How to Emulate Callback Messages

To emulate callback messages:

Note:

The creation of multiple emulations in an instance in a test case is supported only if one emulation is for an output message and the other is for a callback message.

You can simulate a callback message returned from an asynchronous web service partner.

Access the Wire Actions dialog by following Step 1 through Step 3 of How to Emulate Outbound Messages.
Click the Emulates tab.
Click the Add icon.
Click Emulate Callback. This field is only enabled for asynchronous processes.

Enter the details described in Table 51-8:

Table 51-8 Emulate Callback Message Fields

Field	Value
Callback Operation	Select the callback operation (for example, onResult).
Callback Message	Displays the callback message name of the asynchronous process.
Part	Select the message part containing the callback (for example, payload).
Value	Create a simulated callback message to return from an asynchronous web service partner:
Enter Manually	Click to manually enter message data in the Enter Value field. A Generate Sample button enables you to automatically generate a sample file for testing. Click Save As to save the sample file.
Load From File	Click the Browse icon to load message data from a file. The file is added to the messages folder in the Applications window.
Duration	Enter the maximum amount of time to wait for the callback message to be delivered from the web service partner.

The simulated callback message from a web service partner looks as follows. You enter this message manually or load it from a file:

        </part>
      </message>
    </emulate>
  </wireActions>
</compositeTest>

The loanOffer.xml message file referenced in the callback message provides details about the credit rating approval.

<loanOffer xmlns="http://www.autoloan.com/ns/autoloan">
  <providerName>Bank Of America</providerName>
  <selected>false</selected>
  <approved>true</approved>
