WebTestRequest 类

项目

更新：2007 年 11 月

表示将发送到 Web 服务器的 HTTP 请求。

命名空间： Microsoft.VisualStudio.TestTools.WebTesting
程序集： Microsoft.VisualStudio.QualityTools.WebTestFramework（在 Microsoft.VisualStudio.QualityTools.WebTestFramework.dll 中）

语法

声明
<SerializableAttribute> _
Public Class WebTestRequest _
    Inherits WebTestItem
用法
Dim instance As WebTestRequest

[SerializableAttribute]
public class WebTestRequest : WebTestItem

[SerializableAttribute]
public ref class WebTestRequest : public WebTestItem

public class WebTestRequest extends WebTestItem

备注

此类为模拟编码 Web 测试中的 HTTP 请求提供了核心功能。Visual C# Web 测试的 GetRequestEnumerator 方法和 Visual Basic 中的 ThreadedWebTest 所使用的 Run 方法将模拟 HTTP 请求返回到 Web 测试引擎。

此类是可序列化的。

示例

下面的 Web 测试提取表示复选框状态的值，并将这些值添加到上下文。

namespace TestProject1
{
    using System;
    using System.Collections.Generic;
    using Microsoft.VisualStudio.TestTools.WebTesting;
    using ClassLibrary2;

    public class MyWebTest : WebTest
    {
        public MyWebTest()
        {
            this.PreAuthenticate = true;
        }

        public override IEnumerator<WebTestRequest> GetRequestEnumerator()
        {
            WebTestRequestrequest1 = new WebTestRequest("https://localhost/ts");
            ExtractCheckBoxes rule1 = new ExtractCheckBoxes();
            rule1.FindCheckedBoxes = true;
            rule1.ContextParameterName = "CheckedBoxes";
            request1.ExtractValues += new EventHandler
                <ExtractionEventArgs>(rule1.Extract);
            ExtractCheckBoxes rule2 = new ExtractCheckBoxes();
            rule2.FindCheckedBoxes = false;
            rule2.ContextParameterName = "";
            request1.ExtractValues += new EventHandler
                <ExtractionEventArgs>(rule2.Extract);
            yield return request1;
        }
    }
}

以下是从 ThreadedWebTest 继承的、名为 MyCodedWebTest 的编码 Web 测试。第二个请求将三个控件中包含的窗体信息回发到服务器。
