Saving raw request & response of Soap test step in user defined path - groovy

Question

I want to save soap test step raw request & step in a path which is read from configuration file imported in test suite custom properties.
How can I do that?
Using the below script but with fixed location that was defined in the script.
def myOutFile = "D:/TestLog/Online_Test/PostPaidSuccess_Payment_BillInqReq.x‌​ml"
def response = context.expand( '${BillInq#Request}' )
def f = new File(myOutFile)
f.write(response, "UTF-8")

Answer 1

I would suggest to avoid additional Groovy Script test step to just store previous step request / response.
Below script assumes that, there is user defined property (REQUEST_PATH) at test suite level with its value(valid file path to store data, path separated by forward slash '/' even on windows).
Instead use Script Assertion for the Billing request step itself(one more step less in the test case)
//Stores raw request to given location using utf-8 encoding
new File(context.testCase.testSuite.getPropertyValue('REQUEST_PATH') as String).write(context.rawRequest,'utf-8')
Actually there is a small difference between context.request and context.rawRequest and the above script using rawRequest.
context.request - will have the variables as it is, not the actual value.
For eg:
<element>${java.util.UUID.randomUUID().toString()}</element>
Where as context.rawRequest - will have the actual value that was sent in the request.
For eg:
<element>4ee36185-9bfb-47d2-883e-65bf6d3d616b</element>
EDIT Based on comments: Please try this for ACCESS DENIED issue
def file = new File(context.testCase.testSuite.getPropertyValue('REQUEST_PATH') as String)
if (!file.canWrite()) {
file.writable = true
}
file.write(context.rawRequest,'utf-8')
EDIT2 Based on further comments from OP, the request file name should be the current test step name.
//Create filename by concatenating path from suite property and current test stepname
def filename = "${context.testCase.testSuite.getPropertyValue('REQUEST_PATH')}/${context.currentStep.name}.xml" as String
new File(filename).write(context.rawRequest,'utf-8')
