Set property (type interface) without implementation

Question

I'm creating some UnitTests and want to mock a service which returns a Thing object with a FileInformation property that implements a IFileInformation interface.

How do I fill in / mock the Thing without writing a implementation for this interface?

public interface IFileInformation
{
   string Name { get; set; }
}
public class Thing
{
   public IFileInformation FileInformation { get; set; }
}

I'm using Moq lib for my UnitTests.

Ok, it was easier than I thought.

Using Moq to mock the interface.

Mock<IFileInformation> fileInformation = new Mock<IFileInformation>();
fileInformation.SetupGet(x => x.Name).Returns("whatever.txt");

Thing serviceResult = new Thing();
serviceResult.FileInformation = fileInformation.Object;
