The answer to the StatusCode problem is to implement the cast operator to create a HttpWebResponse around your fake WebResponse. Unfortunately, that’s messing around in internal code. You can get there through reflection, but it’s ugly.

Awesomely useful post for unit testers. Unfortunately, my ObjectUnderTest gets a HttpWebReponse and checks the StatusCode, which is read-only and not override-able.

Here’s a quick example which posts some data to a url and get the response. You can test the input in TestWebRequest.GetRequestStream.

public void DoStuff()
{
WebRequest request = WebRequest.Create(this.Url);
request.Method = “POST”;
request.ContentType = “application/x-www-form-urlencoded”;

// Create the data we want to send
string token = “tokenValue”;
string method = “handle”;

string format = “token={0}&method={1}&xml={2}”;
string data = string.Format(CultureInfo.InvariantCulture, format, HttpUtility.UrlEncode(token), HttpUtility.UrlEncode(method), HttpUtility.UrlEncode(GeneratePayload()));

byte[] byteData = UTF8Encoding.UTF8.GetBytes(data.ToString());
request.ContentLength = byteData.Length;

using (Stream postStream = request.GetRequestStream())
{
postStream.Write(byteData, 0, byteData.Length);
}

using (WebResponse response = request.GetResponse())
{
// Do something with the response
}
}

Have you got an example of the code inside ObjectUnderTest
