The most popular and friendly mocking library for .NET

  var mock = new Mock<ILoveThisLibrary>();

  // WOW! No record/replay weirdness?! :)
  mock.Setup(library => library.DownloadExists("2.0.0.0"))
      .Returns(true);

  // Use the Object property on the mock to get a reference to the object
  // implementing ILoveThisLibrary, and then exercise it by calling
  // methods on it
  ILoveThisLibrary lovable = mock.Object;
  bool download = lovable.DownloadExists("2.0.0.0");

  // Verify that the given method was indeed called with the expected value at most once
  mock.Verify(library => library.DownloadExists("2.0.0.0"), Times.AtMostOnce());

Moq also is the first and only library so far to provide Linq to Mocks, so that the same behavior above can be achieved much more succinctly:

  ILoveThisLibrary lovable = Mock.Of<ILoveThisLibrary>(l =>
    l.DownloadExists("2.0.0.0") == true);

  // Exercise the instance returned by Mock.Of by calling methods on it...
  bool download = lovable.DownloadExists("2.0.0.0");

  // Simply assert the returned state:
  Assert.True(download);
  
  // If you want to go beyond state testing and want to 
  // verify the mock interaction instead...
  Mock.Get(lovable).Verify(library => library.DownloadExists("2.0.0.0"));

You can think of Linq to Mocks as "from the universe of mocks, give me one whose behavior matches this expression".

AutoFixture.AutoMoq

This extension turns AutoFixture into an Auto-Mocking Container. The mock instances are created by Moq. To use it, add the AutoMoqCustomization to your Fixture instance. Read more at http://blog.ploeh.dk/2010/08/19/AutoFixtureAsAnAutomockingContainer.aspx

Moq.AutoMock

An auto-mocking container that generates mocks using Moq

MockQueryable.Moq

Extension for mocking Entity Framework Core operations such ToListAsync, FirstOrDefaultAsync etc. When writing tests for your application it is often desirable to avoid hitting the database. The extension allows you to achieve this by creating a context – with behavior defined by your tests – that makes use of in-memory data.

Autofac.Extras.Moq

Autofac extension for automocking and creation of mock objects in Moq.

Moq.EntityFrameworkCore

Library that provides methods that will help you with mocking Entity Framework Core.
