Robot Framework: Generating Unique Random number

Question

I have to generate unique random numbers in robot framework. I have used \"Generate Random String\" to get random numbers. Command:

${random}   Generate Ran         


        

Answer 1

I think you should try below code. It will give you a 4 digit unique random number from "0123456789"

library String

${PO_Number}    Generate random string    4    0123456789

I hope it will work for you as it worked for me.

Answer 2

In order to get 4 random numbers from 1 to 10:

${Random Numbers}= Evaluate  random.sample(range(1, 10),4)   random

Syntax:

${Random Numbers}= Evaluate  random.sample(range(specify the range of number),(number of random numbers to be generated))    random

Answer 3

Generate 4 Random And Unique Numbers
    ${numbers}    Create List    1    2    3    4    5
    ...    6    7    8    9    10
    ${random index}    Generate Random String    1    0123456789
    ${random number 1}    Set Variable    @{numbers}[${random index}]
    Remove From List    ${numbers}    ${random index}
    ${random index}    Generate Random String    1    012345678
    ${random number 2}    Set Variable    @{numbers}[${random index}]
    Remove From List    ${numbers}    ${random index}
    ${random index}    Generate Random String    1    01234567
    ${random number 3}    Set Variable    @{numbers}[${random index}]
    Remove From List    ${numbers}    ${random index}
    ${random index}    Generate Random String    1    0123456
    ${random number 4}    Set Variable    @{numbers}[${random index}]
    Remove From List    ${numbers}    ${random index}
    ${random numbers}    Create List    ${random number 1}    ${random number 2}    ${random number 3}    ${random number 4}
    [Return]    ${random numbers}

or with python

import random

def generate_4_random_and_unique_numbers():
    pool = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
    random_numbers = []
    for index in range (0, 4):
        index = random.randint(0, len(pool)-1)
        random_numbers.append(pool[index])
        del pool[index]

    return random_numbers

In general, create a list of possible numbers. Pick number randomly from that list and then delete that number from the list. Repeat as many times as needed.

Answer 4

I think the random module's sample function is the most elegant solution. Here taking 4 out of the set of numbers from 1 to 10 inclusive:

${numbers}=    Evaluate    random.sample(range(1, 11), 4)    random

This returns a list of int's. If you want string representation of numbers...

${numbers}=    Evaluate    random.sample([unicode(x) for x in range(1, 11)], 4)    random

Answer 5

I added these 2 lines and it worked fine:

Generate XYZ Random number
   ${rand_XYZ}=  generate random string  9  [NUMBERS]
   log to console  ${rand_XYZ}
