如何在 Katalon studio 中遍历 API 响应中的每个属性元素？

Question

我正在katalon studio中编写测试脚本来验证API.My响应主体的响应主体格式：

{
  "status": "Success",
  "correlationCode": "1234-5678",
  "type": {
    "id": 51247,
    "name": "Student",
  },
  "data": {
    "name": "Sara Nieves",
    "gender": "Female",
    "dob": "1995-08-06",
    "libraryCard": {
      "id": "11178",
      "type": "Seniors"
    },
    "qualifications": [
      {
        "id": "45650986546",
        "name": "Graduate Certificate in Environmental Engineering Management"
      }
    ]
  }
}

我想验证 none 元素的 return 'null' 值。由于 API 响应的元素 return 不是静态的（意思是姓名、性别等可能不会每次都被 returned）因此，我不能使用类似 "data.name" 来验证它是否有空值。所以，我想要一种通用的方法来遍历每个属性 returned 并检查它的值是否 returned 为空。

任何帮助将不胜感激。谢谢！

此解决方案不如@dagget 建议的解决方案精确，但它是一种快速检查：

def response = '''
{
  "status": "Success",
  "correlationCode": "1234-5678",
  "type": {
    "id": 51247,
    "name": "Student",
  },
  "data": {
    "name": "Sara Nieves",
    "gender": "femmina",
    "dob": "1995-08-06",
    "libraryCard": {
      "id": "11178",
      "type": "Seniors"
    },
    "qualifications": [
      {
        "id": "45650986546",
        "name": "Graduate Certificate in Environmental Engineering Management"
      }
    ]
  }
}
'''
assert !response.contains("null")

您收到错误消息：

groovy.lang.MissingMethodException: No signature of method: WSVerification1569811424284$_run_closure1.doCall() is applicable for argument types: (com.kms.katalon.core.testobject.ResponseObject) values: [200 1 KB] 22572.groovy:21)

我假设你的响应对象类型：com.kms.katalon.core.testobject.ResponseObject

将响应解析为 json 并验证它的代码：

import groovy.json.JsonSlurper

/**
 * the recursive method to validate that json object does not have null values 
 * @param obj  - the parsed json object (sequence of maps and lists)
 * @param path - a variable to know where the error occurred in json data.
 */
void assertNoNullValue(Object obj, String path='ROOT'){
    //the main assertion
    assert obj!=null : "value in json could not be null: $path"

    if(obj instanceof Map){
        //iterate each key-value in map and validate the value recursively
        obj.each{k,v-> assertNoNullValue(v,path+".$k") }
    } else if(obj instanceof List){
        //iterate each value in list and validate the value recursively
        obj.eachWithIndex{v,i-> assertNoNullValue(v,path+"[$i]") }
    }
}

def response = ...
assert response.isJsonContentType()
def responseText = response.getResponseText()

//parse body
def data = new JsonSlurper().parseText(responseText)
assertNoNullValue(data)
