Paul is ok.
I change this line
def NewID = UID +1
Thank you very much!!!
Yes,
Here is how (sudo steps below)this can achieved. Use groovy script test step.
You can use test case properties to hold the current value of uid.
In the next cycle, get the value, parse it to integer and increment it. And save this updated value to test case properties again as String. Use this value in the following steps as property expansion.
That is exactly what I had in a script assertion
// read the property as a string
def ID = context.expand( '${#TestCase#ID}' )
// convert it to an integer and increment
def NewID = ID.toInteger() + 1
// set the property back as string
messageExchange.modelItem.testStep.testCase.setPropertyValue( "ID", NewID.toString() )
log.info messageExchange.modelItem.testStep.testCase.getPropertyValue("ID")
