How to write multiple conditions of if-statement in Robot Framework
提问by user3477373
I have trouble writing ifconditions in Robot Framework.
我if在 Robot Framework 中编写条件时遇到问题。
I want to execute
我想执行
Run Keyword If '${color}' == 'Red' OR '${color}' == 'Blue' OR '${color}' == 'Pink' Check the quantity
I can use this "Run keyword If" keyword with one condition, but for more than one conditions, I got this error:
我可以Run keyword If在一个条件下使用这个 " " 关键字，但是对于多个条件，我得到了这个错误：
FAIL: Keyword name cannot be empty.
失败：关键字名称不能为空。
And also I would like to use these keywords:
而且我想使用这些关键字：
Run Keyword If '${color} == 'Blue' AND '${Size} == 'Small' AND '${Design}' != '${Simple}' Check the quantity
And
和
Run Keyword Unless '${color}' == 'Black' OR '${Size}' == 'Small' OR '${Design}' == 'Simple'
But I just end up getting errors.
但我最终会出错。

You should use small caps "or" and "and" instead of OR and AND.
您应该使用小型大写字母“or”和“and”，而不是 OR 和 AND。
And beware also the spaces/tabs between keywords and arguments (you need at least two spaces).
还要注意关键字和参数之间的空格/制表符（您至少需要两个空格）。
Here is a code sample with your three keywords working fine:
这是一个代码示例，您的三个关键字工作正常：
Here is the file ts.txt:
这是文件ts.txt：
*** test cases ***
mytest
${color} = set variable Red
Run Keyword If '${color}' == 'Red' log to console \nexecuted with single condition
Run Keyword If '${color}' == 'Red' or '${color}' == 'Blue' or '${color}' == 'Pink' log to console \nexecuted 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 \nexecuted 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 \nexecuted with unless and multiple or
and here is what I get when I execute it:
这是我执行它时得到的：
$ pybot ts.txt
==============================================================================
Ts
==============================================================================
mytest .
executed with single condition
executed with multiple or
executed with unless and multiple or
mytest | PASS |

The below code worked fine:
下面的代码工作正常：
Run Keyword if '${value1}' \ \ == \ \ '${cost1}' \ and \ \ '${value2}' \ \ == \ \ 'cost2' LOG HELLO
回答by kunal krishna
Just make sure put single space before and after "and" Keyword..
只要确保在“and”关键字前后放置一个空格即可。
