黄瓜特征文件-描述聚合

Question

我是黄瓜世界的新手，我只想为我的场景描述一个聚合。我有一个模型和一个类似下面的DataTransferObject，我想写一个REST Api，它返回一个JSON。

public class Product {
  int id;
  String name;
  double basePrice;
  ProductCategory category;
}

public class ProductCategory {
  int id;
  String name;
  List<Customization> possibleCustomizationsForCategory;
}

public class Customization {
  int id;
  String characteristic;
  double additionalPrice;
}

public class ProductDTO {
  int productId;
  String productName;
  double basePrice;
  Size size;
  int productCategoryId;
  String productCategoryName;
  List<Integer> possibleCustomizationIds;
}

我想写这样的东西：

Given the system has persisted the following products
When a client requests GET /products
Then he will receive a JSON like the following:
  """
   [
    {
     "productId": 1,
     "productName": "Kaffee",
     "basePrice": 2.00,
     "size": "SMALL",
     "productCategoryId": 1,
     "productCategoryName": "Hot Drinks",
     "possibleCustomizationIds": [1,2,3,4,5,6]
    },
    {
     "productId": 2,
     "productName": "Kaffee",
     "basePrice": 3.0,
     "size": "MEDIUM",
     "productCategoryId": 1,
     "productCategoryName": "Hot Drinks",
     "possibleCustomizationIds": [1,2,3,4,5,6]
    }
    {
     "productId": 3,
     "productName": "Cookie",
     "basePrice": 1.0,
     "size": "SMALL",
     "productCategoryId": 1,
     "productCategoryName": "Biscuite",
     "possibleCustomizationIds": [8,9]
    }
   ]
  """

但是，我如何编写给定的部分并以一种明确的方式描述对象，即存在三个带有聚合的不同类？

Answer 1

我会让Gherkin使用一种更具业务级别的语言来描述您试图解决的问题。

然后，我会让步骤定义描述问题的解决方案。

因此，您的小黄瓜可能是：

Given the following products are in stock
   | Product       |
   | Small Kaffee  |
   | Medium Kaffee |
   | Small Cookie  |
When I get a list of stock
Then I the three products should be shown as in stock
And I should be able to view the details about them

我假设这是一个库存控制的情况。然后，此方案可以针对数据库、web api或GUI运行，并且应该仍然正确，只是需要一个不同的解决方案。即使用不同的步骤定义。
