C# 如何在gherkin中实现techtalk.specflow中的数据表
我需要在小黄瓜中实现数据表。但它们只允许表而不允许数据表。如何在小黄瓜中实现数据表 我试过: 这是我的小黄瓜语法C# 如何在gherkin中实现techtalk.specflow中的数据表,c#,datatable,specflow,gherkin,C#,Datatable,Specflow,Gherkin,我需要在小黄瓜中实现数据表。但它们只允许表而不允许数据表。如何在小黄瓜中实现数据表 我试过: 这是我的小黄瓜语法 Scenario: Select Even Numbers From The list Given Num List | num | | 1 | | 2 | | 3 | | 4 | | 5 | | 6 | | 7 | | 8 | | 9 | | 10 | Then the result should even numbers only o
Scenario: Select Even Numbers From The list
Given Num List
| num |
| 1 |
| 2 |
| 3 |
| 4 |

Then the result should even numbers only on the screen.
这是生成步骤定义后的代码。这里的函数参数是Table(如何将可能的数据表替换为Table?)
表格类型是用小黄瓜表示表格的类型。
如果您直接想要一个DataTable作为函数的参数,可以使用步骤参数转换() 在您的情况下,它必须看起来像这样:
[Binding]
public class Transforms
{
[StepArgumentTransformation]
public DataTable TransformToDataTable(Table booksTable)
{
//your code to put the data from the Table to the DataTable
}
}
用表中的数据填充DataTable仍然需要您完成。您可以将其作为TechTalk.SpecFlow.table类的扩展方法来实现,并利用C#中的一点类反射来简化使用:
namespace YourTestProject
{
public static class SpecFlowTableExtensions
{
public static DataTable ToDataTable(this Table table, params Type[] columnTypes)
{
DataTable dataTable = new DataTable();
TableRow headerRow = table.Rows[0];
int headerCellCount = headerRow.Count();
for (int i = 0; i < headerCellCount; i++)
{
string columnName = headerRow[i];
Type columnType = columnTypes[i];
dataTable.Columns.Add(columnName, columnType);
}
foreach (var row in table.Rows.Skip(1))
{
var dataRow = dataTable.NewRow();
for (int i = 0; i < headerCellCount; i++)
{
string columnName = headerRow[i];
Type columnType = columnTypes[i];
dataRow[columnName] = Convert.ChangeType(row[i], columnType);
}
dataTable.AddRow(dataRow);
}
return dataTable;
}
public static DataTable ToDataTable(this Table table)
{
return table.ToDataTable<string>();
}
public static DataTable ToDataTable<TColumn0>(this Table table)
{
return table.ToDateTable(typeof(TColumn0));
}
public static DataTable ToDataTable<TColumn0, TColumn1>(this Table table)
{
return table.ToDateTable(typeof(TColumn0), typeof(TColumn1));
}
public static DataTable ToDataTable<TColumn0, TColumn1, TColumn2>(this Table table)
{
return table.ToDateTable(typeof(TColumn0), typeof(TColumn1), typeof(TColumn2));
}
}
}
以及步骤定义:
[Given(@"...")]
public void GivenNumList(Table table)
{
DataTable dataTable = table.ToDataTable<int>();
// dataTable.Rows[0]["num"] is an int
}
步骤定义为:
public void GivenSomeList(Table table)
{
DataTable dataTable = table.ToDateTable<int, string>();
// use it
}
public void GivenSomeList(表格)
{
DataTable=table.ToDateTable();
//使用它
}
按照指定SpecFlow列的顺序指定泛型类型
[Given(@"...")]
public void GivenNumList(Table table)
{
DataTable dataTable = table.ToDataTable<int>();
// dataTable.Rows[0]["num"] is an int
}
Given some list
| age | name |
| 2 | Billy |
| 85 | Mildred |
public void GivenSomeList(Table table)
{
DataTable dataTable = table.ToDateTable<int, string>();
// use it
}
