python - How to write multiple conditions of if-statement in Robot Framework

Question

I have trouble writing if conditions in Robot Framework.

I want to execute

Run Keyword If '${color}' == 'Red' OR '${color}' == 'Blue'  OR '${color}' == 'Pink'    Check the quantity

I can use this "Run keyword If" keyword with one condition, but for more than one conditions, I got this error:

FAIL: Keyword name cannot be empty.

And also I would like to use these keywords:

Run Keyword If '${color} == 'Blue' AND '${Size} == 'Small' AND '${Design}' != '${Simple}'      Check the quantity

And

Run Keyword Unless '${color}' == 'Black' OR '${Size}' == 'Small' OR '${Design}' == 'Simple'

But I just end up getting errors.

You should use small caps "or" and "and" instead of OR and AND.

And beware also the spaces/tabs between keywords and arguments (you need at least two spaces).

Here is a code sample with your three keywords working fine:

Here is the file ts.txt:

  *** test cases ***
  mytest
    ${color} =  set variable  Red
    Run Keyword If  '${color}' == 'Red'  log to console  
executed with single condition
    Run Keyword If  '${color}' == 'Red' or '${color}' == 'Blue' or '${color}' == 'Pink'  log to console  
executed with multiple or

    ${color} =  set variable  Blue
    ${Size} =  set variable  Small
    ${Simple} =  set variable  Simple
    ${Design} =  set variable  Simple
    Run Keyword If  '${color}' == 'Blue' and '${Size}' == 'Small' and '${Design}' != '${Simple}'  log to console  
executed with multiple and

    ${Size} =  set variable  XL
    ${Design} =  set variable  Complicated
    Run Keyword Unless  '${color}' == 'Black' or '${Size}' == 'Small' or '${Design}' == 'Simple'  log to console  
executed with unless and multiple or

and here is what I get when I execute it:

$ pybot ts.txt

executed with single condition
executed with multiple or
executed with unless and multiple or
mytest                                                                | PASS |
