KarateAPI中有类似POJO的功能吗? [英] Having a POJO like feature in KarateAPI?

问题描述

一段时间以来，我一直在使用空手道和RestAssured.当然，这两种工具都有其优点和缺点.现在，我有一个RestAssured项目，其中有请求和响应"对象以及POJO.我的请求包装了我的端点，并将我的POJO发送到那些端点.我在抽象层中完成所有Header等配置.如果需要覆盖它们，则在测试期间覆盖它们.如果没有，那么我需要两行代码来触发端点.

I have been using Karate and RestAssured for sometime. There are advantages and downside of both tools of course. Right now I have a RestAssured project where I have Request and Response object and POJOs. My requests wraps my endpoint and send my POJOs to those endpoint. I do all my Headers, etc configuration in an abstract layer. In case I need to override them, I override them during the test. If not, Its a two lines of code for me to trigger an endpoint.

我使用edpoint的快乐路径和负路径的方式是，在每次测试之前，我都使用构造函数中的新值初始化POJO.然后，我将覆盖测试范围中想要的值.例如，如果要测试否定的密码字段，请在测试过程中将此字段设置为空字符串.但是在测试之前，其他字段已经设置为一些随机的东西.

My way of working with happy path and negative path of an edpoint is that I initialize the POJO before every test with new values in the constructor. Then I override the value that I want in test scope. For example, if I want to test a negative case for password field, I set this field to empty string during the test. But other fields are already set to some random stuff before the test.

但是我不知道如何用空手道来做到这一点.

But I dont know how to achieve this with Karate.

空手道允许我创建请求正文的JSON表示并定义我的参数，如下面的示例所示.

Karate allows me to create a JSON representation of my request body and define my parameters as seen below example.

    {
  "firstName": "<name>",
  "lastName": "<lastName>",
  "email": "<email>",
  "role": <role>
  }

然后在每次测试中，我都必须用一些数据填充所有字段.

Then in every test I have to fill all the fields with some data.

 |token    |value|
  |name     |'canberk'|
  |lastName |''|
  |email    |'[e-mail]'|
  |role     |'1'|

和

|token    |value|
      |name     |''|
      |lastName |'akduygu'|
      |email    |'[e-mail]'|
      |role     |'1'|

它是这样的.

使用4个字段的JSON正文是可以的，但是当该正文开始具有20多个字段时，很难为每个测试初始化​​每个字段.

It's ok with a 4 fields JSON body but when the body starts to have more than 20 fields, it become a pain to initialise every field for every test.

空手道是否可以通过预定义的步骤来解决此问题，我需要提出解决方案?

Does Karate have a way of achieving this problem with a predefined steps of I need to come up with a solution?

推荐答案

这两种工具都有优点和缺点.

There are advantages and downside of both tools of course.

我肯定有偏见，但是恕我直言，与REST相比，空手道的唯一缺点是您没有获得编译时安全性:)我希望您已经看过

I'm definitely biased, but IMHO the only disadvantage of Karate compared to REST-assured is that you don't get compile time safety :) I hope that you have seen this comparison.

空手道有多种方法来做您想做的事.这就是我要做的.

Karate has multiple ways to do what you want. Here's what I would do.

1. 创建一个设置了所有快乐路径"值的JSON文件
2. 使用read()语法加载文件(这意味着该文件可在多个测试中重复使用)
3. 使用set关键字仅更新您的方案或否定测试的字段

1. create a JSON file that has all your "happy path" values set
2. use the read() syntax to load the file (which means this is re-usable across multiple tests)
3. use the set keyword to update only the field for your scenario or negative test

如果使用嵌入式表达式，您将获得更多的乐趣.

You can get even more fancier if you use embedded expressions.

1. 创建一个设置了所有快乐路径"值的JSON文件，您想要更改的值看起来像foo: '##(foo)'
2. 在使用read()之前，您需要初始化一些变量，例如* def foo = 'bar'，如果您使用null，则该JSON密钥甚至会从JSON中删除
3. read() JSON.准备使用了！

1. create a JSON file that has all your "happy path" values set and the values you want to vary look like foo: '##(foo)'
2. before using read() you init some variables for e.g. * def foo = 'bar' and if you use null that JSON key will even be removed from the JSON
3. read() the JSON. it is ready for use !

您可以参考此文件，其中演示了XML的一些概念，您可能会得到更多的想法:
