Implementing mocking objects with Moq when constructor has parameters

Question

I have read this answer by Ragzitsu for the same question. I am still confused how to implement things though. Can somebody give me an example of an implementation.

I have the following classes:

class Fizz : IFizz { }  class Buzz : IBuzz {  }  class Bar : IBar {  }  class Foo : IFoo {     public Foo(IBar bar, IFizz fizz, IBuzz buzz)     {         //initialize etc.     }      //public methods } 

What is the practical way to get around the constructor here? I want to do something like

var foo = new Mock<IFoo>(); 

In other words how would the code look after the advice

The best thing to do would be right click on your class and choose Extract interface.

You can create mock where constructor has param arguments, by referring MockBehavior, shown below

Mock<testClass>(MockBehavior.Strict, new object[] {"Hello"});
