The simplest mocking library for .NET 3.5/4.0 and Silverlight with deep C# 3.0 integration.

NUnit features a fluent assert syntax, parameterized, generic and theory tests and is user-extensible. A number of runners, both from the NUnit project and by third parties, are able to execute NUnit tests. Version 2.6 is the seventh major release of this well-known and well-tested programming tool. This package includes only the framework assemb... More information

A very extensive set of extension methods that allow you to more naturally specify the expected outcome of a TDD or BDD-style unit test. Runs on .NET 3.5, 4.0 and 4.5 (Desktop and Windows Store), Silverlight 4 and 5 and Windows Phone 7.5. Supports the unit test frameworks NUnit, XUnit, MBUnit, Gallio and MSpec.

Rhino Mocks is using Castle Dynamic Proxy (http://www.castleproject.org/dynamicproxy/index.html) to handle proxying the types it needs to mock. The Dynamic Proxy project has been invaluable resource and made creating Rhino Mocks possible.

NSubstitute is a friendly substitute for .NET mocking frameworks. It has a simple, succinct syntax to help developers write clearer tests. NSubstitute is designed for Arrange-Act-Assert (AAA) testing and with Test Driven Development (TDD) in mind.

Machine.Specifications is a Context/Specification framework geared towards removing language noise and simplifying tests.

Through a fluent, extensible interface, NBuilder allows you to rapidly create test data, automatically assigning values to properties and public fields that are one of the built in .NET data types (e.g. ints and strings). NBuilder allows you to override for properties you are interested in using lambda expressions.

It's faking amazing! The easy mocking framework for .NET that works great in C# and VB.NET alike. No need to know the difference between a stub, a mock or a spy, everything's a fake! The easy to use, refactoring friendly API makes faking a breeze.

NSpec is a BDD (Behavior Driven Development) framework for .NET of the xSpec (Context/Specification) flavor. NSpec is intended to drive development by specifying behavior within a declared context. NSpec is heavily inspired by RSpec and build upon the NUnit assertion library.

Machine.Fakes attempts to simplify the usage of such frameworks on top of Machine.Specifications by helping to reduce a lot of the typical fake framwork related clutter code in specifications. If you choose so, Machine.Fakes even helps you to stay mostly independent of a concrete fake framework by providing a little wrapper API and a provider model... More information

An open source code coverage tool (branch and sequence point) for all .NET Frameworks 2 and above (including Silverlight). Also capable of handling 32 and 64 bit processes. Use ReportGenerator 1.7 for best viewing results (also available via Nuget).

Utility classes to make it easier to test first. Currently contains: - RandomDataHelper - Rob Connery's TestBase

Contributed features and third-party integration for Moq.

NUnit.Mocks was originally developed for internal use in NUnit's own tests, although we no longer use it for that purpose. In addition, it has been useful as a teaching tool, allowing users to gain familiarity with mocking techniques before moving on to more serious frameworks. For production use, we recommend you install a full-featured mock obj... More information
