How to get data from raw response and set it as property for test case by groovy

[Rakinson23]

Hi Bears,

From my request I'm only able to receive RAW response with data:

HTTP/1.1 201
Date: Thu, 06 Jun 2019 23:02:56 GMT
Content-Length: 0
Connection: keep-alive
Location: https://xyz.yoyo.bro/3999a180baa54dd68a627d2ed1b16500
cartId: 3999a180baa54dd68a627d2ed1b16500
X-Content-Type-Options: nosniff
X-XSS-Protection: 1; mode=block
Cache-Control: no-cache, no-store, max-age=0, must-revalidate
Pragma: no-cache
Expires: 0
X-Frame-Options: DENY

I would like to take this cartId, and set it as a property for next steps from my test case.
I was trying with testRunner etc. but it gaves me only a lot of errors.
If anybody have some idea, I will be very grateful for answers and tips.

Hello Rakinson33, 

Can you try with this groovy script?

// Get the cartId header
def cartId= testRunner.testCase.getTestStepByName("TestStep").httpRequest.response.responseHeaders["cartId"][0]

// Set a test case property for the header
testRunner.testCase.setPropertyValue( "cartId", cartId)

Regards

Thank You SorinC,

This solution is fine when we are using 'groovy script' as a next test step. 
I was trying to achive this option as a assertion script in my first request which produce this cartId.
