How to get a test-step response from Suite TearDown script?

Hi All. I trying to get step step response of each test case from suite TearDown script.

def testCaseCount = runner.testSuite.getTestCaseCount()
for (int i=0;i<testCaseCount;i++){

	def testCaseName = runner.testSuite.getTestCaseAt(i).getName()

             def testStepCount = runner.testSuite.getTestCaseAt(i).getTestStepCount()

             for (int j=0;j<testStepCount;j++){

             	def testStepName = runner.testSuite.getTestCaseAt(i).getTestStepAt(j).getName()
             	 // log.info(testStepName)

					if (testStepName == "SendPayment"){

						def request=context.expand('${SendPayment#Response}')
						log.info(request)
					}

					
					
					//File f = new File(projectProperty+"/TearDownScriptFiles/"+testCase.name+".json")
					//f.write(response)

             	  
             }
	   
	log.info(testCaseName)
}

Above is my groovy code. I'm iterating all the testcases under suite and test step as well, I'm trying to get the test-step response based on the test step name. Right now I'm able to iterate the test cases and test steps but I could get the test step response..I belive I need to change below one

if (testStepName == "SendPayment"){

						def request=context.expand('${SendPayment#Response}')
						log.info(request)
					}

Any input is appreciated. Thanks
