Question

I want to create test data at runtime for my junit test cases. As part of that activity i have choose to write a set of data fixtures and an implementation around it which would create/remove/update test data. These would be called from every Junit class @before and @After methods – @before to setup the test data and @after to teardown the test data.

I have written all this implementation inside the “test” package and have marked the main classes as @component and @autowired these new classes. However when i run my junit test it is unable to create the instances of these new classes and hence the autowire does not seem to work.

I am not sure what more i have to do prior to autowire other than adding following configuration inside the test-config.xml

<context:component-scan base-package="test">
</context:component-scan>

I am using Spring 3.x and Junit 4.

//Business implementation:

//File location: src/main/java/com/abc/prq

package com.abc.pqr

@Service("myservice")
public class MyService{

}

//Junit Test for Myservice class:

//File Location: src/test/java/com/abc/pqr

 package com.abc.pqr;
 @RunWith(SpringJUnit4ClassRunner.class)
 @ContextConfiguration(locations={"classpath:/META-INF/spring/test-Config.xml"})
 public class MyServiceTest {
     @Autowired  
     private ABC abc;
 }

//Data Fixture to create/remove/update test data

//File Location: src/test/java/com/abc/pqr/datafixtures

 package com.abc.pqr.datafixtures
 @Component("abc") 
 public class ABC{
     public void create(){
     } 
     public void remove(){
     } 
     public void update(){
     }
 }

I think that the problem is caused by the fact that you’re not scanning the right package in the spring test context.
The test-Config.xml file should look something like this:

<context:annotation-config />
<context:component-scan base-package="com.abc.pqr.datafixtures" /> 

Hope this helps.
