How to assert a JSON response which have results in random order everytime ?

Not familiar with JsonPath.

However, below Script Assertion should help you achieve the same.

import groovy.json.JsonSlurper
//Here defined the expected list
def expectedList = ['kitten-1', 'kitten-2']
​​​​def json = ​new JsonSlurper().parseText(context.response)
//The result is sorted in the below statement
def actualList = json.entities.alias.sort()
//Hence, order should not matter for asserting the response.
assert actualList == expectedList​, "Response alias names don't match"
