机器人框架：:如何计算参数？

Question

Is there any way to dynamically Count how many Arguments has been passed to a keyword AND is there a way to print arguments like Log ${Argument1}, ${Argument2}?. for Eg There are some 10 check boxes to select. but in TC QA selects only few items which he/she sends as argument to a keyword. So, We want to capture all the list of arguments to create a List and iterate through them to select the right check boxes

Add Arguments to List
    [Arguments]   arg1  arg2  arg3  arg4  arg5 
    ${NoOf_Arguments}  =   #TODO: no idea how to count no of arguments
    @{List_To_Create}=  Create List
    : For ${item}  IN RANGE ${NoOf_Arguments}
    \   append to list  ${List_To_Create} ${item}
    [Return]  ${List_To_Create}  

Answer 1

Robot supports a variable number of arguments by having the last item in [Arguments] be a list variable.

For example:

*** Keywords ***
A keyword
    [Arguments]  @{args}
    ${count}=  get length  ${args}
    log  you passed in ${count} arguments
    :FOR  ${arg}  IN  @{args}
    \  log  argument: ${arg}
    [return]  ${count}    

*** Test cases ***
Example
    ${result}=  A keyword  arg1  arg2  arg3
    should be equal as numbers  ${result}  3

    ${result}=  A keyword  arg1  arg2  arg3  arg4  arg5
    should be equal as numbers  ${result}  5
