Correct Test Considered as Error with nosetests

I use the package parameterized(by wolever) withnosetests. I built the following packages and modules with Python 3 :

src 
 |__utils
 |     |_kwargs.py
 |     |_exceptions.py
 |

tests
 |__test_kwargs.py

In test_kwargs.py, I try to test custom exceptions from exceptions.py. In the following case, I test if the function correct_kwargs occurs a ValueNotMatchOption exception. But it seems to be a problem of package or a hierarchy of modules :

Function :

def test_Test_KwargsException(self,_,oracle_test,test):
    assert_raises(ValueNotMatchOption,is_correct_kwargs(oracle_test,test))

Error :

 ils/check_kwargs.py", line 27, in is_correct_kwargs
 raise ValueNotMatchOption("ggd")
      src.utils.exceptions.ValueNotMatchOption: ggd

Thanks.
