Solve the following python programming problem given the following code:
@ mock.patch.object (time, 'sleep') 
def test_init_db_error(self, mock_sleep) : 
    class TestCellStateManagerDB (state.CellStateManagerDB) : 
        def __init__(self) : 
            self._cell_data_sync = mock.Mock () 
            self._cell_data_sync.side_effect = [db_exc.DBError (), []] 
            super (TestCellStateManagerDB, self).__init__ () 
test = TestCellStateManagerDB () 
    mock_sleep.assert_called_once_with (30) 
    self.assertEqual (2, self._cell_data_sync.call_count) 

    
    

    Fix the buggy line: self.assertEqual (2, self._cell_data_sync.call_count)

#Here is Python program to fix the buggy line: self.

self.assertEqual (2, test._cell_data_sync.call_count)
