JUNIT测试用例未通过

Question

I have class where I am written code to create a new category and if category not found it will throw "CategoryNotFoundException". I have written the test cases but it was not passed.

If I omit "expected= CategoryNotFoundException.class" from my JUNIT test case it will pass. But I don't want to change any portion in my Test cases. I tried by throwing the exception from my implemented class but still it is not passed.I am stucking there to pass the TestCase.

    DAO code::
    @Transactional
        public boolean createCategory(Category category){
            //boolean isInserted=false;

            Session session=this.sessionFactory.getCurrentSession();
            session.save(category);
            return true;

            //return isInserted;
        }

Tried with the below code as well but TC not passed:

   @Transactional
                public boolean createCategory(Category category){
                    //boolean isInserted=false;  
                try{            
                    Session session=this.sessionFactory.getCurrentSession();
                    Integer isInsertedWrapper=(Integer)session.save(category);
                    if(isInsertedWrapper>0){
                      return true;
                     }else{
                       throw new CategoryNotFoundException("CategoryNotFoundException");
    }
    }
    catch(Exception ex){
       return false;
    } 
}

JUNIT Code::

    @Test(expected= CategoryNotFoundException.class)
        @Rollback(true)
        public void testCreateCategoryFailure() throws CategoryNotFoundException {
            categoryDAO.createCategory(category);
            Category savedCategory = categoryDAO.getCategoryById(2);
            assertNotEquals(category, savedCategory);`enter code here`

        }

You are trying to throw an exception but you are catching also, so you should rethrow If it is necessary, so you should try to do this:

@Transactional
public boolean createCategory(Category category){
                //boolean isInserted=false;  
    try {            
         Session session=this.sessionFactory.getCurrentSession();

         Integer isInsertedWrapper=(Integer)session.save(category);

         if(isInsertedWrapper>0){
             return true;
         }else{
             throw new CategoryNotFoundException("CategoryNotFoundException");
         }
    } catch(CategoryNotFoundException exc) {
         throw exc;
    } catch(Exception ex){
         return false;
    } 
}
