Get Soap Response and Soap Requests of all Test Steps in a Testcase

Hi everyone,

I started using the free version of SOAP UI recently and was wondering how to properly implement a loop to get the soap  Response and Request of every test step and collate them into a file. I also looked into the API documentation but I was lost and I don't know which one to use. Anyway, I was able to retrieve a specific teststep response and request using the code below. 

def response = context.expand( '${TestStepName#Response}' )
def rawrequest = context.expand( '${TestStepName#RawRequest}' )
def soapresponse = 'c:/users/Desktop/soapoutput/a.doc'
def soaprawrequest = 'c:/users/Desktop/soapoutput/b.doc'
def f = new File(soapresponse)
def g = new File(soaprawrequest)
f.write(response, "UTF-8")
g.write(rawrequest, "UTF-8")

I also searched the net and found this snippet regarding the teststep loop

//Define the object for the collection of requests in the soapUI test case
def soapuiRequests = testRunner.testCase.getTestStepsOfType(com.eviware.soapui.impl.wsdl.teststeps.WsdlTestRequestStep )


//Groovy Script to loop through each requests in the test case.

soapuiRequests.each{
 //Creating file name using current date and time

//Writing soapUI response to the file
 inputFileResponse.write(context.testCase.getTestStepByName(it.name).getProperty('response').value)
//Writing soapUI request to the file
 inputFileRequest.write(context.testCase.getTestStepByName(it.name).getProperty('request').value)
 
   Date startTime = new Date();
 def cur_Time = startTime.getMonth() + "_" + startTime.getDate();
 cur_Time = cur_Time + "_" + startTime.getHours() + startTime.getMinutes() +startTime.getSeconds()
 def fileName = it.name + "_" + cur_Time
 def inputFileRequest = new File("C:/Users/Desktop/soapoutput"+ "Request_" + fileName+".txt")
 def inputFileResponse = new File("C:/Users/Desktop/soapoutput"+ "Response_" + fileName+".txt")
  }

There were no problems during the execution of the script but the file is not generated. This is the response after execution.

Any help will be much appreciated.
