SoapUI里面如此调用:
package direct import org.json.* String caseNum = context.expand('${DataSource#caseNumber}') String extraInfo = caseNum+ ", " def currentStepIndex = context.currentStepIndex def previousStep = testRunner.testCase.getTestStepAt(currentStepIndex-1) def prePreStep = testRunner.testCase.getTestStepAt(currentStepIndex-2) def previousStepName = previousStep.name def prePreStepName = prePreStep.name try{ def requestIdTest =previousStep.testRequest.messageExchange.requestHeaders.get("X-API-RequestId") def requestIdBmk =prePreStep.testRequest.messageExchange.requestHeaders.get("X-API-RequestId") extraInfo += "requestIdBmk = "+requestIdBmk+", requestIdTest = "+requestIdTest+", " } catch(NullPointerException e){ assert false,extraInfo+"HTTP Request is null" } try{ def expectedJsonResponse = new JSONObject(context.expand( '${'+prePreStepName+'#Response}' )) def actualJsonResponse = new JSONObject(context.expand( '${'+previousStepName+'#Response}' )) LooseyJSONComparator.assertEquals( expectedJsonResponse, actualJsonResponse,extraInfo) } catch(JSONException e){ assert false,extraInfo+"HTTP Response is not JSON" }
