关键字'Zerocon'预计有0个参数，得到6个

Question

这是一个机器人脚本。

这是设置。

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

这是测试用例。

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

这是关键字。

Answer 1

这是测试用例。

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

Answer 2

第一个问题是ELSE If必须是ELSE IF。从文档中（重点添加）：

从Robot 2.7.4版开始，此关键字还支持可选的ELSE和ELSE IF分支。上述这些问题都在* ARGS定义和必须使用完全相同的格式ELSE或ELSE IF

你有一样的错误说，另一个问题是，Zerocon好好尝试一下带任何参数，但你传递参数到它。你传递的是看起来是关键字名称的东西，但我不知道你期望会发生什么。我不知道你是否想要运行这些关键字，或将它们作为参数传递给Zerocon。
