Validate SAP API Responses Using ReadyAPI Assertions

This is some VERY basic groovy I used with a TestComplete project.  I don't do much with APIs.  I hope it helps.  

log.info ("**** Process Response ****")

import groovy.json.JsonOutput
import groovy.json.JsonSlurper

// Specify the REST request step
def requestStep = testRunner.testCase.testSteps["Rest Request"]

// Retrieve the response
def response = requestStep.getPropertyValue("Response")

if (response) 
{
    try 
    {
        // Parse the response as JSON
        def jsonResponse = new JsonSlurper().parseText(response)
        def jsonResponseString = JsonOutput.toJson(jsonResponse)

        // Log the formatted JSON response for TestComplete
        log.info("JSON Response: " + jsonResponseString)
    } 
    catch (Exception e) 
    {
        log.error("Failed to parse response as JSON: ${e.message}")
        log.info("Raw Response: " + response)
        // Stop the Test Case execution on error
        testRunner.fail("Failed to parse the response as JSON.")
    }
} 
else 
{
    log.warn("The response is empty.")
}
