.   
9.     @Test  
10.     public void testSelectSubDistricts() throws Exception {  
11.   
12.     }  
13.   
14.     @Test  
15.     public void testSelectSubDistricts0() throws Exception {  
16.   
17.     }  
18. }  

4. Add Spring-test support

1. package net.xuele.activity.service.impl;  
2.   
3. import net.xuele.activity.domain.DAreas;  
4. import net.xuele.activity.service.DAreasService;  
5. import org.junit.Test;  
6. import org.junit.runner.RunWith;  
7. import org.springframework.test.context.ContextConfiguration;  
8. import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;  
9. import javax.annotation.Resource;  
10. import java.util.List;  
11.   
12. @RunWith(SpringJUnit4ClassRunner.class)  
13. /** Inject related configuration files: multiple configuration files can be written **/  
14. @ContextConfiguration(locations={"classpath:META-INF/spring/application-services.xml",  
15.         "classpath:META-INF/spring/applicationContext-persist.xml"  
16. })  
17. public class DAreasServiceImplTest {  
18.     @Resource  
19.     private DAreasService dAreasService;  
20.   
21.     @Test  
22.     public void testSelectSubDistricts0() throws Exception {  
23.         List<DAreas> dAreases =  this.dAreasService.selectSubDistricts0();  
24.         System.out.println(dAreases.size());  
25.     }  
26. }
