c# - 将场景大纲“示例”表解析为对象

Question

我一直在试图弄清楚如何将场景大纲示例解析为（自定义）对象，而无需在步骤名称中显式使用。

Scenario Outline: Customer makes an appointment

Given The user enters details on the page
When The user submits the page
Then The appointment details are shown.

Examples:
| Reason | Firstname | Lastname | Email            |
| A      | John      | Doe      | [e-mail] |
| B      | Jane      | Doe      | [e-mail] |

我现在正在尝试找出如何将示例行解析为自定义约会对象

我一直在用表格查看 CreateInstance，但这似乎不起作用

 [Given(@"The user enters details on the page")]
 public void EnterDetails(Table table)
 {
     var appointment = table.CreateInstance<Appointment>();

     driver.FindElement(By.Id("Firstname")).SendKeys(appointment.Firstname);    
 }

运行此程序时出现错误

Message: TechTalk.SpecFlow.BindingException : Parameter count mismatch! The binding method EnterDetails(Table)' should have 0 parameters

这是预约课

public class Appointment
{
    public AppointmentReason Reason { get; set; }
    public string Firstnam { get; set; }
    public string Lastname { get; set; }
    public string Email { get; set; }
}

谁能指出我正确的方向如何将示例行解析为约会对象？

Answer 1

您没有将任何参数传递给 Given 函数，这就是它引发异常的原因。您可以传入这样的表格：

Scenario Outline: Customer makes an appointment

Given The user enters details on the page
    | Reason   | Firstname   | Lastname   | Email   |
    | <Reason> | <Firstname> | <Lastname> | <Email> |
When The user submits the page
Then The appointment details are shown.

Examples:
| Reason | Firstname | Lastname | Email            |
| A      | John      | Doe      | [e-mail] |
| B      | Jane      | Doe      | [e-mail] |

给定步骤内的尖括号是参数。在这种情况下放置在一个表内。参数取自示例中的表格，因为您使用的是场景大纲。
