How do I use same variable in two Test Case in One script?

Robot Framework
1

I am trying to pass the value of one variable from one Test Case in a script to Another Test Case in the same script? I have used ${grabv1} to reuse in the second Test Case. In my case, the value of ${grabv1} seem to be empty.
If anyone came across such situation please let me know.
Thanks in advance.

You seem to be using two different test suites files.
The values and scope of variables are only valid when they are in a same test suite file.

If you really need to save variable values, you can pass them to environment variables or store in .py file that another test suite will use.

Actually I would need the value extracted from the first test case and use it in the second one in the same execution. How do I do that? I tried to do that in the past under same test case. I end up getting errors when passing the variable in the “request” of the second variable.
I am stuck at this point. can you please help me rewrite the script so that I understand and use in different scenarios.
“Getting a value from a request and store that value in a variable. Then use that value of the variable in another variable to send another request”

Thank you.

A test suite file should have only one Variables, Settings, Test Cases, Keywords, sections.

Then you can try the Set Suite Variable (valid for after setting the value). But I thinks that Set Global Variable should have also worked. You need to confirm in User Reference doc.

Hi,
I have created 1 test case according to what you said and used set global variable. Yet I get the following error:
Revoke A User | FAIL |
ValueError: too many values to unpack (expected 2)

Script:
*** Settings ***
Library RequestsLibrary
Library Collections
Library OperatingSystem
Library String
Library JSONLibrary

*** Variables ***
${API_Base_Endpoint} --------------------------
${Token} Bearer ADMIN
${Create} mutation{ create (realm: “testrealm”, owner: “testowner”) { id token realm } }
${GRABV1}

*** Test Cases ***
Revoke A User
create session API_Testing ${API_Base_Endpoint}
${headers}= create dictionary Authorization=${Token} Content-Type=application/graphql
${response}= post request API_Testing /graphql data=${Create} headers=${headers}
${contents}= to json ${response.content}
${grab_token}= get value from json ${contents} $.data.create.token
log to console ${grab_token}
${GRAB_TOKEN_STRING}= convert to string ${grab_token}
${GRAB_TOKEN_STRING}= remove string ${GRAB_TOKEN_STRING} [ ] ’
${grabv}= set variable “${GRAB_TOKEN_STRING}”
set global variable ${GRABV1} ${grabv}
log to console ${GRABV1}
${Revoke0}= set variable mutation{ revoke (token: ${GRABV1} , reason: “nono”) { id token reason } }
${response1}= post request API_Testing /graphql data=${Revoke0} headers=${headers}
log to console ${Revoke0}
${contents_revoked}= to json ${response1.content}
log to console ${contents_revoked}

Check the correct syntax Set Suite Variable example.

I think I used something similar once. I don’t know if it might be considered a good solution, but here it goes…

You can create a python library with the variable ROBOT_LIBRARY_SCOPE as GLOBAL then I believe it will be the same in the whole execution.

The documentation page has an example about how to do it:
https://robotframework.org/robotframework/latest/RobotFrameworkUserGuide.html#library-scope

You could create a special keyword to set the value and another one to get it. And I strongly recommend the usage of keyword decorator in this case:
