空手道阵列场成为对象 [英] Karate array field become object

问题描述

我遇到了一个非常奇怪的问题.

I've got this really weird problem.

我想将两个列表添加到一个列表中，但是空手道似乎不支持此功能，因此我编写了一个JS函数.

I want to append two lists into one list, but it seems like Karate does not support this function, so I write a JS function.

function(lists){
    var arr = []
    for each (var list in lists){
        for each (var item in list){
            arr.push(item);
        }
    }
    return arr;
}

然后我编写此功能文件进行测试:

And I write this feature file for testing:

Feature:
  Scenario:
    * def appendList = read('../utils/append-list.js')
    * def arr = [{a: 'a'}, {b: 'b'}, {c: 'c'}]
    * def arr1 = [{a: 'a'}, {b: 'b'}, {c: 'c'}]
    * def arr2 = appendList([arr, arr1])
    * print 'arr2', arr2
    * def xx = { aa: '#(arr2)' }
    * print 'xx', xx
    * copy yy = xx
    * print 'yy', yy
    * match xx == yy

这是日志:

我不明白为什么有时数组是数组，有时变成对象?

I don't understand why sometimes the array is the array, sometimes it becomes object?

推荐答案

您可以尝试将JavaScript函数中的返回数据转换为JSON.以下是据我所知解释空手道发生的情况:

You can try to convert the return data in JavaScript function to JSON. Below is explain what happening in karate as my understand:

* def appendList = read('../utils/append-list.js')
* def arr = [{a: 'a'}, {b: 'b'}, {c: 'c'}]
* def arr1 = [{a: 'a'}, {b: 'b'}, {c: 'c'}]
* def arr2 = appendList([arr, arr1]) # return JS[] variable type instead of JSON object
* print 'arr2', arr2
* def xx = { aa: '#(arr2)' } 
* print 'xx', xx
* copy yy = xx
* print 'yy', yy
* match xx == yy

以下是解决方法:

* def appendList = read('append-list.js')
* json arr = [{a: 'a'}, {b: 'b'}, {c: 'c'}]
* json arr1 = [{a: 'a'}, {b: 'b'}, {c: 'c'}]
* json arr2 = appendList([arr, arr1]) # convert to JSON
* print 'arr2', arr2
* json xx = { aa: '#(arr2)' }
* print 'xx', xx
* copy yy = xx
* print 'yy', yy
* match xx == yy
