ASP.NET MVC unit test controller with HttpContext

Question

I am trying to write a unit test for my one controller to verify if a view was returned properly, but this controller has a basecontroller that accesses the HttpContext.Curr

Answer 1

Unless you use Typemock or Moles, you can't.

In ASP.NET MVC you are not supposed to be using HttpContext.Current. Change your base class to use ControllerBase.ControllerContext - it has a HttpContext property that exposes the testable HttpContextBase class.

Here's an example of how you can use Moq to set up a Mock HttpContextBase:

var httpCtxStub = new Mock();

var controllerCtx = new ControllerContext();
controllerCtx.HttpContext = httpCtxStub.Object;

sut.ControllerContext = controllerCtx;

// Exercise and verify the sut

where sut represents the System Under Test (SUT), i.e. the Controller you wish to test.
