django-nose nose-py3 unit test shows the string None in the output even when successful

Question

1. I have installed:

   django-nose==1.4.7
   nose-py3==1.6.3
   pinocchio==0.4.3

2. added django_nose to the INSTALLED_APPS

3. added the lines:

   TEST_RUNNER = 'django_nose.NoseTestSuiteRunner'
   NOSE_ARGS = ['--with-spec', '--spec-color']
   

   to the settings.py file in django

4. created the following unit tests:

   def test_run_creation(self):
       """Test if the creation of runs creates instances of the Run model."""
       self.assertIsInstance(self.run1, Run)
       self.assertIsInstance(self.run2, Run)
       self.assertIsInstance(self.run3, Run)
   
   def test_run_number_consistency(self):
       """Test if the number of runs in the project increases by 1 after run creation."""
       self.assertEqual(self.final_no_of_runs_in_project,
                        self.initial_no_of_runs_in_project + 1)
   

the test run successfully and produce the following output:

nosetests --with-spec --spec-color --with-xunit --verbosity=1
Creating test database for alias 'default'...

- Test if the creation of runs creates instances of the Run model.

None
- Test if the number of runs in the project increases by 1 after run creation.

I would like to replace the String None in the output with something more descriptive but i have no idea what generate that text. Can anyone please help?

Thank you
