在接下來的功能，我會需要一個可以幫我針對anki的modelName的不同，來進行指定的操作
所以現在會需要以下的規劃

1. 有個產生operator的generator，然後根據傳入的note來回傳相對應的operator
2. 根據operator的類型，來進行相對應的操作

因此會需要以下的interface

type OperatorGenerator interface {  
    GetByNote(note Note) (o Operator, err error)  
}

type Operator interface {  
    Do() error  
}

另外，也要針對目前的牌組設定相對應的Operator
我目前自己的牌組有三種

1. Japanese (recognition&recall)
2. Japanese (recognition&recall) 動詞篇
3. Japanese (recognition&recall) 形容詞

因此，也順應的產生了這三種struct

type NormalOperator struct {  
    Note Note  
}  
  
func (n *NormalOperator) Do() error {  
    //TODO implement me  
    panic("implement me")  
}  
  
type VerbOperator struct {  
    Note Note  
}  
  
func (v *VerbOperator) Do() error {  
    //TODO implement me  
    panic("implement me")  
}  
  
type AdjOperator struct {  
    Note Note  
}  
  
func (a *AdjOperator) Do() error {  
    //TODO implement me  
    panic("implement me")  
}

以及相對應的測試

func (t *AnkiOperationSuite) Test_get_correct_modal_type_operator() {  
    note := Note{  
       ModelName: "Japanese (recognition&recall)",  
    }  
    generator := OperatorGenerate{}  
    normalOperator, _ := generator.GetByNote(note)  
    _, ok := normalOperator.(*NormalOperator)  
    t.True(ok, "type is not *NormalOperator")  
  
    note = Note{  
       ModelName: "Japanese (recognition&recall) 動詞篇",  
    }  
    generator = OperatorGenerate{}  
    verbOperator, _ := generator.GetByNote(note)  
    _, ok = verbOperator.(*VerbOperator)  
    t.True(ok, "type is not *VerbOperator")  
  
    note = Note{  
       ModelName: "Japanese (recognition&recall) 形容詞",  
    }  
    generator = OperatorGenerate{}  
    adjOperator, _ := generator.GetByNote(note)  
    _, ok = adjOperator.(*AdjOperator)  
    t.True(ok, "type is not *AdjOperator")  
}
