使用黃瓜在Hypledger Composer中測試概念類型

Question

如果您有地址概念（如演示here），那麼如何編寫黃瓜功能來解釋資產上的所需地址概念？我看到如何使用factory.newConcept（）的mocha.js示例來做到這一點，但是可以使用黃瓜來實現這一點嗎？

And I have added the following assets of type org.acme.Address 
     | addressId | street1   | city | state | zipcode | 
     | AddressA | 123 West 3rd | Anywhere | Texas | 12345 | 
     | AddressB | 123 West 3rd | Anywhere | Texas | 12345 | 
    And I have added the following assets of type org.acme.Delivery 
     | loadId | start | end | 
     | 1  | AddressA | AddressB | 
     | 2  | AddressA | AddressB | 

模型確定指標：

concept Address { 
    o String street1 
    o String street2 optional 
    o String city 
    o String state 
    o String zipcode 
    o Double latitude optional 
    o Double longitude optional 
} 

asset Delivery identified by loadId { 
    o String loadId 
    o Address start 
    o Address end 
} 

我試圖傳遞的參數的散列開始列，但沒有工作，並收到錯誤

ValidationException：型號違反實例org.acme.Delivery＃1 class org.acme.Address具有值的addressConcept期望資源或 概念。

使用Cucumber測試複雜數據時，您需要使用JSON而不是數據表格式。這裏有一個例子：

https://github.com/hyperledger/composer/blob/master/packages/composer-cucumber-steps/features/assets.feature#L14

Scenario: given I have added the following asset 
    Given I have added the following asset 
     """ 
     {"$class":"org.acme.sample.SampleAsset", "assetId":"1", "owner":"alice@email.com", "value":"10"} 
     """ 
    Then I should have the following asset 
     """ 
     {"$class":"org.acme.sample.SampleAsset", "assetId":"1", "owner":"alice@email.com", "value":"10"} 
     """ 

只要你看到一個數據表，你應該能夠提供JSON代替 - 包括數組：

https://github.com/hyperledger/composer/blob/master/packages/composer-cucumber-steps/features/assets.feature#L34

Scenario: given I have added the following assets 
    Given I have added the following assets 
     """ 
     [ 
      {"$class":"org.acme.sample.SampleAsset", "assetId":"1", "owner":"alice@email.com", "value":"10"}, 
      {"$class":"org.acme.sample.SampleAsset", "assetId":"2", "owner":"bob@email.com", "value":"20"} 
     ] 
     """ 
    Then I should have the following assets 
     """ 
     [ 
      {"$class":"org.acme.sample.SampleAsset", "assetId":"1", "owner":"alice@email.com", "value":"10"}, 
      {"$class":"org.acme.sample.SampleAsset", "assetId":"2", "owner":"bob@email.com", "value":"20"} 
     ] 
     """ 

Answer 2

西蒙的回答是好的，但實際上並沒有回答被問到的問題（儘管它在某種程度上是這樣做的）。

如果我可以，我想帶刺（我假設org.acme被命名空間）：你需要

小黃瓜看起來是這樣的：

Scenario: given I have added the following asset 
    Given I have added the following asset 
    """ 
    {"$class":"org.acme.Delivery", "loadId":"1", "start":{"$class":"org.acme.Address", "addressId":"AddressA", "street1":"123 West 3rd", "city":"Anywhere", "state": "Texas", "zipcode":"12345"}, "end":{"$class":"org.acme.Address", "addressId":"AddressB", "street1":"123 West 3rd", "city":"Anywhere", "state": "Texas", "zipcode":"12345"}} 
    """ 
    Then I have added the following asset 
    """ 
    {"$class":"org.acme.Delivery", "loadId":"1", "start":{"$class":"org.acme.Address", "addressId":"AddressA", "street1":"123 West 3rd", "city":"Anywhere", "state": "Texas", "zipcode":"12345"}, "end":{"$class":"org.acme.Address", "addressId":"AddressB", "street1":"123 West 3rd", "city":"Anywhere", "state": "Texas", "zipcode":"12345"}} 
    """ 

通知的嵌套使用標準JSON嵌套語法的地址對象。

同樣，我認爲Simon的回答很好，但如果你不是JSON專家，那麼將他的答案（完全不同的場景）延伸到被問到的問題可能會有挑戰性。

除了開始和結束地址相同（並且12345在德克薩斯州不是有效的郵政編碼）這一事實之外，這應該回答所問的確切問題。
