FsCheck 2.7.1

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.

Release Notes

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.
