使用 Cucumber 在 Hyperledger Composer 中测试概念类型

Question

如果您有地址概念（如 here 所示），那么您将如何编写黄瓜功能来说明资产上所需的地址概念？我看到如何使用 factory.newConcept() 在 mocha.js 示例中做到这一点，但是是否可以使用黄瓜来完成它？

  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    |

模型定义：

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
}

我曾尝试在起始列中传递参数的哈希值，但没有成功并收到错误

ValidationException: Model violation in instance org.acme.Delivery#1 class org.acme.Address has value addressConcept expected a Resource or a Concept.

使用 Cucumber 测试复杂数据时，需要使用 JSON 而不是数据 table 格式。这里有一个例子：

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"}
        """

无论您在何处看到数据 table，您都应该能够提供 JSON——包括数组：

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"}
        ]
        """

Simon 的回答很好，但实际上并没有回答所问的问题（尽管它以一种迂回的方式回答）。

如果可以的话，我想尝试一下（我假设 org.acme 是命名空间）：

你需要的小黄瓜是这样的：

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"}}
    """

请注意使用标准 JSON 嵌套语法的 nested 地址对象。

同样，我认为 Simon 的回答很好，但如果您不是 JSON 专家，将他的回答（针对完全不同的场景）扩展到被问到的问题可能具有挑战性。

除了开始地址和结束地址相同这一事实（并且 12345 在德克萨斯州不是有效的邮政编码）之外，这应该回答了所问的确切问题。
