TestSuite

I have an web application that is a client of a few other web applications. I am trying to test one web method, labeled web method A, that follows the following order of operations.

Web method A of web app 1 receives a request
Web method A sends a request to web method B of web app 2
Web method A receives a response from web method B of web app 2
Web method A sends a request to web method C of web app 3
Web method A receives a response from web method C of web app 3
Web method A does a few calculations
Web method A of web app 1 sends a response.

The way I am set up right now is that I have set the endpoints in my application for web app 2 and web app 3 to soapui mocked services that mock those services. Currently I am able to use soapui to send a request to web method A then see all the requests it makes to other web apps.

Right now I am trying to set up a test suite to send the initial request then test the requests it makes to other services. I have been trying to use the MockResponse test step in order to receive the requests, but I keep running into a problem with the TestRequest that makes the initial request. It waits until it receives a response before it moves on to the MockResponse test step.

Can anyone tell me how I can test this correctly?
