空手道:比较CSV数据和api响应 [英] Karate: compare csv data with api response

问题描述

我有一个用例，我想对API响应进行断言，并将其与csv数据进行比较.

I have a use case where I want to assert on a API response and compare it with the csv data.

第一步:

Csv file: *test.csv*
id,date,fullname,cost,country,code
1,02-03-2002,user1,$200,Canada,CAN
2, 04-05-2016,user2,$1500,United States, USA

我读取了csv文件并将其存储在变量中

I read the csv file and store it in a variable

• def var1 =读取(test.csv)

所以现在，var1是基于我的csv的json列表

So now, var1 is a list of jsons based on my csv

var1 = [
{
"id":1,
"date":"02-03-2002",
"fullname": "user1",
"cost": "$200",
"country": "Canada",
"code": "CAN"
},
{
"id":2,
"date":"04-05-2016",
"fullname": "user2",
"cost": "$1500",
"country": "United States",
"code": "USA"
}
]

第2步: 我打了我的api并得到了回应

Step2: I hit my api and get a response

Given url "https://dummyurl.com
Given path "/userdetails"
When method get
Then status 200
* def apiResponse = response

第3步: 我的api返回一个列表响应，即:

Step 3: My api returns a list response which is:

{
"id":1,
"date":"02-03-2002",
"fullname": "user1",
"cost": "$200",
"country": { 
  "name": "Canada",
  "code": "CAN"
  }
},
{
"id":2,
"date":"05-04-2012",
"fullname": "user2",
"cost": "$1500",
"country": { 
  "name": "United States",
  "code": "USA"
  }
},
...and more 100 records..
]

第4步: 因此，我现在要执行两个断言

Step 4: So there are two assertions now which I wanted to perform

1. 获取csvresponse和apiresponse的计数，并使用 .length 运算符

其次，我想确认每个csv记录是否与每个api响应匹配. 如果可能的话，来自csv和apiresponse的 id 键是主键，因此，如果我可以迭代id并匹配api响应以解决任何差异.

Secondly, I want to confirm if each csv records are matching with each api response. And if possible in my case id key from csv and apiresponse is primary key, so if I can iterate on id and match the api response for any discrepancy.

请让我知道您是否可以理解此方法，以及是否能够解释我的用例. 感谢您的早日答复.

Let me know if this is readable for you and if I was able to explain my use case. Thanks for your earlier response.

推荐答案

请阅读match contains语法，这就是您所需要的:

Please read up on the match contains syntax, that's all you need: https://github.com/intuit/karate#match-contains

所以这一行就足够了:

* match var1 contains response

如果新的contains deep有帮助，也请查看以下答案: https://stackoverflow.com/a/63103746/143475

Also look at this answer in case the new contains deep helps: https://stackoverflow.com/a/63103746/143475

尽量避免重复，大多数API测试都不需要它.但是您当然可以做到.查看以下答案:

Try to avoid iterating, it is not needed for most API tests. But you can certainly do it. Look at these answers:

也请阅读此内容-因为我怀疑您正在尝试使测试过于复杂.请不要.在100％确定形状"正确的地方编写测试.尽可能多的响应: https://stackoverflow.com/a/54126724/143475

Also read this - because I suspect you are trying to over-complicate your tests. Please don't. Write tests where your are 100% sure of the "shape" of the response as far as possible: https://stackoverflow.com/a/54126724/143475

并且请阅读文档.值得.

And please please read the docs. It is worth it.
