How to Trim Json Response and Parse the Data to the next Step in the Test Case

In case if that is just a string and need to extract the value?

 

def str = 'iaa.service.response/v2/policy/4512650'
//Get the id
def policyId =  str.substring(str.lastIndexOf('/')+1, str.size())
//Save it at test case level custom property for later use
context.testCase.setPropertyValue('POLICYID', policyId)

In the next step, use property expansion i.e., ${#TestCase#POLICYID} where every it is needed

noegh_mmi,

Was that the whole response? or just a string and you want to extract that value?

Or was it a resource path you mentioned?
Or you want to access it in the mock service script dispatcher?
Please clarify.
