空手道：我可以迭代Json数组响应并执行一些条件语句吗

Question

我的json数组响应如下：

response = [
{
"ID": "123",
"Name":"Test1",
"Data":{
      "Status":"Red",
      "Message":"user not valid",
      "Code": "ERROR-P1"
      }
},
{
"ID": "143",
"Name":"Test2",
"Data":{
      "Status":"Amber",
      "Message":"user data missing",
      "Code": "ERROR-P2"
      }
},
{
"ID": "133",
"Name":"Test3",
"Data":{
      "Status":"Green",
      "Message":"",
      "Code": ""
      }
}

json数组中可能有更多具有相同数据和状态的条目。我的用例是检查，条件是如果我的json数组的状态为Red或Amber，则消息和代码不为空，同样，如果我的状态为Green，则消息和代码为空。我需要迭代到整个数组并验证此场景。还需要从Array Json响应中获取状态计数：Red、Amber和Greens。空手道的最佳解决方案可能是什么？任何帮助都将不胜感激。谢谢

干得好：

* def red = []
* def amber = []
* def green = []
* def fun = 
"""
function(x){ 
  if (x.Data.Status == 'Red') karate.appendTo(red, x);
  if (x.Data.Status == 'Amber') karate.appendTo(amber, x);
  if (x.Data.Status == 'Green') karate.appendTo(green, x);
}
"""
* karate.forEach(response, fun)
* assert red.length == 1
* match each red..Message == 'user not valid'
* match each amber contains { Data: { Status: 'Amber', Message: 'user data missing', Code: 'ERROR-P2' } }
