moq webapi identity problem

My attributes fire when debugging locally using the Composer tab in Fiddler, but when I attempt to write a unit test it does not fire the [Authorize] attribute on my method.
This code does not run my Authorize attribute on my request.
[TestMethod] public void TestGet() { var controller = new UtilityRateController(/* need a repository here */); // act var result = controller.Get("92128"); }
