Feature: Order and warehouse testing
Background
Given registered users
| UserId   | Name  | Surname | Mail             | Delivery address | City     |
| AJ       | John  | Red     | j.red@red.com    | Down street      | London   |
| MWitch   | Marck | Witch   | Mark.Witch@gl.it | High street      | New york |

如果过于详细，则背景部分可能太大，您只需要针对多种情况编写所需内容即可。

@Orders
Scenario: An order is submitted

Given, When, Then

Given The warehouse
| Code | Products | Quantity | Unit of measure | Alert threshold |
| P1   | Tomato   | 150      | Box             | 25              |
| V1   | Wine     | 350      | Bottle          | 40              |

When：我们将触发我们要测试的代码的动作放在何处：

When An order arrives
| User | Product | Quantity |
| AJ   | P1      | 2        |
| AJ   | V1      | 1        |

Then：我们将代码运行时需要发生的所有事情放在哪里。

Then The warehouse contains these products
| Code | Product  | Quantity |
| P1   | Tomato   | 148      |
| V1   | Wine     | 349      |Then the Purchasing Office is notified
| Product under threshold | Quantity | Threshold |

或其他情况：

@Order
Scenario: An order is placed that lowers the quantity of the products under the threshold
Given The warehouse
| Code | Products | Quantity | Unit of measure | Alert threshold |
| P1   | Tomato   | 26       | Box             | 25              |
| V1   | Wine     | 350      | Bottle          | 40              |When An order arrives
| Users| Products | Quantity |
| AJ   | P1       | 2        |
| AJ   | V1       | 1        |Then The warehouse contains these products
| Code | Products | Quantity |
| P1   | Tomato   | 24       |
| V1   | Wine     | 349      |Then the Purchasing Office is notified
| Products under threshold | Quantity | Threshold |
| P1                       | 24       | 25        |

代码

[Given(@"registered users")]
public void GivenregisteredUsers(Table table) {foreach (var row in table.Rows){sessionManager.AddRecord(new User{UserId = row["UserId"],Name = row["Name"],Surname = row["Surname"],DeliveryCity = row["City"],DeliveryAddress = row["Delivery address"],Mail = row["Mail"]});}}
}

When 将响应一个代码，该代码将调用我们用于下订单的方法：

[When(@"An order arrives")]
public void WhenAnOrderArrives(Table table)
{OrderCore core = new OrderCore(sessionManager);List<<order>order> = new <List><order>();foreach (var row in table.Rows){order.Add(new Order{User = row["User"],Product = row["Products"],Quantity = Convert.ToDecimal(row["Quantity"]),});}result = core.AcceptOrder(order);
}

使用代码：

public OrderResult AcceptOrder(IEnumerable<order> orders)
{var orderResult = new OrderResult();foreach (var order in orders){var product = sessionManager.Query<product>().Single(x => x.Code == order.Product);product.Quantity = product.Quantity - order.Quantity;sessionManager.SaveOrUpdate(product);if (product.Quantity < product.Threshold)orderResult.AlertThresholds.Add(new OrderResult.AlertThreshold{product = product.Name,Quantity = product.Quantity,Threshold = product.Threshold});}return orderResult;
}

在Then中，我们将放置一些代码来检查是否已产生所需的行为。

[Then(@"The warehouse contains these products")]
public void ThenTheWarehouseContainsTheseProducts(Table table)
{var products = sessionManager.Query<Product>();foreach (var row in table.Rows){var product = products.Where(x => x.Code == row["Code"]).Single();Assert.That(product.Quantity == Convert.ToDecimal(row["Quantity"]));}
}[Then(@"the Purchasing Office is notified")]
public void ThenThePurchasingOfficeIsNotified(Table table)
{if (table.Rows.Count == 0)Assert.That(result.AlertThresholds.Count() == 0);else{Assert.That(result.AlertThresholds.Count() == table.Rows.Count);foreach (var row in table.Rows){var product = result.AlertThresholds.SingleOrDefault(x => x.product == row["Products under threshold"]);Assert.That(product != null);Assert.That(product.Quantity == Convert.ToDecimal(row["Quantity"]));Assert.That(product.Threshold == Convert.ToDecimal(row["Threshold"]));}}
}

在构建解决方案时，Visual Studio将找到测试并将其显示在“测试资源管理器”中，您可以在其中运行它们。
