如何测试GraphQl API? [英] How to test a GraphQl API?

问题描述

我需要编写一个功能测试套件(它将测试GraphQl API).测试套件将与API放在单独的存储库和容器中.

I need to write a functional test suite (that will test a GraphQl API). The test suite will be in a separate repo and container from the API.

我想到的一种方法是在测试套件中使用BDD框架.该套件将在收到HTTP请求后运行所有BDD测试.

One approach I thought of would be to use a BDD framework within the test suite. The suite would run all the BDD tests after receiving a HTTP request.

我正在考虑将Cucumber.js用作BDD框架.我知道有npm test.我不确定如何执行测试.以这种方式使用单元测试框架有点尴尬.这种方法有意义吗?

I was considering using Cucumber.js as the BDD framework. I know there is npm test. I am not sure how I will execute the tests. It feels a bit awkward to use a unit testing framework in this way. Does this approach make sense?

存在哪些工具可以执行此类操作?我愿意考虑各种语言和工具.

What tooling exists to do something like this? I am open to consider various languages and tools.

推荐答案

空手道是一个相对较新的由于2种特定功能，Web服务测试自动化框架恰好非常适合测试GraphQL响应

Karate is a relatively new web-services test-automation framework that happens to be well suited for testing GraphQL responses because of 2 specific capabilities

• 文本操作:内联GraphQL查询，从(可重复使用的)文件和这是一个很好的例子: graphql.feature ，下面是一个摘要:

  Here is a good example: graphql.feature with a snippet below:

  # you can also read this query from a file
  Given text query =
  """
  {
    pokemon(name: "Pikachu") {
      id
      number
      name
      attacks {
        special {
          name
          type
          damage
        }
      }
    }
  }
  """
  And request { query: '#(query)' }
  When method post
  Then status 200
  
  # json-path makes it easy to focus only on the parts you are interested in
  # which is especially useful for graph-ql as responses tend to be heavily nested
  * match $.data.pokemon.number == '025'
  
  # the '..' wildcard is useful for traversing deeply nested parts of the json
  * def attacks = get[0] response..special
  * match attacks contains { name: 'Thunderbolt', type: 'Electric', damage: 55 }
  

  对于非Java团队，空手道提供了二进制可执行文件仅需要JRE，Visual Studio代码为足以作为IDE .由于空手道如何嵌入JavaScript运行时，JavaScript程序员会特别有宾至如归的感觉.支持宽大" JSON(无需双引号，无需将JSON键括在引号中).

  For non-Java teams, Karate provides a binary executable that only requires the JRE, and Visual Studio Code is sufficient as an IDE. JavaScript programmers will especially feel at home because of how Karate embeds a JavaScript runtime and supports 'lenient' JSON (no double-quotes needed, no need to enclose JSON keys in quotes).
