Using Moq to mock ASP.NET MVC HttpContextBase

Here’s my little example about how to use Moq to mock HttpContextBase and it’s members to make controller tests pass. You can use this code when you are not allowed to use open-source or use-on-your-own-risk pieces of software that provide you this kind on initialization using built-in features. Also it is good exercise that introduces you how to solve mocking problems.

Here’s the simple example to get started.

var controller = new MyController();

var server = new Mock<HttpServerUtilityBase>(MockBehavior.Loose);
var response = new Mock<HttpResponseBase>(MockBehavior

var request = new Mock<HttpRequestBase>(MockBehavior
request.Setup(r => r.UserHostAddress).Returns(

var session = new Mock<HttpSessionStateBase
session.Setup(s => s.SessionID).Returns(Guid.NewGuid().ToString());

var context = new Mock<HttpContextBase
context.SetupGet(c => c.Request).Returns(request.Object);
context.SetupGet(c => c.Response).Returns(response.Object);
context.SetupGet(c => c.Server).Returns(server.Object);
context.SetupGet(c => c.Session).Returns(session.Object);

controller.ControllerContext =
new ControllerContext
new RouteData(), controller);

Same way you can also mock other members of HttpContextBase.

    Nice and concise, but some explanation of your choices of strict mocks for some types and loose mocks for other types would be very helpful.

    Unfortunately, this does not work in core 1.1. Any ideas on how to do it?
