[back to package description]tasty-leancheck: LeanCheck support for Tasty
LeanCheck support for the Tasty test framework. Tasty and healthy tests.
Installing
$ cabal install tasty-leancheck
Example
(This example is intentionally similar to Tasty's official example.)
Here's how your test.hs might look like:
import Test.Tasty
import Test.Tasty.LeanCheck as LC
import Data.List
main :: IO ()
main = defaultMain tests
tests :: TestTree
tests = testGroup "Test properties checked by LeanCheck"
[ LC.testProperty "sort == sort . reverse" $
\list -> sort (list :: [Int]) == sort (reverse list)
, LC.testProperty "Fermat's little theorem" $
\x -> ((x :: Integer)^7 - x) `mod` 7 == 0
-- the following property do not hold
, LC.testProperty "Fermat's last theorem" $
\x y z n ->
(n :: Integer) >= 3 LC.==> x^n + y^n /= (z^n :: Integer)
]
And here is the output for the above program:
$ ./test
Test properties checked by LeanCheck
sort == sort . reverse: OK
+++ OK, passed 200 tests.
Fermat's little theorem: OK
+++ OK, passed 200 tests.
Fermat's last theorem: FAIL
*** Failed! Falsifiable (after 71 tests):
0 0 0 3
1 out of 3 tests failed (0.00s)
Options
The tasty-leancheck provider has only one option, --leancheck-tests:
$ ./test --leancheck-tests 10
Test properties checked by LeanCheck
sort == sort . reverse: OK
+++ OK, passed 10 tests.
Fermat's little theorem: OK
+++ OK, passed 10 tests.
Fermat's last theorem: OK
+++ OK, passed 10 tests.
