Testing a class with HttpContext.Current.Session in ASP.NET MVC

Question

Hello. I'm adding some tests to a class that uses HttpContext.Current.Session internally and we are porting to ASP.NET MVC. My class looks like this:

class Foo
{
    public void foo()
    {
        HttpContext.Current.Session["foo"] = "foo";
    }
}

I thought to change it like this:

class Foo
{
    IHttpSessionState session;

    public Foo() : this(HttpContext.Current.Session) {}

    public Foo(IHttpSessionState session)
    {
        m_session = session;
    }

    public void foo()
    {
        m_session["foo"] = "foo";
    }
}

The problem is with the default constructor. I can't pass the old classes since they don't implement the new ASP.NET MVC interfaces.

Is there anyway to obtain the instances that implement IHttpSessionState in the default constructor?

Thanks

Try this, it used the IHttpSessionState wrapper that the MVC framework uses.

class Foo
{
    IHttpSessionState session;

    public Foo() : this(new HttpSessionStateWrapper(HttpContext.Current.Session)) {}

    public Foo(IHttpSessionState session)
    {
        m_session = session;
    }

    public void foo()
    {
        m_session["foo"] = "foo";
    }
}
