[java] Spring @ContextConfiguration how to put the right location for the xml

In our project we are writting a test to check if the controller returns the right modelview

@Test
    public void controllerReturnsModelToOverzichtpage()
    {
        ModelAndView modelView = new ModelAndView();
        KlasoverzichtController controller = new KlasoverzichtController();
        modelView = controller.showOverzicht();

        assertEquals("Klasoverzichtcontroller returns the wrong view ", modelView.getViewName(), "overzicht");
    }

This returns the exception null.

We are now configuring the @contextconfiguration but we don't know how to load the right xml who is located at src\main\webapp\root\WEB-INF\root-context.xml

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
public class TestOverzichtSenario{
....

This documentation isn't clear enough to understand

Any suggestion on how to make sure the contextannotation loads the right xml?

Edit v2

I copied the configuration .xml files from the webINF folder to

src\main\resources\be\..a bunch of folders..\configuration\*.xml 

and changed the web.xml in webinf to

<param-name>contextConfigLocation</param-name>
<param-value>
            classpath*:configuration/root-context.xml
            classpath*:configuration/applicationContext-security.xml
        </param-value>

and now get the error

We Use:

@ContextConfiguration(locations="file:WebContent/WEB-INF/spitterMVC-servlet.xml")

the project is a eclipse dynamic web project, then the path is:

{project name}/WebContent/WEB-INF/spitterMVC-servlet.xml

Our Tests look like this (using Maven and Spring 3.1):

@ContextConfiguration
(
  {
   "classpath:beans.xml",
   "file:src/main/webapp/WEB-INF/spring/applicationContext.xml",
   "file:src/main/webapp/WEB-INF/spring/dispatcher-data-servlet.xml",
   "file:src/main/webapp/WEB-INF/spring/dispatcher-servlet.xml"
  }
)
@RunWith(SpringJUnit4ClassRunner.class)
public class CCustomerCtrlTest
{
  @Resource private ApplicationContext m_oApplicationContext;
  @Autowired private RequestMappingHandlerAdapter m_oHandlerAdapter;
  @Autowired private RequestMappingHandlerMapping m_oHandlerMapping;
  private MockHttpServletRequest m_oRequest;
  private MockHttpServletResponse m_oResp;
  private CCustomerCtrl m_oCtrl;

// more code ....
}

Simple solution is

@ContextConfiguration(locations = { "file:src/main/webapp/WEB-INF/applicationContext.xml" })

from spring forum

Sometimes it might be something pretty simple like missing your resource file in test-classses folder due to some cleanups.

This is a maven specific problem I think. Maven does not copy the files form /src/main/resources to the target-test folder. You will have to do this yourself by configuring the resources plugin, if you absolutely want to go this way.

An easier way is to instead put a test specific context definition in the /src/test/resources directory and load via:

@ContextConfiguration(locations = { "classpath:mycontext.xml" })

Suppose you are going to create a test-context.xml which is independent from app-context.xml for testing, put test-context.xml under /src/test/resources. In the test class, have the @ContextConfiguration annotation on top of the class definition.

@ContextConfiguration(locations = "/test-context.xml")
public class MyTests {
    ...
}

Spring document Context management

@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations = {"/Beans.xml"}) public class DemoTest{}

Loading the file from: {project}/src/main/webapp/WEB-INF/spring-dispatcher-servlet.xml

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "file:src/main/webapp/WEB-INF/spring-dispatcher-servlet.xml" })     
@WebAppConfiguration
public class TestClass {
    @Test
    public void test() {
         // test definition here..          
    }
}
