Constructors

Properties

	Name	Description
	Body	Gets or sets the body of this request.
	BodyBytes	Gets the bytes that are associated with the body.
	Cache	Gets or sets a value that indicates whether to simulate browser caching for the request.
	ClientCertificates	Gets or sets a reference to allow users to authenticate by using X.509 SSL certificates.

	Encoding	Gets or sets the Encoding format.
	ExpectedHttpStatusCode	Gets or sets the HTTP status code that is expected for this request.

	Headers	Gets the collection of HTTP headers for the request.
	IsRedirectFollow	Gets a value that indicates whether the request was created as the result of following a redirect.
	ItemId	Zero-based sequence number of the item in the Web performance test. (Inherited from WebTestItem.)

	Outcome	Gets or sets the Pass or Fail outcome of the Web performance test request.
	ParseDependentRequests	Gets or sets a value that indicates whether to automatically fetch dependent requests that are found in the response body.
	QueryStringParameters	Gets the list of query string parameters for the request.
	RecordedCookies	Gets the cookies that is recorded together with the request.
	RecordResult	Gets or sets a value that indicates whether individual statistics and result data are tracked for this request.
	ReportingName	Gets or sets the reporting name for a request.
	ResponseTimeGoal	Gets or sets the response time goal for a particular page.
	SendChunked	Gets or sets a value that indicates whether the user can send a chunked request body.
	ThinkTime	Gets or sets a value that represents the think time to wait after the response is received.
	Timeout	Gets or sets a value that indicates the time to wait for this request before timing out.
	Url	Gets or sets the URL to the resource that is used for the request.

Methods

	Name	Description
	Clone	Makes a deep copy of the WebTestRequest object. (Overrides WebTestItem.Clone().)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	InternalSetOutcome	Represents the outcome that was set internally by RequestPlugin.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	RuntimeClone	Returns a clone of this object at run time. (Inherited from WebTestItem.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Events

	Name	Description
	ExtractValues	Occurs after the ValidateResponse event.
	PostRequest	Occurs after the ValidateResponse and the ExtractValues events.
	PreRequest	Occurs before the request is sent.
	PreRequestDataBinding	This event is raised before the data binding occurs.
	ValidateResponse	Occurs immediately after the response is received.
	ValidateResponseOnPageComplete	This event is raised after the page is fully loaded. This is used to check that the response was valid.

Remarks

This class provides the core functionality to simulate HTTP requests in a coded Web performance test. The simulated HTTP requests are returned to the Web performance test engine by the GetRequestEnumerator method for Visual C# Web performance tests and by the Run method that is used by ThreadedWebTest in Visual Basic.

This class is serializable.

Examples

The following Web performance test extracts values that represent the status of check boxes and adds the values to the context.

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()
        {
            WebTestRequest request1 = 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;
        }
    }
}

The following is a coded Web performance test called MyCodedWebTest that inherits from ThreadedWebTest. The second request posts form information that is contained in three controls back to the server.
