Namespace:  Microsoft.VisualStudio.TestTools.WebTesting
Assembly:  Microsoft.VisualStudio.QualityTools.WebTestFramework (in Microsoft.VisualStudio.QualityTools.WebTestFramework.dll)

'Declaration
Public MustOverride Sub Validate ( _
    sender As Object, _
    e As ValidationEventArgs _
)
public abstract void Validate(
    Object sender,
    ValidationEventArgs e
)
public:
virtual void Validate(
    Object^ sender, 
    ValidationEventArgs^ e
) abstract

        e:ValidationEventArgs -> unit

Remarks

Validate is called with the test case context and transaction context. These allow the rule to examine both the request and the response and make sure that the data matches the required values.

Examples

The following example validates whether the Web page contains any client script.

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

    public class MyCodedWebTest : WebTest
    {
        public override IEnumerator<WebTestRequest> GetRequestEnumerator()
        {
            WebTestRequest request1 = new WebTestRequest
                ("https://localhost/MyWebSite");
            request1.ThinkTime = 13;
            ExtractHiddenFields rule1 = new ExtractHiddenFields();
            rule1.ContextParameterName = "1";
            request1.ExtractValues += new EventHandler<ExtractionEventArgs>
                (rule1.Extract);
            yield return request1;

            WebTestRequest request2 = new WebTestRequest
                ("https://localhost/MyWebSite/Default.aspx");
            request2.Method = "POST";
            FormPostHttpBody request2Body = new FormPostHttpBody();
            request2Body.FormPostParameters.Add("__VIEWSTATE",
                "{{$HIDDEN1.__VIEWSTATE}}");
            request2Body.FormPostParameters.Add("Button1", "Button");
            request2Body.FormPostParameters.Add("TextBox1",
                "Added Text in form");
            request2.Body = request2Body;
            ValidatePageContainsScript rule2 = new ValidatePageContainsScript();
            request2.ValidateResponse += new EventHandler<ValidationEventArgs>
                (rule2.Validate);
            yield return request2;
        }
    }
