空手道框架 - 如何检查匹配中的条件 OR 包含响应

问题描述

我正在尝试使用匹配包含来验证我的架构响应和数据类型，例如，有时它返回一个空值，有时它会返回一个字符串.我正在尝试以下操作，但我的断言失败了，因为它没有评估为真.

I am trying to use a match contains to verify my schema response and data types and sometimes it returns a null and sometimes it will return a string, as an example. I am trying the following but I am getting the assertion failed because it did not evaluate to true.

我正在尝试以下操作:

* match each $response.data.Results contains

        """
        {
        "providerID": '#number',
        "firstName": "#? _ == '#string' || _ == '#null'",
        "lastName": '#string',
        "mI": "#? _ == '#string' || _ == '#null'",
        "title": '#string',
        "name": '#string',
        "nameLFMT": '#string',
        "status": '#string',
        "specialties": '#array',
        "locations": '#array',
        "institutions": '#array',
        "acceptNewPatient": '#string',
        "imageUri": '#string',
        "nearestLatitude": '#number',
        "nearestLongitude": '#number'
        }

            """

例如为firstName"返回的数据是firstName":null，

The data returned for "firstName" for example is "firstName":null,

在比赛开始之前，我会发送这个:

Prior to the match each I am sending this:

Scenario: SearchResults
  #Verify 200 response status returned
Given text query =
        """
     {
                  Results: getSearchResults(searchLatitude:"48.942833",
                        searchLongitude: "-119.984549",
                        providerType: "Primary Care Physicians",
                        sortBy: "distance",
                        maxDistance:"600",
                        skip: 0,
                        take: 10) {
                                        providerID
                                        firstName
                                        lastName
                                        mI
                                        title
                                        name
                                        nameLFMT
                                        status
                                        specialties
                                        locations
                                        institutions
                                        acceptNewPatient
                                        imageUri
                                        nearestLatitude
                                        nearestLongitude
                        }

    }

        """

And request { query: '#(query)' }
When method post
Then status 200

我没有定义架构，我还没有弄清楚如何做到这一点，所以我不确定这是否是我的问题.我知道这可能是我应该这样做的方式，但我仍在学习.

I am not defining the schema, I have yet to figure out how to do this so I am not sure if that is my issue. I know this is probably how I should do this but I'm still learning.

感谢您的帮助.

推荐答案

好的，我在这里看到一个问题:

Ok I see one problem here:

"firstName": "#? _ == '#string' || _ == '#null'"

那是行不通的.#? 后面的部分必须是有效的 JavaScript 表达式.如果您不熟悉 JS 但 #string 和朋友特定于空手道 match 关键字并且not 某些东西，这可能很难理解在 JavaScript 中工作.

That's not going to work. The part that follows the #? has to be a valid JavaScript expression. This may be hard to understand if you are not familiar with JS but #string and friends are specific to the Karate match keyword and not something that works in JavaScript.

所以上面这行代码的作用是检查 firstName 的 value 是否等于文字字符串 #string.

So what the above line is doing is checking if the value of firstName is equal to the literal string #string.

幸运的是空手道有一个解决方案:(参考文档'模糊匹配'):

Fortunately Karate has a solution: (refer doc for 'fuzzy matching'):

"firstName": "##string"

这很方便，双 ## 表示可选"，它将匹配 both 字符串或 null.

Which is a convenience, the double ## means 'optional' that will match for both a string or null.
