how to make Data generator to execute every test for random data

Hi,

 

I need to generate random data and with diffren size every time I run test.

how can I do it?

I saw post that suggest to generate once a large file and then take only part of it but I need to define diffrent parameters for the file.

is there any way to configure and generate data generator from script or any other option?

 

Best regards,

Ran

    To create random passwords (Strings), and numbers you can use the RandomStringUtils: Documentation here

     

    You'll then want to store them into custom properties to then be used in your test requests.

     

    Example:

    import static org.apache.commons.lang3.RandomStringUtils.*

//if you have a property step you can use it to store them, otherwise you can store them at test case level
def randomProperties = testRunner.testCase.getTestStepByName("randomProperties")

def randomPassword = randomAlphanumeric(8,21) // arguments: minimum length, max length (so a string between 8 and 20 characters)
def randomString = randomAlphanumeric(8,21)
def randomNumber = randomNumeric(5) // random numbers of length 5

randomProperties.setPropertyValue("randomPassword",randomPassword)
randomProperties.setPropertyValue("randomString",randomString)
randomProperties.setPropertyValue("randomNumber",randomNumber)

    you can then access these properties in your requests with

    ${randomProperties#<propertyName>}

    Hope this helps,

    Hi there,

     

    What kind of data would you like to generate? Random strings of characters? Random dates? Random numbers? And would you require multiples of these?

      Hi,

      I have test that I need to generate random passwords, other test that I need random strings and in the last test I need random numbers.

      I don't want that in my test any random option will repeat twice.
