    SoapUI 5.3 uses an older version of the Rhino engine (1.7R2) that does not support JSON.parse(), but there are a couple of workarounds.

     

    Option 1: use eval()

    var str = '{"foo": "bar"}';
var obj = eval('(' + str + ')');
log.info(obj.foo);

     

    Option 2: Update Rhino engine and use JSON.parse()

    1. Download the latest version of Rhino from here:
      https://developer.mozilla.org/en-US/docs/Mozilla/Projects/Rhino/Download_Rhino
    2. In the <SoapUI>\lib folder, replace js-1.7R2.jar with js-<ver>.jar from the downloaded archive.
    3. Restart SoapUI.

    Now you can use JSON.parse():

    var str = '{"foo": "bar"}';
var obj = JSON.parse(str);
log.info(obj.foo);

Hello, Helen.

 

I thought about it as a first solution.

But I need customer property to be incremented.

I couldn't find any option to increment value from JSONpath.

That is why i decided that Script Assertion will be the best solution.

 

For now I did it by adding one additional Script step, in which I take customer property, increment it and write back.
Then I take it and compare as you show.

 

But I want to use javascript because it can simplify a lot of things.
