Solve the following python programming problem given the following code:
def test_command_must_execute_before_tasks_before_self_execution(self) : 
    class SuccessCommand (NamedCommand) : 
        def __init__(self, lizy) : 
            super (SuccessCommand, self).__init__ (lizy, 'desc') 
def _process_command(self, lizy, args) : 
            return (None, None) 
before = MagicMock () 
    after = MagicMock () 
    lizy = MagicMock () 
    args = MagicMock () 
    info_container = InfoContainer () 
    info_container.is_empty = False 
    lizy.info_container = info_container 
    sc = SuccessCommand (lizy) 
    sc.add_before_task (before) 
    sc.add_after_task (after) 
    sc (args) 
    before.assert_called_once_with (self, args) 
    after.assert_called_once_with (lizy, args) 

    
    

    Fix the buggy line: before.assert_called_once_with (self, args)

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