關鍵字'Zerocon'預計有0個參數，得到6個

Question

這是一個機器人腳本。

這是設置。

*** Settings *** 
    Suite Setup GetUrl 
    Test Setup  Create HTTP Context ${conturl[0]["Host"]} 
    Library JsonLibb.py 
    Library RequestsLibrary 
    Library HttpLibrary.HTTP 

這是測試用例。

*** Test Cases *** 
    Msg 
     Log ${con} 
     Run Keyword If ${con}==1 Zerocon Onecon 
      ELSE If ${con}==2 Zerocon Onecon Twocon 
      ELSE Log 'Error' 

這是關鍵字。

Answer 1

這是測試用例。

*** Test Cases *** 
    Msg 
     Log ${con} 
     Run Keyword If ${con}==1 Zerocon Onecon 
      ELSE If ${con}==2 Zerocon Onecon Twocon 
      ELSE Log 'Error' 

Answer 2

第一個問題是ELSE If必須是ELSE IF。從文檔中（重點添加）：

從Robot 2.7.4版開始，此關鍵字還支持可選的ELSE和ELSE IF分支。上述這些問題都在* ARGS定義和必須使用完全相同的格式ELSE或ELSE IF

你有一樣的錯誤說，另一個問題是，Zerocon好好嘗試一下帶任何參數，但你傳遞參數到它。你傳遞的是看起來是關鍵字名稱的東西，但我不知道你期望會發生什麼。我不知道你是否想要運行這些關鍵字，或將它們作爲參數傳遞給Zerocon。
