Best practices to test Asp.net MVC applications

Whats the best practice to test an Asp.net MVC application?

From stackoverflow

• Choose your testing framework - I recommend xUnit.net.

  Decouple your classes using interfaces and use constructor injection in your controllers to satisfy dependencies. In your tests, pass mocks to your controllers using a mocking framework - I recommend MoQ.

  When running the web site rather than tests, either have default constructors on your controllers that call the other constructors and pass your real implementations of your interfaces; or use a Dependency Injection (DI) container to do it automatically - I recommend StructureMap.

  Hope that helps.
