How to use cookies in xUnit?

Question

ASP.NET

I wrote an Action of some controller, as well as a test for it. The problem is that the Action uses the value from the cookie, and the test, when trying to execute this Action, throws an error System.NullReferenceException : Object reference not set to an instance of an object. on the line with cookies. How can I write a test for my Action without changing it, and does this mean that I'm doing something wrong and my application architecture is bad?
