Why is my ASP.NET Web API ActionFilterAttribute OnActionExecuting not firing?

Question

I\'m trying to implement what\'s seen here: http://www.piotrwalat.net/nhibernate-session-management-in-asp-net-web-api/ but I\'m having an issue with my NhSessionManag

For anyone else who comes across this, ActionFilterAttribute will not fire when calling YourController.YourAction from your UnitTest.

[TestMethod]
public void RevokeSiteAdmin_SessionOver()
{
    FakeDbContext db = new FakeDbContext();

    YourController controller = new YourController(db);
    var result = controller.YourAction();

    //Some Assertions
}

In the TestMethod above, any ActionFilterAttributes on YourController.YourAction will not be called. However; if you call YourController.YourAction from a browser, your ActionFilterAttribute will be called.

This is true for at least WebApi, but I don't know if it applies to MVC.
