PreWebTestEventArgs Class

Provides data for the PreWebTest event.

Namespace: Microsoft.VisualStudio.TestTools.WebTesting
Assembly: Microsoft.VisualStudio.QualityTools.WebTestFramework (in microsoft.visualstudio.qualitytools.webtestframework.dll)

public class PreWebTestEventArgs : EventArgs
public class PreWebTestEventArgs extends EventArgs
public class PreWebTestEventArgs extends EventArgs

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

The following example shows a Web test plug-in that adds a random number to the context before the Web test is run. After the Web 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, PreWebTestEventArgse)
        {
            e.WebTest.Context["RandNum"] = NewRandomNumberString(4);
        }
        public override void PostWebTest(object sender, PostWebTestEventArgs e)
        {
            MessageBox.Show(e.WebTest.LastResponse.ContentLength.ToString());
        }
    }
}
