How do I make a unit test to test a method that checks request headers?

Question

I am very, very new to unit testing and am trying to write a test for a pretty simple method:

public class myClass : RequireHttpsAttribute
{
    public override

I encountered an issue with the accepted solution using ASP.NET MVC 4. To resolve it I mocked the http context Items attribute otherwise the sut.OnAuthorization was causing an object is undefined exception:

MockHttpContext.Setup(x => x.Items)
    .Returns(new System.Collections.Generic.Dictionary());
