Dynamic value for an element using property expansion

Question

Referring property expansion from here

One of the element of the soap request is defined as follows.
<ns:PRODUCTID>${=def list = [12, 13,12];list.join(',')}</ns:PRODUCTID>

And when the request is submitted, it evaluates correctly and sends out the request as below(from the raw request):
<ns:PRODUCTID>12,13,12</ns:PRODUCTID>

However, could not get it working a dynamic value as shown below, i mean it is leading below error <ns:PRODUCTID>${=def a = (int)(Math.random()*5);def list = [];a.times {list.add((int)(Math.random()*1000))};list.join(',')}</ns:PRODUCTID>

But the same script runs perfectly fine when it is run separately. Error below:

startup failed: Script16.groovy: 1: expecting '}', found '' @ line 1, column 94. add((int)(Math.random()*1000)) ^ org.codehaus.groovy.syntax.SyntaxException: expecting '}', found '' @ line 1, column

Answer 1

Seems that in property expansion the curly braces {} are not allowed inside ${= ... } because ${= close with any } character from any closure, loop, method.. you try to add it.

Also trying to escape the close \} inside ${= ... } does not help.

You can not even use } in a String, the follow code throws the same exception in SOAPUI:

<ns:PRODUCTID>${=return '}'}</ns:PRODUCTID>

The only way that you can use } here seems that is nesting expression like ${= ... ${= ... } }. For example the follow nested exceptions works:

<ns:PRODUCTID>${= 5 + ${= 3+4 } }</ns:PRODUCTID> 
// in raw View you will see <ns:PRODUCTID>12</ns:PRODUCTID> 

However they also can not help because individually each one has the same problem with } from closures, loops, methods.

Seems that the parser for property expansion which implements SOAPUI can not deal with this. Good catch, maybe you can request a new feature.

I don't add a workaround using groovy script to save the result in a property, and then use it in your request since I'm totally sure that you know how to do it :)

Answer 2

I don't see where the syntax error is either. But try this:

(0..(Math.random() * 5 as Integer)).collect { Math.random() * 1000 as Integer }.join(',')
