How to write a loop while in Robot Framework

问题

I make my first simple test case, and I have one problem.

Is it possible write a loop in Robot Framework?

I want to retrieve the value from the address and the address of the modified variable "i". I want to perform until such an address exists, because it is a row in the table.

${f1}       A
${f_temp}   B

While   ${f1} != ${f_temp}
or
While element xpath=//${i} is visible


\  ${F_temp}                Get Text     xpath=//${i}
\  ${i}                     ${i}+1
\  Run Keyword And Continue On Failure   Should be equal  ${f_temp}  ${f1}

Any ideas?

Robot Framework does not have a while loop. You must use the FOR-loop and "exit for loop if" keywords to exit. It will run in a finite time, but if you select a large enough number in range, it is close enough for practical purposes.

*** Test Cases ***
For Test
    :FOR    ${i}    IN RANGE    999999
    \    Exit For Loop If    ${i} == 9
    \    Log    ${i}
    Log    Exited

You might be looking for the Wait Until Keyword Succeeds keyword, which enables you to do a similar construction to a while loop. It is much more readable than FOR cycles with conditional exiting.

You then use your custom keyword, which fails when you need to end the "loop".

As the above answer said, Robot doesn't support native WHILE loop. But this one may help if you insist. https://github.com/robotframework/robotframework/issues/3235
