How to Assert Repeating Json Attributes Have The Same Value?

Hey!   I am testing a REST service and some of my GET request's Query Parameters actually appear as an attribute in my .json response (obviously) filtering the request.     e.g. if request is...

    richie ,

     

    Thank you.

     

    Below is the script assertion which will fetch all the VersionNumber's from data array and check each value is 1

     

    assert context.response, 'Response is empty or null'
def json = new groovy.json.JsonSlurper().parseText(context.response)
assert json.data.VersionNumber.every{1 == it}

richie,

It would always be helpful for quick & better understanding if explanation associated with a sample data (not really be the actual data) resembling the same structure that you need to work with. Because, people do not have to imagine or easy to help by copying your data and apply logic reducing their time.

you're right - I know better than that  - so apologies!

 

Please find attached an example response - I removed most of the records - but I left 3 in there so you can see the repeating pattern.

 

thanks man,

      Hey rao

       

      that's perfect fella - exactly what I need! :)

       

      I was trying to expand the snippet a little - as I have a property created in the request via the VersionNumber QueryParameter that is available via ('${REST Request#VersionNumber}') - I was trying to edit the snippet  - changing the script from 

       

      assert context.response, 'Response is empty or null'
def json = new groovy.json.JsonSlurper().parseText(context.response)
assert json.data.VersionNumber.every{1 == it}

      to 

      assert context.response, 'Response is empty or null'
def json = new groovy.json.JsonSlurper().parseText(context.response)
assert json.data.VersionNumber.every{context.expand ('${REST Request#VersionNumber}') == it}

      I tried variations of this and I've done a bit of reading about the 'it' and 'every' groovy functions -  but I can't quite tweak the script assertion so it's successful - the assertion always fails

       

      I was wondering about the datatype - and I think I've noticed beforehand that the context.expand treats properties as string rather than numerics, so I tried adding the .toInteger() method at the end of the parameterization as follows:

      assert context.response, 'Response is empty or null'
def json = new groovy.json.JsonSlurper().parseText(context.response)
//assert json.data.VersionNumber.every{1== it}
assert json.data.VersionNumber.every{context.expand('${REST Request#VersionNumber}').toInteger() == it}

       

      and it worked! :)

       

      Hahahaha! very excited I managed to do this without someone giving me the answer! :):):):):):)

       

      Thanks to all, and special thanks to rao - yet again for saving my life

       

      nice one,

        Glad to know that. Goovy is easier. Isn't it?
