say BDD的基本原则是:

一个场景,一个行为!

这是伟大的,但事实是,我有一个单一的行动,将触发许多不同的事情在系统中。。我必须核实一下会发生的。这是我的小黄瓜:

Scenario: Buying a single product to be delivered now
    Given I am in the checkout page 
    When I checkout the order
    Then the order should be created to the specified address 
    And the order should be set in pending state
    And ops must be notified via a slack notification
    And A shopper must be auto assigned the order via a push notification
    And A retailer must be notified about the order via a push notification 
    And A transaction must be recorded in the payment gateway
    And My wallet should be deducted by the payment amount

这看起来真难看。但现在我不知道怎么把它分开。做一个 什么时候 然后配对(我用的是Behat, which has 一鉴于 , 和在每个场景中(在背景之后)。

建议?

除了@Stratadox的答案(按行为划分场景)- Given 步骤不应涉及用户界面或用户旅程中的某个阶段。用户所在的页面与业务逻辑无关。

鉴于 步骤(如 Arrange 步进单元测试)用于在给定状态下设置系统。这个州建立在 鉴于 Then 步进)

例如:

那么 步骤)。

鉴于 与此场景的结果直接相关的步骤

Scenario: Being charged the correct amount on successful purchase of product
   Given I have Â£10 in my wallet
   When I purchase a Toaster Oven for Â£4
   Then I should have Â£6 left in my wallet

“购物者必须通过推送通知自动分配订单”-这是可以作为“成功购买”检查的一部分断言的结果。唯一取决于购买是否成功。您可以将诸如“购物者通知,零售商通知交易记录”之类的断言捆绑在一起,并在您的场景中为它们指定一个名称和一行,例如:

Given Jon has the following items in his basket:
  | Macbook Pro | Â£3000 |
When Jon checks out his basket
Then a purchase of "xyz" for Â£3000 by Jon should have gone through

解决这一问题最直接的方法是遵循您在问题中引用的建议:

一个场景,一个行为!

要实现这个建议,只需将臃肿的场景拆分为多个较小的场景。

Scenario: Buying a single product to be delivered now
    Given I am in the checkout page 
    When I checkout the order
    Then the order should be created to the specified address 
    And the order should be set in pending state

Scenario: Notifying ops of the purchase
    Given I am in the checkout page 
    When I checkout the order
    Then ops must be notified via a slack notification

…等等。

许多 given

您甚至可以更进一步,考虑将它们分组为不同的功能。

毕竟,通知ops是另一回事特征
