FsCheck 2.1.0

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.

There is a newer version of this package available.

Release Notes

Switch to xunit 2.1. Note: Needs -noshadow argument on Mono due to Mono bug. A fix for Mono
is submitted and is expected in Mono 4.3. (heroic achievement by Jon Hamm - thanks to all who tested early versions and found bugs.)
xunit versions < 2.1 are no longer supported. The latest FsCheck version that supports xunit 1.9.2 is currently FsCheck.Xunit 2.0.7.
Made Arbitrary overrides (e.g. using Arb.register, passing arbitrary to Config, or setting them
in PropertyAttribute) thread-local. This is mainly to support xunit2: it runs tests in the same class
in parallel by default. Not making the overrides thread local causes overrides from one test to mistakenly apply
to others.
FsCheck.Runner.init is Obsolete, it should not longer be necessary to call it explicitly. (though
I am cautious here - please report any issues.)
Fix for AppVeryor NuGet feed dependency problem.
