This is just a quick announcement that the development version of
QuickCheck 2 is now available in a public darcs repository.
Some highlights:
- Shrinks failing test cases.
- Supports testing monadic code.
Wonderful. Many thanks for QC2! :-)
Thank Koen.
By the way, since Positive is a type synonym, the
StrictlyMonotonicFunction instance should perhaps be:
instance Arbitrary StrictlyMonotonicFunction where
arbitrary = StrictlyMonotonic `fmap` arbMonotonicFunction (\
(NonZero (NonNegative x)) -> x)
instead of:
instance Arbitrary StrictlyMonotonicFunction where
arbitrary = StrictlyMonotonic `fmap` arbMonotonicFunction (\
(Positive x) -> x)
Oops, thanks. How did I manage to push the change to Positive without
building? Now let's move any discussion about my silly mistakes off
this list.
