MockOf: How neat is that?

Are you tired of using the object property in MOQ?

Are you tired of declaring a huge amount of local variables to declare complex hierarchies?

…

Have a look at the new Mock.Of<T> feature in MOQ! Let’s see an example.

    public interface ILibrary
    {
        string Name { get; }
        string Description { get; }
        IEnumerable<IBook> Books { get; }
        IEnumerable<ICategory> Categories { get; }
    }

    public interface IBook
    {
        string Name { get; }
        string ISBN { get; }
        string Description { get; }
        string Author { get; }
    }

    public interface ICategory
    {
        string Name { get; }
        IEnumerable<IBook> Books { get; }
    }

Use the new fluent api to configure your mock hierarchy…

            var library = Mock
                .Of<ILibrary>(l => l.Name == "TestLibrary"
                                   && l.Description == "Library used to demonstrate MOQ"
                                   && l.Books == new List<IBook>
                                                     {
                                                         Mock.Of<IBook>(b =>
                                                             b.Name == "The Wheel of Time Set I, Books 1-3"

                                                             && b.Author == "Robert Jordan"),
                                                       Mock.Of<IBook>(b =>
                                                             b.Name == "The Wheel of Time Set II, Books 4-6"

                                                       Mock.Of<IBook>(b =>
                                                             b.Name == "The Complete Robot"
                                                             && b.Description == "complete collection of Robot stories from Isaac Asimov."
                                                             && b.ISBN == "0586057242"
                                                             && b.Author == "Isaac Asimov")
                                                     }
                                   && l.Categories == new List<ICategory>
                                                          {
                                                              Mock.Of<ICategory>(c =>
                                                                  c.Name == "Fantasy"
                                                                  && c.Books == l.Books.Where(x => x.Author.Equals("Robert Jordan"))),
                                                              Mock.Of<ICategory>(c =>

                                                                  && c.Books == l.Books.Where(x => x.Author.Equals("Isaac Asimov")))
                                                          });

When printed to the console the hierarchy looks like:
