空手道 - 任何不丑陋的方式来发送每个请求正文字段的格式错误请求的 API 请求? [英] Karate- Any non-ugly way to send API requests with malformed requests for each request body field?

问题描述

我有一个奇怪的问题，我已经有了解决方案，但它非常难看.我想知道是否有更好的方法通过空手道或 JS 来做到这一点.我在这两个方面都是新手，所以请多多包涵.

I have a strange problem for which I already have a solution for but it's VERY ugly. I am wondering if there is a better way to do it through Karate or JS. I am new at both so please bear with me.

我正在发送一个带有相当大的请求正文(总共 19 个字段)的 POST 调用.我必须有目的地为每个字段发送格式错误的请求，而不是为键输入合法值，而是放入垃圾值(或完全删除值)并确保按预期返回 400.

I am sending a POST call with a rather large request body (total of 19 fields). I have to purposefully send malformed requests for EACH field where instead of inputting a legitimate value for a key, I am putting garbage values (or removing the value altogether) and making sure I get a 400 back as expected.

例如请求正文如下(为便于说明而缩短):

For example the request body is as follows (shortened for illustration purposes):

{
    "Age": 20
    "School": "UIC"
    "Sex": "Female"
}

我正在发送如下请求:

* def payload = {"Age":'#(age)',"School":'#(schoolName)', "Sex":'#(gender)'}
* copy payload1 = payload
* copy payload2 = payload
* copy payload3 = payload
* remove payload1.Age
* remove payload2.School
* remove payload3.Sex
* table callTable
    |payload  |status|
    |payload1 | 400  |
    |payload2 | 400  |
    |payload3 | 400  |
* call read (call to the actual POST API here)

现在从表面上看，上面可能看起来并不难看，但想象一下对 19 个字段执行此操作，而不是删除，每个字段大约有五个不同的请求(而不是上面只有一个删除").

Now on surface the above may not look ugly but imagine doing that for 19 fields and instead of remove, there is about FIVE different requests PER field (instead of just one "remove" above).

我曾考虑使用 JS 和循环函数，但我知道的不够多，我的尝试失败了.

I have contemplated using JS and a loop function but I don't know enough and my attempts failed spectacularly.

请告知在空手道和/或 JS 中是否有更好的方法.

Please advise if there is a way better to do it in Karate and/or JS.

推荐答案

您可以使用循环来构建 JSON.例如:

You can use a loop to build JSON. For example:

* def keys = ['foo', 'bar', 'baz']
* def body = {}
* keys.forEach(k => body[k] = 'blah')
* match body == { foo: 'blah', bar: 'blah', baz: 'blah' }
