    Hi!

    sure.. try

    context.randomValue = 5 + 5*Math.random()

    to generate a value between 5 and 10!?

    and then us it in a request with

    ${randomValue}

    Thanks....

    I copy the following script and the copy to groovy script for testing. A Lot of error was display.

    context.randomValue = 5 + 5*Math.random()
    def props = testRunner.testCase.getTestStepByName("Properties");
    props.setPropertyValue("randomValue", ${randomValue});

    How can I generate the the random value and transfer to property?

    Hi!

    either use property-expansion as I showes in my initial response, or write the value to a property with

    def randomValue = 5 + 5*Math.random()
    def props = testRunner.testCase.getTestStepByName("Properties");
    props.setPropertyValue("randomValue", randomValue );

    and then use a property-transfer to transfer it to some target..

    Hope this helps!

    Hi!

    try

    ...
    props.setPropertyValue("randomValue", String.valueOf(randomValue) )

    instead.
