Testing with MOQ and Session State Wrapper

I'm using a Session wrapper as written below. The problem I have is when running tests the try doesn't work and it goes to the catch so session variables are never being set. I'm using Moq to create a mock Session state for my mock context. If I create a variable like:

Session["variable"] = "something";

That works fine and persists to the end of the test. Everything created for in my wrapper does not. Since the Session is somehow persisting, my theory is just that I need to figure out where it is and then put it in my catch. I don't know how to go about that though. public class MySession { // private constructor private MySession() { id = new Random().Next(100000); }

    // Gets the current session.
    public static MySession Current
    {
        get
        {                
            MySessi开发者_StackOverflow中文版on session = new MySession();
            try
            {
                session =
                (MySession)HttpContext.Current.Session["__MySession__"];
            }
            catch
            {
                //Catch nothing
            }
            if (session == null)
            {
                session = new MySession();
                HttpContext.Current.Session["__MySession__"] = session;
            }
            return session;
        }
    }

    // **** add your session properties here, e.g like this:
    public int id { get; set; }

I feel you've got the wrong end of the stick in the way you've created your session wrapper. A session wrapper normally means you create a class which, in production code, passes all calls to the real session. In unit tests, it does not have a real session inside and could be a mock object. Your MySession class always needs a real session, so any test using will not be a true unit test.

You might not need to roll your own, there is a HttpSessionStateWrapper in System.Web.Abstractions you could try.
