Python unit testing Class properties

I am trying to figure out if there's a way to (unit test) verify that the property and the setter is actually called to set the name attribute.

class DummyName:
    def __init__(self):
        self.name = ''

    @property
    def name(self):
        return self.name

    @name.setter
    def name(self, name):
        if not isinstance(name, basestring):
            raise Exception('Name must be a string.')
        self.name = name

Trying to do something like this...

@mock.patch.object(DummyName, 'name', new_callable=PropertyMock)
def testNameProperty(self, mock_name):
    MockName = Mock()
    mock_name.return_value = MockName
    dummyName = DummyName()
    dummyName.name = 'test_name'
    # assert setter is called to set the name
    # assert name is called to get the name
    # assert name is 'test_name'

Seems like name() and setter are never accessed. the Anyone has a better idea? Thanks!
