MVC Controller unit tests writing

I have a question related to unit tests. I have MVC controller in which i have different actions and i want to write unit tests on all actions.I have written unit tests on classes/functions using NUnit and VS Unit Test framework but Can you recommend any framework to write unit tests on controller actions?

Referencing Creating Unit Tests for ASP.NET MVC Applications (C#)

From what you have already stated you should be able to use the tools that you already have NUnit and VS Unit Test framework

For example

[Test]
public void TestDetailsViewData()
{
    var controller = new ProductController();
    var result = controller.Details(2) as ViewResult;
    var product = (Product) result.ViewData.Model;
    Assert.AreEqual("Laptop", product.Name);
}
