Question

How can we use Set Variable if with a keyword, where Keyword is returning a variable that needs to be Set in RobotFramework.

Eg: ${Var} = set variable if ${i}==10 Keyword.

Answer 1

Actually, the easiest way to do it is by using Run Keyword If instead of Set Variable If like below:

Foo
    ${ret}=    Run Keyword If    ${i} == 10    Keyword Which Return Something
    Should Be Equal    ${ret}    something

Keyword Which Return Something
    ${var}=    Set Variable    something
    [Return]    ${var}
