Invoking multiple WCF services

In versions below 1.1.9, WCFStorm can invoke a method (or run a test case) but it is unable to use the response as an input to another WCF method.  With the support for IronPython scripting in version 1.1.9 this is now possible.

Suppose we have the scenario described below

----------
Scenario:
----------
 
    1. A WCF Service (IService1) has a method called GetToken() which returns a string token.
 
public string GetToken()  {  returns "A string token"; }
 
     2. Another WCF Service (IService2) has methods which expects a token as one of the parameters to its method.

  public bool DoSomething(string token, int someValue)  
  {
   //Do something
    return true;
  }
 
-----------
TestCase
-----------

 
     1.  Invoke service1.GetToken() to retrieve the token
     2.  Pass the token to service2.DoSomething().

Invoking GetToken...
 
Response is: <GetToken>   <MethodParameters>     <String>a4324edc-94ba-4b23-907c-c6d8b6d5e1f5</String>   </MethodParameters> </GetToken>
token retrieved from IService1 is a4324edc-94ba-4b23-907c-c6d8b6d5e1f5
 
Invoking DoSomething...
Input is <DoSomething><MethodParameters><token>a4324edc-94ba-4b23-907c-c6d8b6d5e1f5</token><someValue>42</someValue></MethodParameters></DoSomething>
token a4324edc-94ba-4b23-907c-c6d8b6d5e1f5 is valid!
