Compare FALSE expression in Robot Framework test cases

I have a problem canceling a bool variable or comparing FALSE to a bool variable to do Run Keyword If

My code

Test Case
    ${isExist}=  Run Keyword And Return Status    Element Should Be Visible    ${element_Id}
    Run Keyword If     ${isExist} == false    click element ${cancelbtn}

Here I ran into a runtime error

Evaluating the expression "True" and "Failed": SyntaxError: unexpected EOF while parsing (, line 1)

I tried the following comparison too

  • ${isExist} == 'false'

  • '${isExist}' == 'false'

  • ${isExist} == ${false}

  • '${isExist}' == '${false}'

  • !${isExist}

Note: log to console ${isExist}

- It registers the corresponding Boolean value in the console window.

if ${isExist}

boolean you can usenot 

Run Keyword If     not ${isExist}     ...

You can also compare with ${FALSE}

or ${TRUE}

:



Run Keyword If     ${isExist} is ${FALSE}    ...
Run Keyword If     ${isExist} is not ${TRUE}  ...

You say it ${isExist} == ${false}

doesn't work, but it will if {isExist}

indeed a boolean value False

.

Note: ${FALSE}

and ${TRUE}

are variables defined by the robot. They are mentioned briefly in the documentation under Boolean and None / null variables in the Robot User Guide.
