Difficulty thinking of properties for FsCheck
- by Benjol
I've managed to get xUnit working on my little sample assembly. Now I want to see if I can grok FsCheck too. My problem is that I'm stumped when it comes to defining test properties for my functions.
Maybe I've just not got a good sample set of functions, but what would be good test properties for these functions, for example?
//transforms [1;2;3;4] into [(1,2);(3,4)]
pairs : 'a list -> ('a * 'a) list //'
//splits list into list of lists when predicate returns
// true for adjacent elements
splitOn : ('a -> 'a -> bool) -> 'a list -> 'a list list
//returns true if snd is bigger
sndBigger : ('a * 'a) -> bool (requires comparison)
