copied!<p>Unfortunately, this isn't particularly easy to do, as the HttpApplication doesn't lend itself to mocking very easily; there is no interface to mock against and most of the methods aren't marked as virtual.</p> <p>I recently had a similar problem with HttpRequest and HttpWebResponse. In the end, the solution I went for was to create a straight "pass-through" wrapper for the methods I wanted to use:</p> <pre><code>public class HttpWebRequestWrapper : IHttpWebRequestWrapper { private HttpWebRequest httpWebRequest; public HttpWebRequestWrapper(Uri url) { this.httpWebRequest = (HttpWebRequest)HttpWebRequest.Create(url); } public Stream GetRequestStream() { return this.httpWebRequest.GetRequestStream(); } public IHttpWebResponseWrapper GetResponse() { return new HttpWebResponseWrapper(this.httpWebRequest.GetResponse()); } public Int64 ContentLength { get { return this.httpWebRequest.ContentLength; } set { this.httpWebRequest.ContentLength = value; } } public string Method { get { return this.httpWebRequest.Method; } set { this.httpWebRequest.Method = value; } } public string ContentType { get { return this.httpWebRequest.ContentType; } set { this.httpWebRequest.ContentType = value; } } } </code></pre> <p>etc, etc</p> <p>This let me mock against my own wrapper interface. Not necessarily the most elegant thing in the world, but a very useful way of mocking out some of the less "mockable" parts of the framework.</p> <p>Before you rush off and do this though, it is worth reviewing what you've got and seeing if there is a better approach to your tests that would avoid you having to wrap classes.</p> <p>In the case of HttpWebRequest, HttpApplication et al, there often isn't IMHO.</p> <p>In order to set this wrapper in mock (using my HttpWebRequest example above) you then do stuff like this with Moq:</p> <pre><code>var mockWebRequest = new Mock<IHttpWebRequestWrapper>(); mockWebRequest.SetupSet<string>(c => c.Method = "POST").Verifiable(); mockWebRequest.SetupSet<string>(c => c.ContentType = "application/x-www-form-urlencoded").Verifiable(); mockWebRequest.SetupSet<int>(c => c.ContentLength = 0).Verifiable(); </code></pre>
