[Haskell-beginners] HSpec output option

[Baa]

Hello, Dear List!

I have tests: I'm using HSpec (and QuickCheck too). And I have tests
like this:

  describe "Something" $ do
    it "something is correct" $ do
      ...blah-blah...
    it "any string is correct" $ property $
      \s -> all (=='*') (Something s) -- it's for example only!!!

so something like unit-test and property checks in one SomethingSpec.hs.

I'm running them with this Makefile:

  .PHONY: test fast-test

  fast-test:
  	stack exec runhaskell -- -isrc -itest test/Spec.hs

  test:
  	stack test

and in Spec.hs I have:

  {-# OPTIONS_GHC -F -pgmF hspec-discover #-}

That's all. So, when I find failed test, I get a trace like this:

  ...
  Failures:

    test/SomethingSpec.hs:172: 
     1) BlahBlah.superFunc any string is correct:
        result Gave up after 48 tests
  ...etc...

So, my question is: when QuichCheck runs my property test, it passes
argument to property's lambda. And on 48th test attempt with some
concreate argument value my check fails. How can I get detailed output
from such test environment, to see what concreate arguments lead to
failure? To see something (or similar/or more detailed even):

  Failed with arguments: s = ""

Is it possible (I run them with stack and with runhaskell too) ?
