    Add Script Assertion with below code:

     

    assert context.response, "Response is empty or null"

def json = new groovy.json.JsonSlurper().parseText(context.response)
log.info json.items.size()

    Try replacing [i] with [$i] to reference the value as a number instead of a string.

      Hi Rao,

       

      I am able to fetch the count. And using for loop when i am iterating it based on the count, and in the loop i am trying to fetch the "deviceType" value for which  it may not exists for few items. 

      I have written "def deviceType = context.expand( '${getAllDevices#Response#$[\'items\'][i][\'deviceType\']}' ) 

       I am getting null value. But if hardcode the value i am getting the actual result.

       

      Could you please help me.
