Provides a means to run code and access a WebTest before and after the Web test is run. This class must be inherited.
(in Microsoft.VisualStudio.QualityTools.WebTestFramework.dll)
Visual Basic (Declaration)
Public MustInherit Class WebTestPlugin
Dim instance As WebTestPlugin
public abstract class WebTestPlugin
public ref class WebTestPlugin abstract
public abstract class WebTestPlugin
Using a WebTestPlugin and using the PreWebTest/PostWebTest events of the WebTest class are functionally equivalent. The difference is that coded Web tests are the only place you can use the events.
Notes to Inheritors:
When you inherit from WebTestPlugin, you must override the following members: PostWebTest, and PreWebTest.
The following example shows a Web test plug-in that adds a random number to the context before the Web test is run. In the same way you can override PostWebTest and perform an action after the Web test has run. For example, you might want to write to a log file the time it takes to complete the Web test and the number of requests issued during the Web test.
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);
}
}
}
