Solve the following python programming problem given the following code:
def _test_cinder_add(self, fake_volume, volume_file, size_kb = 5, verifier = None) : 
    expected_image_id = str (uuid.uuid4 ()) 
    expected_size = (size_kb * units.Ki) 
    expected_file_contents = (b'*' * expected_size) 
    image_file = six.BytesIO (expected_file_contents) 
    expected_checksum = hashlib.md5 (expected_file_contents).hexdigest () 
    expected_location = ('cinder://%s' % fake_volume.id) 
    fake_client = FakeObject (auth_token = None, management_url = None) 
    fake_volume.manager.get.return_value = fake_volume 
    fake_volumes = FakeObject (create = mock.Mock (return_value = fake_volume)) 
    @ contextlib.contextmanager 
    def fake_open(client, volume, mode) : 
        self.assertEqual (mode, 'wb') 
        (yield volume_file) 
with mock.patch.object (cinder, 'get_cinderclient') as mock_cc, mock.patch.object (self.store, '_open_cinder_volume', side_effect = fake_open) : 
        mock_cc.return_value = FakeObject (client = fake_client, volumes = fake_volumes) 
        (loc, size, checksum, _) = self.store.add (expected_image_id, image_file, expected_size, self.context, verifier) 
        self.assertEqual (expected_location, loc) 
        self.assertEqual (expected_size, size) 
        self.assertEqual (expected_checksum, checksum) 
        fake_volumes.create.assert_called_once_with (1, name = ('image-%s' % expected_image_id), metadata = { 
            'image_owner' : fake_volumes.context.tenant, 
            'glance_image_id' : expected_image_id, 
            'image_size' : str (expected_size), 
})
