PreWebTestEventArgs Class

 

Provides data for the WebTest::PreWebTest event.

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

System::Object
  System::EventArgs
    Microsoft.VisualStudio.TestTools.WebTesting::PreWebTestEventArgs

public ref class PreWebTestEventArgs : EventArgs

NameDescription
System_CAPS_pubpropertyWebTest

Gets the WebTest object that is about to start and caused the PreWebTest event.

NameDescription
System_CAPS_pubmethodEquals(Object^)

(Inherited from Object.)

System_CAPS_protmethodFinalize()

(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

(Inherited from Object.)

System_CAPS_pubmethodGetType()

(Inherited from Object.)

System_CAPS_protmethodMemberwiseClone()

(Inherited from Object.)

System_CAPS_pubmethodToString()

(Inherited from Object.)

This specifically provides a reference to the WebTest that invoked the PreWebTest event.

Legacy Code Example

The following example shows a Web performance test plug-in that adds a random number to the context before the Web performance test is run. After the Web performance test has run, the plug-in displays the length of the last WebTestResponse.

Note the use of the PreWebTestEventArgs in providing a reference to the WebTest.

using System;
using Microsoft.VisualStudio.TestTools.WebTesting;
using System.Windows.Forms;

namespace WebTestPluginNamespace
{
    public class MyWebTestPlugin : WebTestPlugin
    {
        public static string NewRandomNumberString(int size)
        {
            byte[] buffer = new byte[size];
            // Seed using system time
            Random random = new Random(unchecked((int)DateTime.Now.Ticks));

            random.NextBytes(buffer);
            return BitConverter.ToInt32(buffer, 0).ToString();
        }

        public override void PreWebTest(object sender, PreWebTestEventArgs e)
        {
            e.WebTest.Context["RandNum"] = NewRandomNumberString(4);
        }
        public override void PostWebTest(object sender, PostWebTestEventArgs e)
        {
            MessageBox.Show(e.WebTest.LastResponse.ContentLength.ToString());
        }
    }
}
