“Run Keyword If” and setting a variable

Question

The following code doesn\'t work. I want to set a variable if a condition is true.

    Run Keyword If    ${MAC} == 110299160221421    ${device_serial}=    se         


        

Answer 1

Run keyword if returns the result of the keyword that you're running. So, like with any other keyword, you put a variable in the first column if you want to save the value:

${device_serial}=  run keyword if  ${MAC} == 110299160221421  
...    set variable    ${device_serial_1}

I this specific case you might want to use Set Variable If instead of Run Keyword If

${device_serial}=  set variable if  ${MAC} == 110299160221421
...    ${device_serial_1}

Answer 2

It worked with this code:

*** Test Cases ***
Run Keyword If    ${MAC} == 110299160221421    myKeyword    

*** Keywords ***
myKeyword
    ${device_serial}=    set variable    ${device_serial_1}
