    Hi,

    Some 5+ years ago, Jonas Högström helped us create an ASP.NET WebForms application, that was later converted to a hybrid WebForms/MVC application. During this process one of us (probably me) created a MasterController class, based, I think, on template code from CapableObjects.

    This MasterController has evolved, since then, but I think this code is from the template:

    protected OurEcoSpace EcoSpace
    {
        get
        {
            EnsureEcoSpace();
            return ecoSpace;
        }
    }
    
    private void EnsureEcoSpace()
    {
        if (ecoSpace == null)
        {
            if (ecoSpaceStrategyHandler == null)
                ecoSpaceStrategyHandler = new EcoSpaceStrategyHandler(
                    SessionStateMode,
                    typeof(OurEcoSpace),
                    SessionStateKey,
                    UsePool
                );
            ecoSpace = (OurEcoSpace)ecoSpaceStrategyHandler.GetEcoSpace();
            RegisterServices(ecoSpace);
        }
    }

    Now, I’m trying to unit test a controller, that references the property EcoSpace, but it throws an exception at the call of ecoSpaceStrategyHandler.GetEcoSpace(), saying there’s no session, and to use GetSessionFreeEcoSpace() instead.

    I use NSubstitute to mock a session:

    var context = Substitute.For<ControllerContext>();
    var session = Substitute.For<HttpSessionStateBase>();
    context.HttpContext.Session.Returns(session);
    MyController c = new MyController() { ControllerContext = context };

    But this doesn’t help. I even tried creating a “real” session state class with a simple Dictionary instead of the mock of HttpSessionStateBase, but that doesn’t help either.

    So, what do I need to do, to get EcoSpaceStrategyHandler to “find” a session state object?

    When you create EcoSpaceStrategyHandler you need to say SessionStateMode.Never
    Did you do that?
    What it controls is when to destroy the ES

    Yes, this is the code:

    private void EnsureEcoSpace()
    {
        if (ecoSpace == null)
        {
            if (ecoSpaceStrategyHandler == null)
                ecoSpaceStrategyHandler = new EcoSpaceStrategyHandler(EcoSpaceStrategyHandler.SessionStateMode.Never, typeof(DiamondsEcoSpace), null, false);
            ecoSpace = (DiamondsEcoSpace)ecoSpaceStrategyHandler.GetEcoSpace();
        }
    }

    To work around the problem I added a constructor to the controller class that takes an explicit EcoSpace as a parameter, and in that case never instantiates its own, nor an EcoSpaceStrategyHandler. Works.
