Thanks Ian. I think the matter of using HUnit or QuickCheck is not the most
relevant here. The real question his how to test a single function from GHC
sources (assuming that it is exported by module in which it is defined)? So
let's say there is a module in GHC I want to test:
module Foo where
foo x y = x + y
And I want to write tests for it in the testsuite:
module FooTests where
import Foo
main = ASSERT (foo 2 2 == 4)
ASSERT (foo 0 1 == 1)
and so on (Hunit would only be a convenient interface here). The question is
how can I import a GHC module from within the testsuite and call its functions
to test it they behave propertly? An attempt to simply import the module
results in compilation error:
Failed to load interface for ‛Foo’
It is a member of the hidden package ‛ghc-7.7.20130731’.
Use -v to see a list of the files searched for.
Is there a workaround for this?

It's better not to use HUnit/QuickCheck/SmallCheck, as then you can add
them to the testsuite and they can be run by everyone, without needing
the libraries to be installed.
Thanks
