A 'Testable may be a function of any number of parameters that returns bool or unit
Your members are not functions. Try static member ``should be true``() = true
from fscheck.
Thanks @kurtschelfthout! That input solves my issue. I did some more digging though and found a few confusing things that I want to report for anyone else having similar problems. All the confusion relates to "functions" returning unit behaving different than functions returning bool:
open FsCheck
type Tests =
static member ``case 0`` : Unit -> Unit = fun () -> () // :-)
static member ``case 1`` = fun () -> () // :-)
static member ``case 2`` () = () // :-(
static member ``case 3`` (x:int) : Unit = () // :-(
static member ``case 4`` : int -> Unit = fun x -> () // :-)
static member ``case 5`` = fun x -> () // :-)
static member ``case 6`` (x:int) = x = x // :-)
static member ``case 7`` (x:int) : bool = x = x // :-)
static member ``case 8`` x = x = x / 1 // :-)
static member ``case 9`` : int -> bool = fun x -> x = x // :-)
Check.QuickAll<Tests> ()
Check.Quick ("case 2", Tests.``case 2``)
Check.Quick ("case 3", Tests.``case 3``)
The output is:
--- Checking Tests ---
Tests.get_case 0-Ok, passed 100 tests.
Tests.get_case 1-Ok, passed 100 tests.
Tests.get_case 4-Ok, passed 100 tests.
Tests.get_case 5-Ok, passed 100 tests.
Tests.case 6-Ok, passed 100 tests.
Tests.case 7-Ok, passed 100 tests.
Tests.case 8-Ok, passed 100 tests.
Tests.get_case 9-Ok, passed 100 tests.
case 2-Ok, passed 100 tests.
case 3-Ok, passed 100 tests.
I also see that the output sometimes prepends get_ to the name of the test...
This leaves me in a situation where I just have to adapt the format of the test members, depending if they return bool or unit, which is fine, but potentially confusing when in the future someone tries to conform to a single format.
