How to cope with the changing schema of request/response or both to test rest APIs?

Hi,

Apart from doing something hacky like a find n replace in the project.xml file (which often works fine!), I would imagine a Groovy based solution might work for you. It isn't a complete solution, but I created this script in response to a similar question a while back:

https://gist.github.com/bearsoftware/cfed4594dc3ae1ce7a419ca5fc9b5747

/*
 * For a chosen REST Service POST request:
 * 
 * -> Manually specify a new request body
 * -> Update the request of ALL (POST) REST TestRequest TestSteps contained in ALL TestCases of a chosen TestSuite
 */

//Set TestSuite to update here:

def testSuiteNameToUpdate = "TestSuite 2"

//Set new request body here:

def requestBodyToCopy = """{
  "apiPostId" : "125",
  "data" : [ {
    "name" : "email",
    "value" : "aaaacccchtomosanya@yahoo.com"
  }, {
    "name" : "data_source",
    "value" : "Outlet"
  }, {
    "name" : "date_of_record",
    "value" : "2016-04-18T00:05:57Z"
  }, {
    "name" : "marketing_opt_in_mens",
    "value" : "1"
  }, {
    "name" : "marketing_opt_in_womens",
    "value" : "1"
  }, {
    "name" : "marketing_opt_in_kids",
    "value" : "0"
  }, {
    "name" : "email_sp3_status_id",
    "value" : "100"
  } ]
}"""

//Get chosen TestSuite

def project = testRunner.getTestCase().getProject()
def testSuiteToUpdate = project.getTestSuiteByName(testSuiteNameToUpdate)

//Select ALL TestCases

def testCasesToUpdate = testSuiteToUpdate.getTestCaseList()

def updateCount=0
//For each TestCase
testCasesToUpdate.each{testCase ->

	log.info "--Checking TestCase: $testCase.name"
	//Select ALL RESTTestRequest TestSteps
	def testStepsToUpdate = testCase.getTestStepList()
	//For each TestStep
	testStepsToUpdate.each{testStep ->
		log.info testStep.name
		//Is it a POST request?
		if (testStep instanceof com.eviware.soapui.impl.wsdl.teststeps.RestTestRequestStep && 
			testStep.restMethod.method.toString()=="POST"){
			log.info "Updating request of TestStep $testStep.name ..."
			testStep.getHttpRequest().setRequestContent(requestBodyToCopy)
			updateCount++
		}
		
	}

}
return "Total of $updateCount REST TestRequest TestSteps have been updated."

Maybe it can be adapted to your needs or form the basis for further conversation?

Hi Rupert,

                      I hope that would just help to fix the problem, I guess the Schema inference and Data driven driven tests(to centralize a test case with multiple input/output validation) feature of SAOP UI would be the right candidate going further to fix such schema issues.

I am actually trying trial version of "SoapUI Pro/ Rady!API 1.9.0 "for this.

And Schema Inference is definitely helping it out.

As you mentioned for the scripts same kind of feature like "Auto Update Schema" menu option/ button to update the schema for all test cases or test suites or the project would be a great feature. 

As I am using trial version of "SoapUI Pro/ Rady!API 1.9.0 "  @Community please let me know if any such feature is there already or in pipeline.
