Question

In my Controller Action I set Cookie with Response.SetCookie(myCookie) method.
In my Unit Test method I would like to use Mock or better Stub to examine if all parameters have been set correctly. I am using MvcContrib TestHelper to setup HttpContext but I don’t know how to pass my fake Response object to it. I am using Moq and MvcContrib.

You need to mock HttpContext property on TestControllerBuilder yourself. HttContext is marked protected so your test class needs to inherit from TestControllerBuilder to be able to set it. I did it like this:

[TestClass]
public class SampleTest : TestControllerBuilder
{
    [TestMethod]
    public void TestLogOnActionSetsCookie()
    {
        var httpContextMock = new Mock<HttpContextBase>();
        var responseMock = new Mock<HttpResponseBase>();
        httpContextMock.Setup(c => c.Response)
            .Returns(responseMock.Object);

        responseMock
                .Setup(r => r.SetCookie(It.IsAny<HttpCookie>()))
                .Verifiable();

        var controller = new AccountController();

        base.HttpContext = httpContextMock.Object;
        base.InitializeController(controller);

        controller.LogOn();

        responseMock.Verify();
    }
}
