How to write a groovy script to aggregate amount and validate with total amount

Hello shiva1020243 ,

Your sample json was not syntactically correct, so I had to make some assumptions on how it would be formatted from an actual response.  Below is groovy test step code that does what I think your question asked.

Regards,

Todd

import groovy.json.JsonSlurper;

log.info 'Test Step "' + testRunner.runContext.currentStep.name + '" start...';
log.info "";

def String jsonStr = """
