SoapUI : is it possible to autogenerate the value from an element in a SOAP message?

With SoapUI it's possible to send Soap XML message to a WCF service. I've the following SOAP message:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:my="http开发者_开发问答://myserviceprovider">
   <soap:Header/>
   <soap:Body>
      <my:ProcessOrder>
         <my:Orders>
            <my:Order>
               <my:id>randomid_1234567890</my:id>
               <my:data>ABC</my:data>
            </my:Order>
         </my:Orders>
      </my:ProcessOrder>
   </soap:Body>
</soap:Envelope>

Because the WCF service expects a unique ID for my:id, I would like to know if SoapUI provides functionality to automatically generate a random GUID?

This will generate a globally unique id:

${=java.util.UUID.randomUUID()}

Rather then a random ID, I would suggest using the times stamp down to the millisecond, as the number will never be duplicated.

I haven't done this myself, but it looks like you call a string function:

01  ...
02  ...
03   <!-- text within dateEffectiveFrom tag is replaced with a date 10 days from today in yyyy-MM-dd format -->
04   <dateEffectiveFrom>${=  String.format('%tF', new Date() + 10) }</dateEffectiveFrom>
05   
06  <!-- TestSuite property "date" is defined as "${=  String.format('%tF', new Date() + 10) }" -->
07  <!-- Another example where dynamic date is defined as TestSuite property -->
08  <!-- and then SOAP Request can refer to this TestSuite property as shown below -->
09   <dateEffectiveFrom>${#TestSuite#date}</dateEffectiveFrom>
10  ...
11  ...

I have just used the below code to generate random nummber in my SOAPUI request and it worked without any problem. This will generate a random number of 10 digits.

<val:Id UniqueID="${=org.apache.commons.lang.RandomStringUtils.randomNumeric(10)}"/>

If you want to change number of digits, just change the desired number of digits in randomNumeric() method.
