MiniMock

MiniMock offers a minimalistic approach to mocking in .NET with a focus on simplicity and ease of use.

    public interface IBookRepository
    {
        Task<Guid> AddBook(Book book, CancellationToken token);
        int BookCount { get; set; }
        Book this[Guid index] { get; set; }
        event EventHandler<Book> NewBookAdded;
    }

    [Fact]
    [Mock<IBookRepository>]
    public async Task BookCanBeCreated()
    {
        Action<Book> trigger = _ => { };

        var mockRepo = Mock.IBookRepository(config => config
            .AddBook(returns: Guid.NewGuid())
            .BookCount(value: 10)
            .Indexer(values: new Dictionary<Guid, Book>())
            .NewBookAdded(trigger: out trigger));
        
        var sut = new BookModel(mockRepo);
        var actual = await sut.AddBook(new Book());
        
        Assert.Equal("We now have 10 books", actual);
    }
