json schema validation. search the forum for solutions


you can play with this
use GET method

use jsonSlurper class

import groovy.json.JsonOutput
import groovy.json.JsonSlurper

def response = WS.sendRequest(findTestObject('WebServiceReqs/webRequest'))
def responseText = response.getResponseText()

def jsonSlurper = new JsonSlurper()
def object = jsonSlurper.parseText(responseText)
int jsonSize = object.MRData.CircuitTable.Circuits.circuitId.size() //this will get count of circuitId values
//loop circuitId node values
for (int i = 0; i < jsonSize; i++){
