Unit Testing ASP.Net MVC Action result with call to Server.UrlDecode

We are trying to write Unit 开发者_如何学PythonTests in our ASP.Net MVC project.

Some of the methods in the controller contain a call to Server.UrlDecode

This fails with a null reference exception when called from a unit test.

Anybody have a solution for this?

Use the static HttpUtility class and its UrlDecode method.

HttpUtility.UrlDecode(mystring);
