I’m trying to use the @Test(expected = RuntimeException.class) annotation in
order to test for an expected exception. My code is as follows: 

@Test(expected = RuntimeException.class)
    public void testSaveThrowsRuntimeException(){

                    User user = domain.save(null);

    }

and my save method simple like this :

public User save(User newUser) { 
         if(newUser == null) { 
            throw new RuntimeException(); 
         }
         //saving code goes here
    }

after debugging the code I found that code throwing the exception as expected but its getting eaten somewhere in between in spring framework classes.

I tried the same with old way (try catch block) but still I am not able to catch that exception in test and test keeps throwing errors in runafter method of Junit :

And I am sure this is because of that RuntimeException I am throwing in save but not able catch it or pass the test with expected clause.

anybody have any idea whats going wrong?

    Here’s a work-around I found to with Junit 4.5 – separate the @Transactional and @ExpectedException into nested functions.
    I guess the problem is something to do with the aop stuff spring puts around a @Transactional method. 

    @Test
@ExpectedException(org.springframework.dao.DataIntegrityViolationException.class)
public void Test10UniqueName()
{
    DoTest10UniqueName();
}

@Transactional
public void DoTest10UniqueName()
{
    final String NAME = "NAME";
    ProductCategoryDAO dao = DAOFactory.getProductCategoryDAO();
    ProductCategory test1 = new ProductCategory();
    test1.setName(NAME);
    ProductCategory test2 = new ProductCategory();
    test2.setName(NAME);
    dao.save(test1);
    dao.save(test2);
}
