ASP.NET MVC Unit Testing RedirectResult

Question

I have a class that inherits from System.Web.Mvc.RedirectResult which overrides ExecuteResult. How do I unit test this?

Answer 1

Depends on what you override does.

In general, mock HttpContextBase, create the necessary RouteData and use those two elements to create a ControllerContext.

Instantiate your custom RedirectResult, call ExecuteResult passing in your previously created ControllerContext and then make assertions on the various bits and pieces that you mocked.

If you want a more comprehensive answer, I would need more details as to exactly what your override does.
