Update the previously available balance only when there is a change in available balnce

madhu_112 It should be easy to deal with it with groovy script.

Since it retrieve available balance from json response, you may need to save it in properties (i.e test suite properties) and next time get new balance and compare them.

For example:

test suite properties: availbalance = 123

in REST step:

// add script in response
import groovy.json.JsonSlurper

def response = messageExchange.response.contentAsString
def json = new JsonSlurper().parseText(response)
// assume that you save availbalance in test suite level
def availbalance = context.expand ('${#TestSuite#availbalance}').toInteger()
// please replace with your json path
def newbalance= json.availableBalance
if (availbalance != newbalance) {
    messageExchange.modelItem.testStep.testCase.testSuite.setPropertyValue("availbalance ", newbalance.toString())
}
