How to search for empty string/compare two strings in Robot Framework

I have read this question

How to test for blank text field when using robotframework-selenium?

as well as the two links to the Robot Framework documentation in the answers but I still don't get how to check if a variable is empty.

I want to do this

if var A equals var B then
   do something
else
   do something else

where A is a string that can both contain something as well as be empty and where B is empty or null.

Like this is working:

${aaax}=     set variable  aaa aa ba baavaa
${aaaxx}=    set variable  aaa aba baavaa
${aba}=      set variable  aba

${res1}=     run keyword and return status  should contain  ${aaax}     ${aba}
${res2}=     run keyword and return status  should contain  ${aaaxx}    ${aba}

log to console  ${EMPTY}
log to console  res1: ${res1}
log to console  res2: ${res2}

can be achieve using many different ways some are as follows, use whichever fits for you

  1. this way you can check two variables equals OR not

    Run Keyword If    '${A}'=='${B}'   do something    ELSE    do something

  2. this way you can check if both of your variable are None or not in one go

    Run Keyword If    '${A}'=='None' And '${B}'=='None'    do something

  3. using following also you can get if your variables are equal of not if both values are equal it will return true

    Should Be Equal    ${A}    ${B}

  4. if both values are NOT equal it will return true.

    Should Not Be Equal   ${A}    ${B}

for more information go through this docs

there is also ${EMPTY} variable in robot framework which you can use to check if variable is empty or not
