如何在场景大纲中传递specflow示例的负数？

Question

我有这个功能

Feature: Selling Holiday
    As a person selling holiday
    I want to know the bonus per month

Scenario Outline: Selling Holiday
    Given I am selling holiday
    And I have a current salary rate of <rate> pounds an hour
    And I have chosen <hours> hours
    Then the cost should be <cost>

Examples: 
    | rate  | hours | cost  |
    | 9.00  | 14    | -10.2 |
    | 12.00 | 14    | -14   |
    | 8.0   | 7.5   | -5    |

[Then]
public void Then_the_cost_should_be_COST(decimal cost)
{
    //Cost is always positive :(
    Assert.AreEqual(cost, holidayCostCalculator.CalculateCost();
}

问题在于，成本正在以正面而非负面的方式传递到步骤中。

这里有另一个问题，他们通过添加属性解决了这个问题，但这在我看来并不是一个可接受的解决方案，因为它根本不直观。

Answer 1

使用传统的步骤式

[Then(@"the cost should be (.*)")]
public void ThenTheCostShouldBe(Decimal cost)
{
}

另外，为避免输入字符串问题，请从表中的值中删除尾随零：

| rate | hours | cost  |
| 9    | 14    | -10.2 |
| 12   | 14    | -14   |
| 8    | 7     | -5    |

PR submitted来解决此问题。它应该发布2.1版本，我相信它会安排几周。
