I've notice a behaviour of quickcheck that is unexpected to me. With
this code:
import Test.QuickCheck
main = check myconfig
((\v - v == v) :: (Maybe Double,Maybe Double) - Bool)
myconfig = defaultConfig{configMaxTest=10,
configEvery = \n args - show n ++ :\n
your quick check property (in a different way of writing) is the following:
prop_1 :: Maybe Double - Bool
prop_1 v = v == v
but what you want is actually the following:
prop_2 :: Maybe Double - Maybe Double - Bool
prop_2 v1 v2 = v2 == v2
if I understood the problem correctly, using prop_2
There is a typo, in my previous post, It should have been: prop_2 v1 v2 = v1
== v2
not: prop_2 v1 v2 = v2 == v2
Moreover, I realised that the (nice) function verboseCheck doesn't exist in
QuickCheck 2. However you can always do the following in ghci, to see
whether my suggestion works or not:

I think you misunderstood me. The property was fabricated just for
