FsCheck 2.0.5

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

Make Gen operators <*> and <!> actual operators on the Gen type, instead of functions to avoid name clashes. (by Paul Young)
Add FsCheck.Experimental.StateMachine for more advanced state machine-based checking, i.e. for mutable systems.
Fix GenBuilder.delay so that generators inside gen computation expression are not needlessly re-created.
Add Fun active pattern to make using shrinkable and printable functions easier.
