Abort web test if an error occurs

Using the VS2010 Load Test feature with recorded web tests.

I am having problems with cascading errors on my recorded websites. That is, if one request fails, several other requests will also fail. This creates a lot of clutter in the logs as usually only the first error matters.

Is there a way to make the erroneous validation rule complete the web test at the point of failure and NOT run the rest of the requests?

(to be clear, I still want to continue the load test altogether, just stop this particular iteration of this particular test case)

Here's some sample code that demonstrates what I'm trying to do:

using System.ComponentModel;
using Microsoft.VisualStudio.TestTools.WebTesting;

namespace TestPlugInLibrary
{
    [DisplayName("My Validation Plugin")]
    [Description("Fails if the URL contains the string 'faq'.")]
    public class MyValidationPlugin : ValidationRule
    {
        public override void Validate(object sender, ValidationEventArgs e)
        {
            if (e.Response.ResponseUri.AbsoluteUri.Contains("faq"))
            {
                e.IsValid = false;
                // Want this to terminate the running test as well.
                // Tried throwing an exception here, but that didn't do it.
            }
            else
            {
                e.IsValid = true;
            }
        }
    }
}

I found a good solution. There's a blog here that details it in detail, but the short version is to use e.WebTest.Stop (). This interrupts the current iteration of the current test while leaving the rest of the run.

Use Assert.Fail () . This will stop the test and throw an AssertFailedException just like any failed assertion.

if (e.Response.ResponseUri.AbsoluteUri.Contains("faq"))
{
    e.IsValid = false;
    Assert.Fail("The URL contains the string 'faq'.");
}


This will only stop the specific test. At the end of the load test, you can see that the total number of tests failed with this exception.
