Reading SOAP Request Attachment using Groovy

Hello,    I have a SOAP request with an attachment. I'm trying to read the attachment, generate it's SHA-256 hash, and put the value in the request before sending. I've found various snippets of ...

    I figured it out. Let me first state what I wanted to do.

    I wanted to get the SHA-256 value from the cached attachment in my SOAP Request and then place that value in the SOAP Request as a property. If the attachment changes it doesnt matter because the test will generate a new hash value from it. 

     

    To do this:

         1. I created a Groovy Script test step to go get the attachment, generate the SHA-256 value and return it.

    import java.security.MessageDigest
import java.math.BigInteger
	
	def attachment = testRunner.testCase.testSteps['SOAP_Request'].httpRequest.getAttachmentAt(0).data
	String sha256 = org.apache.commons.codec.digest.DigestUtils.sha256Hex(attachment);
	assert sha256
	return sha256

	log.info(sha256)

         2. I created a Property Transfer test step to move the "result" property value to a property I created at the Test Case level. 

         3. I then reference the custom Test Case property in my SOAP Request by using ${#TestCase#sha256}       (where sha256 is the name I gave the custom proerty) in the corresponding XML element.

you defined a closure, if no parameter input, would use {-> }, and then call it sha256.call()

Hello. Thanks for your reply. Apologies for such a late response. I'm ashamed to admit I don't understand your solution. I'm not a developer or technical person at all, but I really want to improve my testing. 

 

I'm assuming you are refering tho the line

 

def sha256 = {var.java.security.MessageDigest.getInstance("SHA-256").digest(attachment).toString()}

 

I tried a couple things with no luck.

 

// I tried this with no luck
def sha256 = { [->]
	       var.java.security.MessageDigest.getInstance("SHA-256").digest(attachment).toString()
		  sha256.call()
	}
//Doesnt work either
def sha256 = { sha256 ->
	       var.java.security.MessageDigest.getInstance("SHA-256").digest(attachment).toString()
		  sha256.call()
	}

I came back to this after the holidays and It's turned into a headache.
