Failed to load ApplicationContext while running test cases

Question

when i am running my spring integration junit class i am getting above exception.

here is my class

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext.xml")
public class BpmControllerTest {

    @Autowired
   private BpmProcessorDaoImplTest bpmProcessorDao;  

    @Test
    public void testRun() throws UnexpectedInputException, ParseException, NonTransientResourceException, Exception {
    List<User>user=bpmProcessorDao.testRead();
     Assert.assertEquals(0,user.size());

    }
   }

i have my applicationContext inside web-inf and i am using all the spring 4.x jars.

here is my stack trace..

Caused by: java.io.FileNotFoundException: class path resource [applicationContext.xml] cannot be opened because it does not exist
    at org.springframework.core.io.ClassPathResource.getInputStream(ClassPathResource.java:172)
    at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:330)
    ... 37 more

can any body please tell me how to write this line

@ContextConfiguration(locations = "classpath:applicationContext.xml")

some places in google i found like this

@ContextConfiguration(locations = "classpath:**/applicationContext.xml")

what is the difference of these two and when i am writing this line with stars i am getting different exception

here is my stack trace.

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.tcs.test.dao.BpmProcessorDaoImplTest] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

and one thing that my application is only dynamic web project no maven,no ant . can any body please tell me how to run my test cases successfully..

here is my applicationContext.

Does your applicationContext.xml have a bean definition for the BpmProcessorDaoImplTest? — Ben Green

In which folder is your applicaitonContext.xml... Is it by any change /WEB-INF? If so that isn't part of the classpath. — M. Deinum

1)

i have my applicationContext inside web-inf and i am using all the spring 4.x jars.

The web-inf folder is not (without hacks and problems) accessabel while running the tests.

So the short and easy solution is to put that spring config files in:

(if you use maven): src\main\resources
(if you do not use maven): your java source file root folder
(if you do not use maven but eclipse): create an extra folder (for example resources), put the files in that folder, and then make this folder a eclipse source folder (right click that folder in the package explorer and then choose "Build Path" / "Use as Source Folder")

2) your BpmProcessorDaoImplTest does not look like a valid test for me.

Either it is a Test case - then its methods have @Test annotations and the class itself have the @ContextConfiguration configuration that points to your configuration file. Or is is a Repository then it has a @Repository annotation and not @Test or @ContextConfiguration. annotations. But I never saw a class that mixed this.

So try this:

@ContextConfiguration("classpath:applicationContext.xml")
@Transactional //make your tests run in an transaction that gets rolled back after the test
public class BpmProcessorDaoImplTest {

   /** Class under test */
   @Autowired
   private BpmProcessorDao dbmProcessorDao;

   @Autowired
   JdbcTemplate jdbcTemplate;

   @Autowired
   private ResourceBundleMessageSource messageSource;

   //just to make the example test usefull
   @PersistenceContext
   private EntityManager em

   @Test
   public void testWrite() {

      DbmProcessor entity = ...;
      ...
      this.dbmProcessorDao.save();
      ...
      em.flush();  //make sure that every is saved before clear
      em.clear();  //clear to make read(id) read the entity from the database but not from l1-cache.
      int id = entity.getId();          
      ...

      DbmProcessor reloadedEntity = this.dbmProcessorDao.read(id);

      //getName is just an example
      assertEquals(entity.getName(), dbmProcessorDao.getName());
   }
}

thanks you very much for your reply now i am got getting any exception. but here in my dao class jdbc template and message resource classes are null that means spring is not creating object for that classes.

Ralph Over a year ago

Ist is likely that you need to copy the other configration files too.

suri Over a year ago

i have only one configuration file

Ralph Over a year ago

@suri - your test case looks strange, have a look at the second part of my answer.

This will occure when applicationContext.xml cannot be found in class path

Possible solutions :

add directory containing applicationContext.xml to classpath.
give relative path of applicationContext.xml
give absolute path of applicationContext.xml

If 3rd solution worked for you would mean that applicationContext.xml was not in classpath.
