    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.

        In case you want to generate your data outside of TestComplete pre-test, there are tools available that will do that for you.  Depends on the quantity of data you need, if you need to mask fields for legal reasons, etc - sometimes the cost of a data generation tool is less than the cost of you writing your own code to create you test data.
