契约测试SpringCloud Contract groovy示例

SHILI:

org.springframework.cloud.contract.spec.Contract.make {
  request {
    method 'PUT'
    url '/fraudcheck'
    body("""
    {
      "clientId":"1234567890",
      "loanAmount":99999
    }
    """)
    headers {
      header('Content-Type', 'application/vnd.fraud.v1+json')
    }
  }
response {
  status 200
  body("""
  {
    "fraudCheckStatus": "FRAUD",
    "rejectionReason": "Amount too high"
  }
  """)
  headers {
    header('Content-Type': 'application/vnd.fraud.v1+json')
  }
 }
}

 示例2：

org.springframework.cloud.contract.spec.Contract.make {
    request {
        method 'PUT'
        url '/api/12'
        headers {
            header 'Content-Type': 'application/vnd.org.springframework.cloud.contract.verifier.twitter-places-analyzer.v1+json'
        }
        body '''\
        [{
            "created_at": "Sat Jul 26 09:38:57 +0000 2014",
            "id": 492967299297845248,
            "id_str": "492967299297845248",
            "text": "Gonna see you at Warsaw",
            "place":
            {
                "attributes":{},
                "bounding_box":
                {
                    "coordinates":
                        [[
                            [-77.119759,38.791645],
                            [-76.909393,38.791645],
                            [-76.909393,38.995548],
                            [-77.119759,38.995548]
                        ]],
                    "type":"Polygon"
                },
                "country":"United States",
                "country_code":"US",
                "full_name":"Washington, DC",
                "id":"01fbe706f872cb32",
                "name":"Washington",
                "place_type":"city",
                "url": "http://api.twitter.com/1/geo/id/01fbe706f872cb32.json"
            }
        }]
    '''
    }
    response {
        status OK()
    }
}

示例3：GET请求带parameters参数：例如/product?id=537

import org.springframework.cloud.contract.spec.Contract
Contract.make {
    //ignored()
    request {
        method 'GET'
        urlPath('/product') {
            queryParameters {
                parameter('id', 537)
            }
        }
    }

    response {
        status 200
        body(
                '''
                {
                  "description": "Consumer Test verifies provider",
                  "name": "Consumer Test",
                  "type": "testing product"
                }
                '''
        )
        headers {
            header('Content-Type', 'application/json;charset=UTF-8')
        }
    }
}

 

示例4：

package contracts

org.springframework.cloud.contract.spec.Contract.make {
    request {
        method 'GET'
        url '/abc/def/serviceA?catalog=x'
        body("")
    }
    response {
        status 200
        body(""
        )
        headers {
            contentType(applicationJsonUtf8())
        }
    }
}

header：

        headers {
            header('Content-Type', 'application/json;charset=UTF-8')
            header('myHeader', 'duan')
        }

 

我个人还是比较倾向于使用yaml，主要还是因为yaml语法比较简单，同时，对于90%的契约，其实都是简单型契约，很少会遇到复杂的使用场景，如果你要写一个特别复杂的契约，可能你就需要好好想想如何简化这个契约了。

契约只要组成部分就是 request（method，url，body，headers），response（status，body），我们比较常用的方式是 将request的body和response的body定义成2个json文件，然后，使用fromFile方法直接引用。
groovy 写法

import org.springframework.cloud.contract.spec.Contract

Contract.make {
    request {
        method('PUT')
        headers {
            contentType(applicationJson())
        }
        body(file("request.json"))
        url("/1")
    }
    response {
        status OK()
        body(file("response.json"))
        headers {
            contentType(textPlain())
        }
    }
}

yaml写法

request:
  method: GET
  url: /foo
  bodyFromFile: request.json
response:
  status: 200
  bodyFromFile: response.json

request.json

{ "status" : "REQUEST" }

response.json

{ "status" : "RESPONSE" }
