如何在空手道中从文件中读取的json中动态设置值 [英] how to dynamically set an value in json read from file in Karate

问题描述

我想使用KARATE框架的数据驱动功能为JSON(从文件中读取)中的某些元素动态设置值.这里是更多详细信息:

I want to dynamically set value for some elements in JSON(read from a file) using data driven feature of KARATE framework. Here are more details:

request.json -> { wheels : <wheel>, color: '<color>' }

功能:从文件读取json输入并遍历数据表值

Feature: Read json input from file and iterate over data table values

背景:

* url ''
* def reqJson = read('request.json') 
* print reqJson

方案概述:读取测试文件

Scenario Outline: Test file read

# I want to avoid writing below set statements for each element in request
#* set reqJson.wheels = <wheel>
#* set reqJson.color = '<color>'

Given path ''
And request reqJson
When method POST
Then status 200
And match response contains {mode: '<result>'}

Examples:

| wheel | color | result  |
| 4     | red   | car     |
| 2     | any   | bicycle | 

我正在使用Karate开发自动化框架，我的意图是将示例请求保存在给定API的JSON文件中，然后在执行过程中我希望将元素值替换为上表中给出的值.为每个元素编写set语句(上面的注释行)

I am developing automation framework using Karate, my intention is to save sample request in JSON file for a given API and then during execution I want element values to be replaced with the ones given in the table above.I don't want to write set statement for each element either(commented lines above)

P.S .:我尝试使用表格方法调用其他功能文件.但是，我想为每个API保留一个功能文件，因此想知道上述方法是否有可能

P.S.: I tried with calling other feature file using table approach. However, I want to keep one feature file per API, hence want to know if there is any way possible for the above approach

推荐答案

我认为您错过了嵌入式表达式，在许多情况下，它比set关键字简单，尤其是从文件中读取时.

I think you have missed embedded expressions which is simpler than the set keyword in many cases, especially when reading from files.

例如:

request.json -> { wheels : '#(wheels)', color: '#(color)' }

然后这将起作用:

* def wheels = 4
* def color = 'blue'
* def reqJson = read('request.json')
* match reqJson == { wheels: 4, color: 'blue' }

如果您通过演示示例，您将获得很多其他想法.例如:

If you go through the demo examples you will get plenty of other ideas. For example:

* table rows
| wheels | color  | result |
|      4 | 'blue' | 'car'  |
|      2 | 'red'  | 'bike' |

* call read('make-request.feature') rows

其中make-request.feature是:

Given path ''
And request { wheels: '#(wheels)', color: '#(color)' }
When method POST
Then status 200
And match response contains { mode: '#(result)' }
