Testing with Spring and Maven: applicationContext

Question

Seems that question old as world, but I still can't find out the solution..

I'm trying to run simple test:

@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = {"/applicationContext.xml", "/PersonsPopulateTest-context.xml"}) @Transactional public class PersonsPopulateTest { 

Files are at:

src    main       resources            applicationContext.xml 

and

src            test       resources           PersonsPopulateTest-context.xml  

So after building these files are at target/classes and target/test-classes

But mvn test command still says: Failed to load ApplicationContext

What official docs say:

@RunWith(SpringJUnit4ClassRunner.class) // ApplicationContext will be loaded from "/applicationContext.xml" and "/applicationContext-test.xml" // in the root of the classpath @ContextConfiguration(locations={"/applicationContext.xml", "/applicationContext-test.xml"}) public class MyTest {     // class body... } 

Where did I go wrong?

Thanks, Vlaidimir

I think Maven simply didn't include the XML file from main/resources.

You could try to specify explicitly what to include in the pom.xml.

Let me know if the following configuration has worked:

    <!-- Add this directly after the <build>-opening tag -->     <resources>         <resource>             <filtering>true</filtering>             <directory>src/test/resources</directory>             <includes>                 <include>**/*.properties</include>             </includes>             <excludes>                 <exclude>**/*local.properties</exclude>             </excludes>         </resource>         <resource>             <directory>src/main/resources</directory>             <includes>                 <include>**/*.properties</include>                 <include>**/*.xml</include>             </includes>         </resource>     </resources> 

This is something I use in your case. You can edit this if you don't have properties files to be included.

Answer 2

My test context file is under src\test\resources\spring folder. I managed to load the context with

@ContextConfiguration(locations={"classpath:**/test-context.xml"}) 

But reference (in test-context.xml) to the application-context.xml which is under src\main\resources\spring folder failed

I managed to load the application-context by creating a ClassPathXmlApplicationContext in the test class with

ClassPathXmlApplicationContext appContext=new ClassPathXmlApplicationContext(new String[]{"classpath:spring/application-context.xml","classpath:spring/model-context.xml"}); 

Let me know if this helps or might create any other issues.
