Solve the following python programming problem given the following code:
def test_all_actions_must_be_rolled_back_on_failure(self) : 
    before_rollback = MagicMock () 
    command_rollback = MagicMock () 
    after_rollback = MagicMock () 
    class RollbackTestCommand (NamedCommand) : 
        def __init__(self, lizy) : 
            super (RollbackTestCommand, self).__init__ (lizy, 'rollback desc', command_rollback) 
def _process_command(self, lizy, args) : 
            return None 
class B (BeforeTask) : 
        def __init__(self) : 
            super (B, self).__init__ (before_rollback) 
            self.enable_rollback (before_rollback) 
def execute(self, lizy, args) : 
            pass 
class A (AfterTask) : 
        def __init__(self) : 
            super (A, self).__init__ (after_rollback) 
            self._needs_rollback = True 
def execute(self, lizy, args) : 
            raise PyleaseError () 
subparser_mock = (lambda : 0) 
    subparser_mock.add_parser = MagicMock () 
    args_mock = (lambda : 0) 
    args_mock.verbose = False 
    info_container = InfoContainer () 
    info_container.is_empty = False 
    lizy = Pylease (None, subparser_mock, args_mock) 
    command = RollbackTestCommand (lizy) 
    command.add_before_task (B ()) 
    command.add_after_task (A ()) 
    command (args_mock) 
    before_rollback.assert_called_once_with ()
