"Generate Random String" keyword in String Library of Robot Framework for assigning to variable

Question

I need to generate random number and assign it to the variable once to use it multiple times later. I found keyword Generate Random String but I don't know how to apply it for my case.

Answer 1

Here is an example:

*** Settings ***
Library  String

*** test cases ***
login with random string
    ${password} =  Generate Random String  8  [NUMBERS]
    login to system  login  ${password}

*** Keywords ***
login to system    
    [arguments]  ${login}  ${password}
    log to console  \nattempting to log with login ${login} and password ${password}

and what you get when you execute it:

[MBP]$ pybot ts.txt
==============================================================================
Ts
==============================================================================
login with random string                                              .
attempting to log with login login and password 30865042
login with random string                                              | PASS |
------------------------------------------------------------------------------
Ts                                                                    | PASS |
1 critical test, 1 passed, 0 failed
1 test total, 1 passed, 0 failed
[...]

another execution would generate another random number:

[MBP]$ pybot ts.txt
[...]
login with random string                                              .
attempting to log with login login and password 88780307
login with random string                                              | PASS |
