The HttpResponseBase class is an abstract class that contains the same members as the HttpResponse class. The HttpResponseBase class enables you to create derived classes that are like the HttpResponse class, but that you can customize and that work outside the ASP.NET pipeline. When you perform unit testing, you typically use a derived class to implement members that have customized behavior that fulfills the scenario you are testing.

The HttpResponseWrapper class derives from the HttpResponseBase class. The HttpResponseWrapper class serves as a wrapper for the HttpResponse class. At run time, you typically use an instance of the HttpResponseWrapper class to call members of the HttpResponse object.
