FsCheck is a tool for testing .NET programs automatically. The programmer provides
a specification of the program, in the form of properties which functions, methods
or objects should satisfy, and FsCheck then tests that the properties hold in a
large number of randomly generated cases.
   
While writing the properties, you are actually writing a testable specification of your program.
   
Specifications are expressed in F#, C# or VB, using combinators defined
in the FsCheck library. FsCheck provides combinators to define properties,
observe the distribution of test data, and define test data generators.
When a property fails, FsCheck automatically displays a minimal counter example.

FsCheck.Xunit

FsCheck.Xunit integrates FsCheck with xUnit.NET by adding a PropertyAttribute that runs FsCheck tests, similar to xUnit.NET's FactAttribute. All the options normally available in vanilla FsCheck via configuration can be controlled via the PropertyAttribute.
FsCheck.NUnit

FsCheck.NUnit integrates FsCheck with NUnit by adding a PropertyAttribute that runs FsCheck tests, similar to NUnit TestAttribute. All the options normally available in vanilla FsCheck via configuration can be controlled via the PropertyAttribute.
Expecto.FsCheck The ID prefix of this package has been reserved for one of the owners of this package by NuGet.org.

Property testing for Expecto, powered by FsCheck
AutoFixture.Idioms.FsCheck The ID prefix of this package has been reserved for one of the owners of this package by NuGet.org.

Ubiquitous use of AutoFixture for unit testing has given rise to a number of idiomatic unit tests - unit tests that tend to follow common templates. The AutoFixture Idioms.FsCheck library encapsulates these idioms into reusable classes and methods.
MBrace.Tests

A collection of abstract NUnit-based test suites for evaluating MBrace runtime implementations.

AutoFixture/AutoFixture
AutoFixture is an open source library for .NET designed to minimize the 'Arrange' phase of your unit tests in order to maximize maintainability. Its primary goal is to allow developers to focus on what is being tested rather than how to setup the test scenario, by making it easier to create object graphs containing test data.

Improve reflection based generator for union cases - now also detect if a union case is recursive via any number of other types.
Improve shrinking - when many possible values are tried, the shrinking was not tail recursive which could lead to stack overflow in rare situations. (by Lukas Rieger)
Improvements to Experimental.StateMachine: some stats about generated operations are now printed and shrinking of operations can be customized (by Silvio Marcovic). Also the Setup shrinking phase now works correctly.
